IN issuing a second edition of this book originally published under the title of ' Spirit -Gravities ' I have felt it neces- sary to re-write the whole work, in order to bring in an account of the recent in- vestigations, chiefly of Messrs. Squibb, on absolute alcohol. It is not necessary, how- ever, to alter the Tables, as these are sufficiently accurate for all practical pur- poses ; and the percentage of " proof- spirit,^^ so necessary to the public analyst, the brewer, the distiller, and the officers of Excise and Customs, are of coitrse un- affected by the new determinations of the specific gravity of absolute alcohol. Chemical Laboratory, Guy's Hospital, April, 1888. PREFACE TO THE FIEST EDITION. THERE has long been felt a need of a conve- nient Table of Spirit-gravities sufficiently extended to meet the requirements of Public Analysts and others engaged in the analysis of alcoholic liquors. Existing tables are either too incomplete, or, I may add, too inaccurate, to be generally useful. This want I have endeavoured to supply. I trust that the tables which I now place before the public may be found accurate, sufficiently extended, and generally useful. They are founded upon the best accessible dajba, and are preceded by an historical statement rela- tive to spirit-gravities which may, I trust, be found interesting. It should be studied by all those who may do me the honour of consulting my book. THOMAS STEVENSON. Chemical Laboratory, Guy's Hospital, August, 1880. UNIVERSITY ALCOHOL, INTRODUCTION TO THE TABLES. THE determination of the strength of an alcoholic liquid, or, as it is usually termed, an estimation of its " strength," is an operation of great im- portance, and one which the analyst is frequently called upon to perform. The duties levied on spirituous liquors are assessed according to the percentage of alcohol which they are supposed to contain, and hence the Governments of different countries have from time to time sought the aid of chemists and physicists in determining the strengths, expressed in terms of some given standard of alcohol. Very laborious researches have consequently been undertaken ; and yet, even up to this time, the problem is so complex that it has not been altogether successfully solved. Until the law is ascertained, according to which mixtures of alcohol and water contract when mixed, we can only rely upon actual experiments, checked by well-known mathematical methods, for the construction of what are known as " spirit-gravities." At the outset we are met by the initial dim- Till INTRODUCTION. culty, that pure dry alcohol (absolute alcohol : ethyl-alcohol) is a substance procurable only with extreme care and labour ; and, indeed, it was only after the first edition of this book was pub- lished that really pure dry alcohol was obtained by Messrs. Squibb. Even when procured, alcohol is so highly hygroscopic that it rapidly becomes diluted with water when exposed to any atmo- sphere containing aqueous vapour. The best experimental results as to the specific gravity of pure ethyl-alcohol are as follows : Fownes found : Sp. gr. -7938 at 60 Fahr. ; and it is probable, though not certain, that he states the weight of alcohol at 60 compared with the weight of an equal bulk of water, also at 60 F. Hendelejeff found : Sp. gr. -79367 at 15 C. (59 F.), water being taken as unity at its maximum density (4 C.) ; and as he also determined the rate of expansion of alcohol at the given tempe- ratures, his figures, coupled with the best deter- minations of the rates of expansion of water at various temperatures, enable us to calculate the sp. gr. of alcohol at 60 F. to be -79404 com- pared with water, taken as unity, also at 60 F. Dupre and Page found : Sp. gr. -79317 at 15-5 C. (59-9 F.), water at 4 C. being taken as unity ; and as they also ascertained the rate of expansion of alcohol at various temperatures, we can calculate JNTKODUCTIGN. IX the sp. gr. at 60 F. (water at 60 F. = 1) as 79391. Drinkwater found : Sp. gr. -79381 at 60 F. (water at 60 F. = 1). Messrs. Squibb (' Epbemeris,' 1884 ; ; Cbemical News,' 1885, vol. Ixi. pp. 5, 21, 33) bave ob- tained alcobol of a lower specific gravity tban any previous observer bad recorded. Their pro- duct had its specific gravity -79350 at 60 F., com- pared with water taken as unity at the same tem- perature, no other correction for the buoyancy of the air being made than by the use of a counter- poising flask. According to their data, an alcohol of '7938 true sp. gr. at 60 F. would contain 99-9 per cent, of alcohol by weight ; and proof spirit will contain 49-14, and not 49-24, per cent, of alcohol, as calculated by Drinkwater.

It may therefore be stated that alcohol has approximately the following true specific gravi- ties, adopting Squibb 's figure for dry alcohol : Tempera- tures. Water at 4C. = 1. Water at temp, of sp. gr. = l. Water at 60F. = 1. 15J C 60 F 7930 7928 7935 7935 7935 7935 62 F 7919 7928 7926 I have not taken the decimals beyond four places, as the fifth places are unreliable. The percentage of alcohol in a distilled liquid is best determined by observing its specific gravity at a definite temperature. In modern scientific memoirs it is customary to state the specific gra- vity of a liquid, with reference to water taken as INTRODUCTION. XI unity at its point of maximum density (4 C.). In technical work, however, it is better, and customary, to give the apparent specific gravity of a liquid in terms expressing the weight of the liquid, as compared with an equal volume of water taken as unity at the same temperature of 60 F., which is nearly equal to 15-6 C., no allowance being made for the buoyancy of the air. Spirits are, nevertheless, gauged by the hydrometer at 62 F. (16| C.), at which temperature the imperial gallon of water weighs 10 Ibs. The first, and perhaps the most important, scientific inquiry into the best method of deter- mining the strength of spirituous liquors was one undertaken by Blagden and Gilpin on the appli- cation of the English Government, and the results were published in the ' Philosophical Transactions' for the years 1790, 1792, and 1794. Blagden (who devised the experiments) was Secretary, and Gilpin (who carried them out) was Clerk, to the Royal Society of London. The accuracy and fidelity with which the work was executed, and the refinement of the methods employed, have called forth the warmest admiration and praise from those who have taken the pains to examine their work, which would do honour to the more refined science of our day. Fownes's experiments, made more than half a century later, are not for one moment to be compared as to accuracy with the earlier experiments of Gilpin. It has been objected to Gilpin's experiments that absolute alcohol was not employed. In this, and until dry alcohol had been obtained, there was, how- ever, an advantage, in consequence of the greater Xll INTRODUCTION; ease with which a slightly diluted spirit is mani- pulated. Blagden and Gilpin were fully alive to the advisability of levying a duty upon the actual percentage of alcohol contained in any spirit. For an account of Blagden and Gilpin's experi- ments I must refer my readers to the original memoirs of those investigators (Phil. Trans. 1790, p. 321 ; 1792, pp. 425, 439 ; 1794, p. 275). The tables in the ' Transactions ' for 1794 extend over 112 quarto pages, each page containing 16 columns, and each column 50 lines. The work of verifying 270.000 figures must have been most laborious. Yet subsequent observers and calculators have, one and all, vouched for the correctness of the tables. Gilpin's experiments were made by direct weighings, every possible source of error which even the science of the present day points out being avoided, except that the weighings were not reduced to a vacuum ; but this source of error usually affects the fourth decimal in a gravity to the extent of one unit only. The fundamental data of Blagden and Gilpin's tables are as follows : Sp. gr. of alcohol used '82514, reduced by calculation in all tables to an alcohol of '825 sp. gr. at 60 P., water at 60 F. being taken as unity. In the year 1811, Tralles, the Secretary of the Academy of Sciences of Berlin, undertook, at the request of the Prussian Government, an investi- gation with the view of establishing a convenient, just, and accurate mode of determining the rela- tive duties of spirituous liquors, the results of which furnished the basis of the me i.od which INTRODUCTION. Xlll has been carried into operation by Prussia, France, Austria, Belgium, and Sweden. Tralles was led to examine the reports of Blagden and Gilpin, and he pays the highest compliment to the accuracy of their work. " They [the experiments] are," he says, " more than suf- ficiently exact ; " and he determined not to recom- mend to the Prussian Government, as a basis, other experiments less complete and authentic. He remarks, as Berzelius has done, that Blagden and Gilpin had omitted to take into account the air displaced by the liquids weighed. Still, this influence is without importance in practical appli- cation, for the specific gravity of an ordinary spirit reduced to a vacuum is scarcely changed by '0001. Since Blagden and Gilpin give specific gravities to 00001, their fifth places of decimals are unre- liable ; their fourth decimal places may be correct within one unit. In Tralles's day no chemist had been able to produce alcohol of less density than that obtained by Lowitz ; and Tralles took this as his standard alcohol. It had the following specific gravity : 791 at 15 E. (68 F.), water = 1' at the same temperature. If this sp. gr. be compared with that of water at 60 F., we get for Tralles's alcohol 78962 at 68 F., water at 60 F. = 1, or -7942 at 60, water being unity at the same temperature. Tralles, however, appears as Gilbert says, purposely to have assumed a smaller rate of expansion than he himself found for his alcohol by experiment ; and, owing to this error, he takes the specific gravity of his alcohol at XIV INTRODUCTION. 60 as -7946, compared with water taken as unity at 60, or '7939, compared with water at its point of maximum density (4 C.). The sp. gr. -7946, adopted by Tralles, is often referred to as a well- determined result ; but it is not so, and its accu- racy appears to be more than doubtful. Tralles having determined to adopt the work of Gilpin, it became necessary to determine how much water is contained in alcohol of the specific gravity -825 (Gilpin's alcohol). By a series of experiments this was found to be 92-6 per cent, of Tralles's alcohol by volume, or 89-2 per cent, by weight. The true percentage of absolute alcohol in Gilpin's alcohol is 8 8' 9 6 per cent, by weight, or 92-49 per cent, by volume. The table of Tralles, found in many text- books, gives in one column the specific gravities at 60 P. (water at 4 C. = 1), and in another the per- centages of alcohol by volume. The range is from pure water, sp. gr. -9991, to alcohol, sp. gr. '7939. Tralles did not publish the experiments from which he deduced his conclusion that Gilpin's alcohol contained 89'2 of Tralles's alcohol ; and Gilbert says that the data were not among the papers confided to him. Dividing Tralles's gravi- ties by '9991, to make them, comparable with Gilpin's, and assuming that Tralles's alcohol con- 88-96 tained 100 x-gy-^ =99-73 per cent, of alcohol by weight or 99'85 per cent, by volume, I com- pared Tralles's table with Gilpin's at the several points at which their specific gravities are com- parable; and I find the annexed results at the points where the specific gravities are practically coincident.
