A New and Useful Invention for Light very beneficial by Sea and Land.  
AN Experiment thereof having been made in his late Majesty's presence at Whitehall, He was graciously pleased to approve of it so well, as not only highly to commend it, but to grant his Letters Patents for the Promotion and Encouragement of the same.  
Now the several Uses of this Invention being almost innumerable, it was thought sit by the Patentee and others who are concerned with him, to demonstrate some part thereof in the City of London on Tuesday Night, being the eighth Day of December last passed, where several of the most Eminent Citizens, and other Persons of good Quality, were pleased to give their Approbations. And being well approved of, it is thought necessary to particularise several of the uses of the said Invention, and the great advantages that may accrue to the said City and other Places thereby, if encouraged.  
I. It will be of extraordinary use for Ships, to be used instead of their common Lanterns, first in respect of their durableness, being so durable, that nothing ever of that kind is to be compared to it: secondly in respect to their great 〈…〉 crease of Light, giving ten times a better Light, than any Lanterns now in 〈…〉 and will burn with great clearness from Sunsetting to Sunrising, and the ro 〈…〉 of the Ship will not disorder them. And they are also contrived for the P 〈…〉 and to use between Decks and in the Hold, and are secure from the dar 〈…〉 firing Powder and other Combustible Materials, giving such Light, ●ha 〈…〉 Person may read or do any business there, where Light is required.  
II. This Invention will be of very great use for Light-Houses, where 〈…〉 will appear much more conspicuous, less troublesome and be cheap 〈…〉 Coal-fires now in use.  
III. Those Lucidaries will be of extraordinary advantage in 〈…〉 of Light to very great distances, and will be secure against Dar 〈…〉 rise, and put out the Lights they now use.  
IV. They will be of excellent use to enlighten the Streets of 〈…〉 where they may be kept constantly burning from the Hour 〈…〉 Twelve, being three Hours longer than the Lights now in u 〈…〉 and at as small a Charge as the Inhabitants are now at, and givi 〈…〉 Light; also they will very much ease and take off that trouble 〈…〉 tants of the City of London (who are obliged to hang or put o 〈…〉 a Light) by committing them to the care of such Persons as sha' 〈…〉 for that purpose: And they will be of very great use to Shops that 〈…〉 and will much encourage People to go out and by, who keep at home 〈…〉 for want of being better accommodated with Light; and many abuses 〈…〉 mitted upon Passengers for want thereof, as by frequent Examples are 〈…〉 And if the Inhabitants shall think fit to continue the Lights from twelve 〈…〉 the Morning, and consider the Charge, they may receive these further add 〈…〉 by them. First they will be of great benefit in case of Fire. Secondly th' 〈…〉 be of great Service to their Watches, whereby Burglaries and House-breaking 〈…〉 be much better prevented. Thirdly they will also be of great use to that Pr 〈…〉 on for cleansing of the Streets in the Nighttime, whereby the Inhabitan 〈…〉 be very much freed from those Nauceous Smells that arise from the Filled 〈…〉 Soil carried through the Streets in the Daytime, and those Persons that will 〈…〉 employed so to cleanse the Streets in the Night will be very serviceable in ca 〈…〉 Fire, and will much prevent House-breaking, as aforesaid.  
V. They will be of great use in Universities, Inns of Court and Chancery, an● all public Halls, Offices, Brewhouses, Landing-places, Wharves, Warehouses Sellars, Stables, and all other great Places whatsoever.  
If any Person have a desire to use these Lucidaries the Undertakers will give the Attendance daily, from the Hours of Eleven till One, at Lawrences' Coffee-hous 〈…〉 in Freeman's Court Cornhill, where they may make Agreements upon such Reasonable Terms as will, we hope, be well approved on by such as are willing to encourage an Invention of so great use.
