Royal Society , to Daniel Peter Layard, M. D. 
Phyfcian to Her Royal Highnefs the Prince fs Dowager 
of Wales, Member of the Royal College of Phyfcians 
in London, and of the Royal Societies of London

Somerfham Water . 
Dear Sir, 
F R O M your very accurate account of the Angu- 
lar mineral water, found at Somerfham, in 
Iluntingdonfhire, and its falutary effe&s in many oh- 
ftinate dileafes, it appears to be highly deferving the 
attention of the public. I, therefore, agreed with 
plealure to your propofal of repeating the experi- 
menrs here, which you had formerly made at the 
ipring head, and at Huntingdon ; and adding fuch 
as you were obliged to omit in the country for want 
of a proper apparatus. 
As you intend to oblige the public with an account 
of the former, to which our repeated trials here 
were perfectly conformable, I final 1 confine myfelf in 
the following narrative, principally to the latter, at 
which you a Aided in my laboratory. 
Experiments on the Somerfam Water. 
The water ieemed clear in the bottles, though 
there was fome Pediment at the bottom. It was 
clear and bright when poured into a glafs, but did 
not fparkle nor emit air bubbles for a confiderable 
time
