58 Mr. latham’s Account of , Sec. 
As to the quantity of water taken off, I find it to 
amount, upon the neared: calculation, to twenty-four 
pints at each operation ; for though the firft time pro- 
duced only twelve pints, and in feveral of the latter ope- 
rations the quantity fell fhort of twenty-four pints, yet I 
may venture to Hate it at lead: at twenty-four pints or 
three gallons on an average, as in many of the operations 
I took off from twenty-eight to thirty pints. The number 
of times I tapped her was in all 155, which brings out 
in the whole 3720 pints, being 465 gallons, not far 
lhort of feven hogfheads and an half. As to the authen- 
ticity of the whole, your connexions with the family, 
and frequent opportunities of feeing this young lady 
during her illnefs, will put it beyond a doubt. I have 
therefore no more to add, than my wiflr that the cafe 
may prove acceptable to the Society. 
I am, See.
