ACIDULATED WATEKS 



the difference between water drawn from th<; 

 bottom of the well, and water taken from th 

 furface. And this is the other reafon to \vhich 

 1 above alluded, for drawing water for drinking 

 rather from the bottom than the furface of the 

 well. This may be done with a veflcl in the 

 fhnpe of an inverted cone, made of tin or pure 

 lilver, truncated on the under part, and clofed 

 with a folid bottom, fo contrived that it may 

 rife upon a hinge, when the vcllel is immerf- 

 cd, and may be again (hut by the weight of the 

 water when it h taken up. With this veilel 

 fixed to a long wooden handle, water may be 

 taken up from any depth. A fmall iron rod 

 may be fixed to the brim of the veilel, in order 

 to clear the bottom of the well, and the water 

 may run out from the narrow part of the cone 

 into a different Veilel. This mode of drawing 

 the water will be adapted, I prefume, by all 

 v/ho willi to have it as cold and as flrongly iiru 

 prcgnutcdjwith hepatic air aspoilible ; although 

 [ mean not to aflert that it is of no uie when 

 drunk in the common way. 



This mineral water appears to be lighter than 

 common. water : but not having an hydroflatic 

 balance at hand, I could not determine its f pa- 

 cific gravity. A pint of it weighed. an hund- 

 red and ninety four drachms.
