wate^weie analysed by Dr. Christie of the 80th regipmnty with'
some other medical gentlemen belonging to the garrison.,, ;-The
result of this analysis, with a copy of-which I was fayppreid’,, is
as fellows:
The h'ot-wells of Cannia are six in number,.;: andrp£ different
degrees of heat. They all, however, evidentlyk^mmunicatei jfor
tlie water in all of them is a t an equal distance-from ^ § .^ u r-
4-faceN o£ the ground; and a, body immersed tfcem
raises the height of the water in thé o th e r...
, As the water also from all the six „wells" exhibits the same
phenomena, there can be little doubt that they all. proceed ffrcan
the same .spring.
Upon examining the heat of the different wells with great
attention, it was found, they varied from 98 to 1Ö6* degrees of
Earenheit’s thermometer, nearly in. proportion |ó their different
depths.
Bubbles of; air are seen to rise fróm the bottom of all the
wells, and it was therefore conceived that the water..might bp
acidulous, and impregnated with carbonic acid gas.
I t was found, however, that the water did ‘not, sparkle in a
glass . more than common water, nor did it turn a delicate
vegetable colour red ; and upon filling a large case bottle with
