 of that benevolent inftitution which has been the mean, in 

 the hand of Providence, of averting the tear of forrow from 

 the eye, and inexpreflible an^uifli from the heart, of many 

 individuals who daily implore that the richeft bleflfing» of 

 Heaven may be fliowered down upon the HumanJ 

 Society. The apparatus feems fo well contrived in all 

 its parts, as ahnoft to preclude the poffibility of improving 

 it : yet there can be little doubt that by the ingenuity of 

 Britifli artifts it might be Amplified a little, and produced at. 

 fo cheap a rate that the funds of the Society might be able 

 to add fuch machines to their other apparatus for faving 

 people from drowning. If fuch machines were depofited at 

 the places where accidents of this kind moft ufually occur, 

 and fome perfons in the neighbourhood inuru&cd in the uic

 refcued from death ! How infinitely preferable would this be 

 to dragging, and how much more certain in its refult, fince 

 the diver, when under water, could look round him for his 

 object, and proceed directly to the fpot ! For fuch a pur- 

 pofe it would be advifablc to make the machine fo large 

 that it would require an extra weight, more than equivalent 

 to that of a man's body in water, to fink it : the diver, by un-

 cend to the furiace of the water with the patient in his arms.
