show a variation of seven parts, whilst the Hetling Pump water 
was the most constant, giving only two parts per million. 
The Cross Baths are not noticed in this table, as the only get- 
at-able source was daily contaminated by people bathing there ; 
but its figure for Chlorine is comparatively high, being 280, and 
this was determined on the only opportunity I had of getting at 
the water in a state of purity. 
You will readily perceive from the result of the analysis which 
I have laid before you, that the waters of the different springs 
undoubtedly come from the same source in the earth. We may 
justly suppose that the spring travels in an easterly direction, 
from the fact that the waters give their greatest strength at the 
Hetling and Cross Baths, while at the other two Baths they appear 
to lose somewhat of their solid contents. It may possibly be 
argued that the reverse is the case ; but it must be remembered 
that at the Hetling Pump we get the greatest heat, at the 
same time the water shows a greater amount of Calcium and 
Sulphuric Acid. This, of course, is simply my opinion formed 
from my own observations ; the geological formation of the strata 
through which the spring passes would have everything to do 
_ with its solid contents, but that is a point I am not prepared to 
enter into at the present time, still I should be very glad to hear 
the opinion of some of the members of this Club on the subject. 
We may deduce three facts from these analyses ; Ist, that the 
waters from the Hetling and Cross Baths are stronger in their 
mineral constituents than those of the Roman and King’s Baths, 
2ndly, that these waters show a daily variation, which, though 
not large, may yet be distinctly recognised, a point not noticed by 
_ other analytical chemists. 3rdly, that the mineral water from the 
_ chief drinking source in this town does not contain the amount of 
iron which it might, and which the original water holds in 
solution. I refer to the fountain in the Grand Pump Room. 
In conclusion I must thank Dr. Falconer for his kindness in 
_ procuring me access to the waters of the King’s Bath.
