fcls made of the fame fort of tinned copper with which the 

 tanks were lined. I am. Sir, 



T.y J. 7 Your obedient fervant,

A certificate from captain William Bolton, commander of 

 the faid veflel, dated Shcernefs, 28th of June 1800, accom- 

 panied this letter, Hating, that the water delivered to the 

 Society was taken from a tank holding about fcven hundred 

 gallons, and which his predecelTor, captain Portlock, had 

 informed him had been poured into this tank in December 

 3796, except about thirtv gallons added in 1798, and had 

 remained good duriuij the whole time. 



The fi'i^natures to the above accounts were certified on the 

 sSthof June iSoo, by the Eev. C. Thee, minifter of Shecr- 

 nefs. 



In a letter dated January 27, general Bentham alfo ftates, 

 that the water which had been preferved fvvect on board his 

 majeftv's Hoops Arrow and Dart, and of which he had fent 

 fpecimcns to the Society, was taken from the well at the 

 kind's brewhoufe at Weevil, from whence (hips of war lying 

 at or near Portfniouth are ufuallv fupplied with water for their 

 fea ftore, as well as for prefent ufe. 



III. Defcription of a Machine for raijtng Water. By Mr, 

 H. Sarjeant, of IVhitehaveny in Cumberland*. 



I SIR, 

 AM fonfible that the little engine, a drawing of which 

 accompanies tliis letter, can lav no great claim to novelty in 

 its principle ; neverthelefs it is refpeftfully fubmitted to the 

 conlldcration of the Society, how far its fimplicity, and cheap- 

 nefs of conftruftion, may render it worthy of their attention, 

 with a view to its being more generally known, and ufed in 

 iimilar cafes. 



Irton hall, the feat of E. L. Irton, efq. is fituated on an 

 afcent of fixty or fixty-one feet peq^endicular height; at the 

 foot of which, at the diftance of about 140 yards from the 

 offices, runs a fmall dream of water. The objcft was to 

 raife this to the houfe for domedic purpofes. 



To this end a dam was made at a (liort diftance above, fo 

 as to caufe a fall of about four feet ; and the water was 

 brought by a wooden trough, into which was infcrted a piece 

 of tw^o-inch leaden pipe, a part of which is fecn at A. (fig. i. , 

 Plate n.)
