THERE is one peculiarity ia the follow- ing account of Reptiles and Serpents, which it may be useful to mention to the young reader. The Frog is the only animal in the collection which is found in Ireland. Amongst tha re- mainder, the Viper and the Toad, together with one or two kinds of harmless Ser- pents and the Nimble Lizard, are natives of England, but the whole number, whe- ther harmless or hurtful, with the excep- tion already mentioned, are unable to bear our climate. Every one has, doubtless, heard, that vonernous animals do not exist amongst us ; but whatever may be the 2091183 Vi PREFACE. cause, (and it proceeds, most probably, from the coldness of our atmosphere,) we should not forget to thank Him, whose gift it is, that we can walk through our fields, without fearing in- jury from those deadly animals, which are found in the hotter parts of the earth. In the Appendix will be found a brief account of Worms, Corals, and Sponges, the next classes which occur as we descend, in the history of Animals. Their structure becomes gradually more simple, and their powers fewer ; but it is well deserving of observation, how ad- mirably fitted to the station allotted to it each is by Almighty Wisdom.

J. HE common Tortoise rarely exceeds eight inches in length, and seldom weighs more than three pounds. Its shell is composed, (as in all the varieties of this aniiiial) of thirteen middle pieces, and About twenty- five marginal ones. The legs are short, and the feet covered with strong scales, and armed with four strong claws. The tail is ratflf.r shorter than the. legs and covered with small scales.- which erid ^tth a hard pointed tip. Thus we see the Tortoise ha* an advantage, which most otber animals have not. From the moment !' its breaking the B 10 shell, it has a soKd and durable house, strong enough to resist its enemies, and yet not fixed 10 one spot. It carries every where the dwell- ing which nature has furnished for its defence, and under it, can dwell in perfect security. This species reside* princi pally in burrows that it forms in the ground. In these, it sleeps away the greatest part f its time, appearing abroad only for a lew hours in the middle of each day. It feeds on various kinds of herbs, fruit, worms, snails, and insects. Its manners are exceedingly gentle and peaceable; hence it is easily domesticated, and is an agreeable ob- ject in gardens, where it destroys noxious slugs and insects. In defecl of its usual food, it may be supplied with, and will live sufficiently well on, bran or meal. In the autumn, i( retires to some hiding place 1 under the surface of the earth, where it remains in a state of torpor for four or five months, not again making its appearance abroad, until re- called into life by the warmttrof the sun in spring. About the beginning of June, the female, when in her native state, scratches a hole in some warm situation* where she deposits four er live eggs. These are hatched in September ; and the young ones, \vhen they first come into the world, are not bigger than a walnut. This small specief;, which is sometimes met in a domesticated state, often arrives at a great age, even beyond the period of a century. One 11 of these thai was brought into the arohbishop"s palace at Lambeth, about the year 1633, was still living, in the year 1753, and then was thought to have died from neglect, rather than from old ago. In the year 1765. a tortoise was living in the garden of Samuel Simmons, Esq. at Landwich, in Kent, which was known to have been there eighty-six years ; but how Jong be- fore that period, no one could say with authority. It was on the premises before Mr. Simmons took them, and was supposed to have been brought there from the West Indies, by the former pos- sessor. This creature received a considerable injury about thirty years before it died, from the wheel of a loaded waggon, which went over it and cracked its shell. It was always extremely alarmed when sur- prised by a sudden shower of rain, during its peregrinations for food, shuffling away on the first sprinklings, and always, if possible, cun- ning its head up into a corner. It thus became an excellent barometer; for if h walked elate, and, as it were, on tiptoe, feeding with great earnestness, in a morning, there was almost invariably, rain before night. Mr. White, of Selbourne, attended accurately to the manners of one that was in the possession of a ladv of his acquaintance (who resided in Sussex.) upwards of thirty years. It regularly retire"d underground, about the middle of No- vember, from whence it did not come forth until 12 about the middle of April. Its appetite was always most voracious in the height of summer, eating very little either in the spring or autumn. Milky plants, such as lettuces, dandelions, and sowthistles, were its principal food. Mr. White was much pleased with the saga- city of the above-mentioned animal, in distin- guishing those persons from whom it was accus- tomed to receive attention. Whenever the good old lady came in sight, who had waited on it for more than thirty years, it always hobbled, with all the alacrity it could use, towards its benefactress, whilst to strangers it was altogether inattentive. Thus, not only " the ox knoweth his owner and the ass his master's crib," but the most torpid of creatures distinguished the hand that fed it, and exhibited marks of gratitude not always to be found in superior orders of animal being. It never stirred out after dark, and very frequently appeared abroad for a few hours only in the middle of the day, in wet days it never came at all from its retreat. Although this Tortoise loved warm weather, yet he care- fully avoided the hot. sun, since his thick shell, when once heated, must have become extremely painful, and probably dangerous to him. He therefore spent the more sultry hours under the shade of a large cabbage leaf, or amidst the waving stems of an asparagus bed. But, as he endeavoured to avoid the heat in the summer, he impwved the faint autumnal beams by get- 13 ting within the reflection of a fruit-tree wall ; and taught by that wonderful instinct with which kind Providence endues all animals,ihe frequently inclined his shell, by tilting it against the wall, to collect and admit every feeble ray. This animal was at last given to Mr. White, and in the month of March, 1780, he dug it out of its winter residence in order to convey it to his own house in Hampshire. The spring was a backward one ; but the animal was become sufficiently recovered from its torpidity to ex- press its resentment for the disturbance, by hiss- ing. It was packed in a box, and carried eighty miles in post-chaises. The rattle and hurry of the journey so roused it, that, when it was turned out on a border in Mr. White's gar- den, it walked twice down to the bottom. In the evening, however, the weather being cold, it buried itself in the loose mould, and remained concealed for above a month. Towards the time of its coming forth, it opened a breathing place in the ground near its head, requiring, no doubt, a free respiration as it became more lively. On the twenty-first of April, it heaved up the mould and put out its head ; and on the following morning, issued forth from its retreat, and walked about until four o'clock in the after- noon. The Great Mediterranean Turtle is the largest of the turtle kind with which we are ac- quainted. It is found from five to eight feet B 2 14 long, and from six to nine hundred pounds weight. But, unluckily, its utility bears no proportion to its size ; as it LS> untit foY food, and sometimes poisons those who eat it. The shell also, which is a tough strong; integument, re- sembling a hide, is unfit tor all ^rviceable pur- poses. One of these animal* was taken in the year 1729, at the mouth of the Loire, a river of France, in nets that were not designed for so large a capture. This Turtle, which was of enormoas strength, by its own struggles involved itself in the nets in such a manner as to be in- capable of doing mischief: yet, even thus shackled, it appeared terrible to the fishermen, who were at first for flying; hot finding it im- potent, they gathered courage to drag it on shore, where it made a most horrible bellowing; and was to be heard at half a mile's distance. They were still further intimidated by its nause- ous and pestilential breath, which so powerfully affected them, that they were near fainting. This animal wanted but four inches of being eight feet long, and was above two feet broad 9 its shell more resembled leather than the shell of a tortoise ; and, unlike all'other animals of this .kind, it was furnished with teeth in etehjaw, one rank behind another, like those of a\feark : its feet also, different from the rest of this k>nd, wanted claws ; and the tail was quite disengaged from the shell, and fifteen inches long, more re- sembling that of a quadruped than a Tortoise. 15 This animal was then unknown upon the ceasts of France ; and was supposed to hare been brought into the European seas, in som In- dia ship that was wrecked upon her return. Since that, however, two or three of these ani- jnal.s have been taken upon the coasts ; two in particular on those of Cornwall, in the year 1 756, the largest of which weighed eight hun- dred pounds ; and one upon the Isle of Rhea, but two years before, that weighed between seven and eight hundred. One, most probably of this kind also, was caught near Scarborough, in England, and a good deal of company was invited to feast upon it , a gentleman, who was .one of the guests, told the company that it was a Mediterranean Turtle, and not wholesome ; but a person who was willing to satisfy his ap- petite at the risk of his life, eat of it; he was seized with a violent vomiting and purging ; but his constitution overpowered the malignity of the poison. Theso^ however, are a formidable and useless kind, if compared to theTunle caught in the South Seas and the Indian Ocean. These are of different kinds ; not only unlike each other in form, but furnishing man with very different advantages. They are usually distinguished by sailors into four kinds; the Trunk Turtle, the Loggerhead, the Hawkshil], and the Green Turtle. The Trunk Turtle is commonly larger than a 16 the rest, and its back higher and rounder. The flesh of this is rank, and not very wholesome. The Loggerhead is so called from the large- ness of its head, which is much bigger in pro- portion than that of the other kinds." The flesh of this also is very rank, and not eaten but int case of necessity. The Hawksbill Turtle is the leaet of the four, and has a long and small mouth, somewhat re- sembling the bill of an hawk. The flesh of this is also very indifferent eating ; but the shell serves for the most valuable purposes. This is the animal that supplies the Tortoise-shell, of which such a variety of beautiful trinkets are made. The substance of which the shells of other Turtles are composed, is thin and porous ; but that of the Hawksbill is firm, and, when polished, ia beautifully marbled. They generally carry about three pounds ; but the largest of all six pounds. The shell consists, as in all the kinds, of thirteen leave?, or plates, of which eight are flat, and five hoHow. They arc raised and taken off by means of fire, which is made under the shell, after the flesh is taken out. As soon as the heat affects the leaves, they start from the ribs, and are easily raised with the point .of a knife. By being scraped and polished on both sides, they become beauti- fully transparent; or are easily cast into what- tyer form the workmen thinks proper, by mak- ing them soft and pliant in warm water, and then 17 screwing them in a mould, like a medal : how- ever, the shell is most beautiful before it under- goes this last operation. The green Turtle; which has so long, been es- teemed as an article of luxury by the rich, is so nam- ed, from the green colour of its fat. It abounds in the West Indies to such a degree, that Catesby says,40 sloops are employed by the inhabitants of Port Royal in Jamaica, for the sole purpose of catch- ing them ; and that the markets are there sup- plied with turtles, as ours are with butcher's meat. It is found also, in great quantities, on the coasts of all the other islands and continents in the middle parts of the earth. These places produce vast quantities of sea plants, which though covered by the water, are near enough to the surface to be readily seen by the naked eye, in calm weather ; amidst these sub-marine pastures, great numbers of green turtle are of- ten seen, feeding quietly on the plants which are produced there. The length of the green Turtle is sometimes upwards of six feet, arid the weight five or six hundred pounds. Dampier mentions an im- mensely large one that was caught at Port-Royal, in the Bay of Campeachy. It was nearly six feet in width, and four feet in thickness. A son of Captain Roch. a boy about ten years old, went in the shell, as in a boat, from the shore to his father's ship, lying about a quar- ter of a mile distant. B3 18 After having satisfied ifs appetite upon the grass, sea weed, and other plants which grow at the bo'.tom, the turtle often times retires to the fresh water, at th mouth of the great riv- ers, where it floats on the surface, holding its head above, for the purpose of brealhiug the fresh air. But as it is surrounded with many dangers, both from its enemies of the deep and from mankind, it is obliged to use great precau- tion in thus indulging itself with cool air, and with the refreshing streams of river water. The instant it perceives even the shadow of an ob- ject, from which it suspects danger, it dives to the bottom for security. The account which Cafesby has given respect- ing the manner in which the inhabitants of the Bahama islands, in the West Indies, catch their turtles, is very satisfactory. 4 * These people," he says, " go out in the month of April, in little boats, to Cuba, and other neigh- bouring islands, where in the evening, especially in moonlight nights, they watch the going and returning of the turtle to and from their nests, at which time, they turn them on their bac&s, when they leave them and pass on, turning all they find ; some are so large that it requires three men to turn one of them, and these must often employ even handspikes, for that purpose. Once they are laid on their bae.k, the upper shell is so flat, that they are quite helpless, and can never more recover tjieir feet.'' 19 But many turtles are lakftn not on land but in the sea, and at a considerable distance from the shore. Those are struck with a kind of spear, whose shaft i about lour yards in length. For this work, two men usually get into a simill and light boat, or canoe, one to paddle if gently along, and steer, and the other to stand at the head with his weapon. Sometimes the Tur- tles are discovered swimming with their head and back out of water ; but they are most com- monly seen lying at the bottom, where the wa- ter is a fathom or more in depth. If the ani- mal perceives that he is discovered, he im- mediately attempts to escape. The men pursue and endeavour to keep him in sight, and gene- rally so far tire him, that, in the course of half ao hour, he sinks to the bottom, which affords them an opportunity to strike him with the spear through -the shelJ. The head of the spear, which now slips off and is loft in his body, is fastened with a string to the pole ; and by means of this apparatus, they are enabled 10 pursue him, if he should not be sufficiently spent without : if however, that is the case, be tamely submits to be taken into the boat, or hauled ashore. In some parts of the South Seas, a peculiarly dexterous method is adopted of catching Turtlei. A bold diver throws himself into the water, at some distance from the place where the Turtles are observed floating asleep on the surface. He dives under the animals, and rising gently be- 20 Kind one of them, seicet the upper shell just be- hinjj lift ta8, aid pressing down the hinder part in the water, obliges the fore-part of the animal BOW awakened, te keep upright, and thus pre- vents it from diving, until his companions come with a boat, and take him and his prey on board. Green Turtles are sometimes caught on the European shores, driven thither by stress of weather. In the year 1752, one, six feet long and four broad, weighing betwixt eight and nine hundred pounds, was caught in the harbour of Dieppe, after a storm. In 1754, a still larger one, upwards of eight feet long, was caught Bear Antioche, and was carried to the abbey of Long-veau, near Vannes, in Brittany; and a fw years ago a small one was caught amongst the submarine rocks nrar Christchurch, Hants. The introduction of the Turtle, as an article of luxury, into England, appears to have taken f\3w. within the last seventy years. We im- part them principally, if not entirely, from the We* India islands. 21 THE COMMON FROG. IT is not necessary to enter into a minute description of an animal so well known as the Frog. Its whole appearance is lively, and its form by no means inelegant. The limbs are well calculated for aiding the peculiar motions of the animal, and its webbed hind feet for assisting its progress in the water, to which it occasionally retires during the heats of summer, and again in the frosts of winter. During the latter period, and till the return of warm wea- ther, it lies in a ttate of torpor, either deeply plunged in the soft mud at the bottom ot stag- nant waters, or in the hollows beneath iheir banks. Immediately on coming forth in the spring, they change their skin, and this opera- tion they repeat, generally about every eight or ten days, through the whole summer. The old skin, after it is entirely separated from the body, resembles rather a kind of thin mucus, than a membrane. The spawn of this Frog,which is generally cast in the month of March, consists of a clustered mass of jelly-like transparent, and round eggs, from six hundred to a thousand in number, in the middle of each of which, is contained the embryo or tadpole, in the form of a black speck. This at first sinks to the bottom of the water ; but when tht eggs begin to enlarge, in oonse* 22 *juence of becoming proportionally lighter, it rises to thefsurlace. About the thirty-ninth day, the little annuals begin to have motion. They are then so perfectly unlike the Frog in its complete state, that no person could suppose any relation- ship existed between them. The Tadpole ap- pears to consist merely of head and tail, the former large, black aad roundish, the latter slender and bordered with a broad transparent tinny margin. At first it quits the matter in \vhich it was enclosed only occasionally, as if to try its strength, and soon afterwards returns, apparently for the double purpose of retreat and nourishment, When the animal is about six weeks old, the hind. legs appear, and in about a fortnighf, these are succeeded by the fore-legs. The animal now bears a kind of ambiguous appearance, partaking of the forai of a Frog and a Lizard. The tail, at this period, begins to decrease, at first very gradually ^ and at length o rapidly, as to disappear in the space of a day or two afterwards ; the form is then completed, and the animal for the first time, ventures upon land. With this wonderful change of body, the animals also change their food, and instead of their former vegetable diet, live upon the smaller species of snails, worms, and insects; the struc- ture of their tongue is admirably adapted for seizing and securing this prey, the root is 23 attached to the fore-part of the mouth, so that when unemployed, it lies with the tip towards the throat. The animal by this singular contri- vance, is enabled to bend it to a considerable distance out of its mouth. When it is about to seize oil any object, it darts it out with great agility, and the prey is secured 0n its broad and jagged gluey extremity. This it swallows with so instantaneous a motion, that the eye can scarcely follow it. Nothing, however, can ap- pear more awkward than a Frog engaged with a large worm or small snake ; lor nature seems to have put a restraint upon the voracity of these animals, by forming them very inaptly for seizing and holding their larger prey. Dr. Townson had a large Frog, that one day swal- lowed in his presence a blind-worm, near a span long, which in its struggles frequently got half its body out again ; and when completely swallowed, its contortions were very visible in the flaccid sides of its victor. About the end of July, when the young Frogs have entirely laid aside their tadpole shape, they quit the water, and soon afterwards emi- grate into the woods and meadows. The com* mencement of their journey is always in the evening. They travel all night, and conceal themselves during the day, under stones, -or in other recesses ; and resume their journey only when the night begins. In the day time, how- 24 ever, whenever it happens to rain, they always come out of their retreats, as if to refresh them- selves in the falling moisture. Mr. Ray informs us, that as he was riding one afternoon in Berkshire, he was much surprised at seeing an immense multitude of Frogs crossing the road. On further examination, he found two or three acres of ground nearly covered with them ; they were all proceeding in the same direction, to- wards some woods and ditches that were before them. He traced them back to the side of a very large pond, which in the spawning-time, he was informed, always so much abounded with Frogs, that their croaking was frequently heard at a great distance. However singular it may appear, the fact is well ascertained, that Frogs will sometimes fasten upon the backs of fish, so as not to be easily disengaged. Mr. Pennant mentions that in a pond in Dorsetshire, great numbers of Carp were found, each having one of those animals clinging to it ; the hind legs were upon the back, and the fore legs attached to the cor- ner of each eye ; the Carp also was much was- ted away, being teased by its little persecutor. Frogs are numerous throughout Europe, and in the parts of America, about Hudson's Bay, as far north as latitude 61 deg. They frequent there the margins of lakes, ponds, rivers, and swamps; and, as the winter ap- proaches, thy burrow under the moss, at a 25 considerable distance from the water, where they remain in a frozen state till spring. Mr. Hearne says, he has frequently seen them dug up with the moss, frozen as hard as ice. la thig state, their legs are as easily brokenfoff as the stem of a tobacco-pipe, without giving them the least sensation : but, by wrapping them up in warm skins, and exposing them to a slow fire, they soon come to life, and the mutilated animals gain their usual activity. If, however, they are permitted to freeze again, they are past all recovery. The croaking of Frogs is well known io all persons in the country, who live in the neigh- bourhood of marshy lands. In the fens of Lin- colnshire, in England, these animals have, in consequence of this noise, received, among the common people, the appellation of Dutch Nightingales. For a whole month, in the heat of summer, they, however, become entirely silent ; and this period is called by the country people of many parts of England, the Paddock Moon. There is another kind of Frog considerably larger than the one we have been describing, which is made use of as an article of food on the Continent, and is acknowledged by all who can overcome their prejudices, to be both nutritive and delicate. Its colour is an olive green, distinctly marked with black patches on the back, and on its limbs with cros bare of the same. From the tip of the nose, three distinct 26 stripes of pale yellow extend to the extremity of the body, the middle one slightly depressed", and the side ones considerably elevated. The under parts are of a pale whitish colour, tinged with green, and marked with irregular brown spots. Tiiese creatures are brought from the country thirty or forty thousand at a time, to Vienna, and other great towns on the continent, and sold to the great dealers, who have conservato- ries for them, which are large holes, four or five feet deep, dug in the ground, the mouth ' covered with a board, and in severe weather with straw. In these conservatories, eyen dur- ing a hard frost, the Frogs never become quite torpid. When taken out atul placed on their backs, they are always sensible of the change, and have strength enough to turn themselves. They instinctively get together in heaps, one upon another, and thereby remain fresh and moist; for no water is ever put to them. lu Vienna, in the year 179.3, there were only three great dealers ; by whom most of those persons were supplied who brought them to the market ready for the cook. The Edible Frogs are caught in various ways : sometimes in the night, by means af nets, collecting together round the light of tor- ches carried out for the purpose ; or sometimes by hooks, baited with worms, insects, fle.sh, or even a bit of red cloth. Being exceedingly 27 voracious, they seize greedily, every thing that moves, and, when onee they have fixed, they keep thir hold with great obstinacy. In Swit- zerland, they are caught by means of large rakes, with long 1 , close-set teeth, which are thrown into the water, and drawn suddenly out again. The Frogs already described, however, can- not be compared in size with the Bull Frog, which frequently measures a foot and a halt, or upwards, from the nose to the hind feet. In Virginia, in North America, they are in such abundance, that there is scarcely any where a spring that hag not a pair of them. When sud- denly surprised, by a long leap or two, they ,nter the hole, at the bottom of which they lie perfectly secure. Their croaking somewhat resembles the hoarse lowing of a bull; and, in a calm night, when many of them are making a noise together, they may be heard to the distance of a mile mid a haif. The night is the time when they croak, and they are said to do it at intervals. In this act, .they are either hidden among the grass or rushes, or they are in the water, with their heads above the surface. Kalm informs us, that as he was one day riding out, he heard one of them roaring .before him, and supposed it to be a bull hidden in the bushes at a ^itlle distance. The voice was indeed more hoarse than that of a bull, yet, it was much too loud for him to conceive that it could be emitted by so small an animal as a Frog, and he was in considerable alarm for his safety. He was undeceived a few hours after- wards, by a party of Swedes, to whom he had communicated his fears. When alarmed, they leap to a most sur- prising distance at each exertion. A full-grown Bull Frog will sometimes leap three yards. The following story respecting one of them is well authenticated. The American Indians are known to be excellent runners, being almost able to equal the best horse in its swiftest course. In order, therefore, to try how well the Bull Frogs could leap, some Swedes laid a wager with a young Indian that he could not overtake one of them, provided it had two leaps beforehand. They carried a Bull Frog, which they had caught in a pond, into a field, and then let it go. The fright, and the Indian who endeavoured to outrun the Frpg, had together such an effect upon the animal, that it made its long leaps across the field as fast as it could. The Indian pursued it with all his might. The noise he made in running, frightened the Frog: it, therefore, redoubled its leaps, and, by that means, reached the pond, which was fixed on as their goal, before the Indian could overtake it. * Were it not for the deeply rooted prejudices which are imbibed, during childhood, against all the animals of the Frog tribe, the beauty of colour, and the elegance of motion of the 29 Green Tree Frog are such, that it would afford delight to every beholder. During the summer months, it resides principally on the upper branches of the trees, where it wanders among the foliage in quest of insects. These it catches with great dexterity, stealing softly towards them, as a cat does towards a mouse, till at a proper distance, when it makes a sudden spring upon them, of frequently more than two feet in height. vlt often suspends itself by its feet, or abdomen, to the under parts of leaves ; and, in this position, remains concealed among the foliage. Although during summer it inhabits the woods, yet, about the end of autumn, it retires to the waters, and lies concealed in a torpid state, in the mud, or under the banks, till the spring. At the return of warm weather, it comes forth, like the rest of its tribe, in order to deposit its spawn in the water. This is done about the end of April, or the beginning of May ; and, as soon as the operation is over, the animalg return to their accustomed haunts in the trees. The offspring continue until the month of August in their tadpole state. During the breeding season, the male inflates his throat in a very surprising manne,| so, in- deed, as to form a tolerably large sphere be- neath his head. He then, also, exerts a very rough croak, that may be heard to a vast dis- tance. Whenever tne of them begins, all that 30 are wiihin'hearing, join in (his discordant cho- rus ; and ihe whole is so Joud, as almost to re- semble the noise of a pack of hounds : this, in still evenings, especially just before rain, when they most exert themselves, has been plainly heard nearly three miles. They are said to be so excellent as barometers, lhat, if kept in? glasses in a room, and supplied with proper food, they will afford a sure presage of changes in the weather. In order to make some observations on the respiration of the Rrptile tribe, Dr. Townsoi> had, among others, some Tree-Frogs, ^He kept them in a window, and appropriated to their use. a bowl of water, in which they lived. The} soon grew quite tame ; and to two. that he had for a considerable time, and were parti- cular favourites, he gave the names of Damon and Muaidora. In the hoi weather, whenever they descended to the floor, they soon became lank and emaciated. In the evening, they sel- dom failed to go into the water, unless the wea. ther was cold and damp ; in which case, they would sometimes remain out for a couple of days. When they were out of the water, if a few drops were thrown upon the board,, they always applied their bodies as close to it as they could: and. from this absorption through the skin, though they were flaccid before, they soon again appeared plump. A Tree-Frog tl-at had not been in water during the night, was 31 weighed, and then immersed; after it hadie- inained about half an hour in the bowl it came out, and was found to have absorbed nearly half its own weight of water. From other experi- ments on the Tree-Frogs, it was discovered, that they frequently absorbed nearly their whole weight of water ; and that, as was clearly proved, and is very remarkable, by the under surface onfy of the body. They will even ab- sorb moisture from wetted blotting-paper. Some- times they throw out water with considerable force from their bodies, to the quantity of a fourth part or more of their owp weight. Both Frogs and Toads will frequently suffer Iheir natural food to remain before them un- touched, yet, on the smallest motion it makes, they instantly seize if. A knowledge of this circumstance, enabled Dr. Townson to feed his favourite Tree-Frog, Musidora, through the winter. Before the flies, which were her usual food, had disappeared in autumn, he collected for her a great quantity, as winter provision. When he laid any of them before her, she took no notice of them ; but the moment he moved them with his breath, she sprung upon and ate them. Once, when flies were scarce, the Doc- tor cut some flesh of a tortoise into small pieces, and moved them by the same means. She seized them, but the instant afterwards rejected them from her tongue. After he had obtained her eonfidenee, she ate, from his fingers,, dead as 32 well as living flies. Frogs will leap at a mov- ing shadow of any small object ; and both Frogs and Toads will soon become sufficiently familiar to sit on the hand, and be carried from one side of the room to the other, in order to catch flies as they settle on the wall. At Gottingen, Dr. Townson made them his guards for keeping these troublesome creatures from his desert of fruit, and they acquitted themselves to his satis- faction. He has even seen the small Tree-Frogs eat humble bees, but this was never done with- out some contest: they are. in general, obliged to reject them, being incommoded by their stings and hairy roughness ; but, in each attempt, the bee is further covered with the viscid matter from the Frog's tongue, and when sufficiently coated with this, it is easily swallowed. A Tree-Fro? was kept by a surgeon in Ger- many, for nearly eight years. He had it in a glass vessel covered with a net, and during the summer he fed it with flies ; but in winter, it probably did not eat at all, as only a few in- sects, with grass and moistened hay, were put to it. During this season, it was lean and ema- ciated ; but in summer, when its favourite food could be had in plenty, it soon again became fat. In the eighth winter, it pined away by de- grees, as was supposed, on account of no in- sects whatever being to be had. As Captain Skedman was sailing up one of the rivers of Surinam, in a canoe, one of the officers who was with him, observed, on the top of a mangrove tree, a battle between a Snake and a Tree-Frog. When the captain first per- ceived them, the head and shoulders of the Frog were in the jaws of the Snake, which was about the size of a large kitchen poker. This creature had its tail twisted round a tough limb of the mangrove ; whilst the Frog, which ap- peared about the size of a man's fist, had laid hold of a twig with his hind-feet, In this posi- tion they were contending, (he one for life, the other for his prey, forming one straight line between the two branches: and thus they conti- ued for some time, apparently stationary, and without a struggle. Still it was hoped that the poor Frog might extricate himself by his exer- tions: but the reverse was the case. The jaws of the snake gradually relaxing, and by their elasticity forming an incredible orifice, the body and fore-legs of the Frog, by little and little, disappeared, till finally nothing more was seen than the hinder feet and claws, which were at last disengaged from the twig, and the poor creature was swallowed whole, by suction, down the throat of his formidable adversan r . He passed some inches down the alimentary canal, and at last stuck, forming a knob or knot, at least six times as thick as the snake, whose jaws and throat immediately contracted, and C 34 fesumed thejr former natu/al shape. The snake being out of r&ftch of musket shot, they could not kill him in order to make further examination, but left him, continuing in the same attitude, motionless, and twisted round the branch. This Frog is a native of various parts of America; of France, Germany, Italy, and many other European countries, but is not found in Great Britain, or Ireland. THE TOAD. AS the toad bears a general resemblance or fi- gure to the frog, so also it resembles that ani- mal in its nature and appetites. Like the frog, the toad is amphibious; like that animal, it lires upon worms and insects, which it seizes by dart- ing out its length of tongue; and in the same manner, also, it crawls about in moist weather. It is not an animal found in Ireland. In some countries, as at Cartbagena, and Porto Bello in America, Toads are so extremely numerous, that, in rainy weather, not only all the marshy ground, but the gardens, courts, and streets, are almost covered with them ; so much so, that many of the inhabitants absurdly be- lieve, that every drop of rain is converted into a Toad. In these countries, this animal is of considerable size, the smallest individuals mea- suring at least six inches in length. If it happen to rain during the night, all the Toads quit their hiding places, and then crawl about in such inconceivable numbers, as almost laterally to touch each other, and to hide the surface of tne/'earth : on such occasions it is impossible to stir out of doors without trampling them under- foot at every step. The female Toads deposi$ thdir spawn early in the spring, ip the form of np^lajG^lilse chains or strings of beautifully transparent ghie, three 36 or four feet in length, inclosing the eggs in a double row throughout. These have the ap- pearance of so many jet-black globules : they are, however, nothing more than the larvae or tadpoles lying in a globular form, which break from their confinement in about a fortnight, and afterwards undergo changes similar to the " tadpoles of the frog. They become complete towards the beginning of autumn, about which time, the young animals are frequently to be eeen in a moi^t summer's evening, crawling up, by myriads, from fenny places into situations somewhat more dry. There, having found out a retreat, or each having termed one for itself, they lead a solitary life, seldom venturing abroad except in moist evenings. At this pe- riod of the year, jthey have a sufficient supply of food, in the snails and worms with which the grass and pathways are then covered. When it i^ irritated, the Toad emits from various parts of its skin, a kind of frothy fluid, which, in our climate, produces no further un- pleasant symptoms than slight inflammation, from iis weakly acrimonious nature. Dogs, on seiz- ing these animals, appear to be effected with a slight swelling in their mouth, accompanied by an increased discharge of saliva. The limpid fluid which the Toad suddenly ejects from hi* body, when o^smrbed, has been ascertained to be perfectly free from any noxious qualities what- ever. It is merely a watery liquor, the con- 37 tents of a peculiar reservoir, that, in case of alarm, appears to be emptied in order to lighten the body, that the animal may the more readily escape. It is its forbidding aspect only that has obtained for the Toad its present unjust charac- ter of being a dangerously poisonous animal, It is persecuted and murdered wherever it ap- pears, on the supposition merely that because it is ugly, it must in consequence be venomous. Its eyes are, however, proverbially beautiful, having a brilliant, reddish^ gold-coloured ins surrounding ihe dark pupil, and forming a strik- ing contrast with the remainder of its body. It is 110 difficult task, singular as it may ap- pear to those who have never attended to this animal, to render it so tame, that it may be taken up into the hand, and carried about a room to catch the flies that alight on the walls, as we have already mentioned in tie account of the Tree-Frog. A correspondent of Mr. Pennant supplied him with some curious particulars re- specting a domestic Toad, which continued in the same place for upwards of thirty-six years. It frequented the steps before the hall-door of a gentleman's house in Devonshire. By being constantly fed, it was rendered so tame as al- ways to come out of its hole in an evening when a candle was brought, and to look up, as if ex- pecting to be carried into the bouse,where it was frequently fed with insects. It appeared most partial to flesh maggots, which wwe kept for c 2 33 it ia bran. It would follow them on the table ? and, when within a proper distance, would fix its eyes and remain motionless for a little while, apparently to prepare for the stroke, which was instantaneous. It threw out its tongue to a great distance, and the insect, stuck by the glutinous matter to its tip, was swallowed by a motion quicker than the eje could follow. Af- ter being kept above thirty-six years, it was at length destroyed by a tame raven, which ont day, seeing it at the mouth of its hole, pulled it out, and so wounded it, that it died in con- sequence. Like the rest of the animals of its tribe, the Toad becomes torpid towards the conclusion of the autumn, and remains so dunng all the win- ter months. The place of its retreat, is either in the cleft cf some rock, under the hollow root of a tree, or amongst the mud at the bottom of stagnant pool*. Of the Toad we have a property recorded, more astonishing than what is mentioned of most other animals, that of continuing alive for cen- turies, enclosed in solid substances. Although we should always be very slow in yielding our belief to what appears marvellous, we have too many respectable authorities for the fact, and too frequent instances of its recurrence, to allow us to doubt its truth. The following are a few of the best authenti- cated of these : In the year 1719, M. Hubert, 39 Professor of Philosophy at Caen, was witness to a livingToad being taken from the solid trunk of an elm tree, It was lodged exactly in the cen- tre, and tilled the whole of the space that con- tained it. The tree was, in every other respect, perfectly firm and sound. Dr. Bradley saw a Toad taken from the trunk of a large oak. In the year 1733, a living Toad was discovered by M. Graburg, in a hard and solid block of stone, which had been dug up in a quarry in Gothland. On being touched with a stick upon the head, he informs us that it contracted its eyes, as if asleep, and, when the stick was re- moved, gradually opened th
