368 WHITELEY: ANALYSIS OF THE KISSEXGEN WATER. 
less than in 1879, is more than before; of Silica there is twice as 
much as in 1879, or eig-ht times what it was in 1854; whilst the 
Chlorine is lower than ever. 
I have also been able accurately to estimate the Bromine, thoug-h 
unable to find a trace of Iodine. 
You will please to bear in mind that in these comparisons I 
have been dealing with differences always in proportion to the total 
solid matter, whilst the figures in the table give yon the real 
difference in parts per gallon. 
To place these ratios more clearly : —

If I am asked for the reason of these strange variations, I can 
only give an hypothetical answer. 
Mr. McNeill (the present lessee of the gardens, who has helped 
me in these investigations by every means in his power) says the 
water often varies considerably on two consecutive days, and yet 
in an opposite manner, for example : — one day at 7 o'clock it is 
weak, and at 8 o'clock is strong ; and perhaps next day it is weak 
at 8 o'clock and strong at 7 o'clock. And through him I was able 
to see a report of Mr. Davis's about this water, to which I am kindly 
allowed to refer. 
On examining the well in March, 1880, he found no less than 
five different sources of water, all of which combine to form the 
Kissengen water ; the strongest of these had 930 grs. per gallon 
total sohds, whilst the weakest had only 191 grs. with specific 
gravities of 1-0098 and 1*0018 respectively. Also the water taken 
from different depths of the well in which it accumulates, differs 
considerably in strength. 
Taking these facts into consideration, it seems to me that we 
cannot wonder at the differences in the analyses, as so much seems 
to depend not only on the amount of water in the well, but also on 
the relative rate at which these various springs are flowing at 
the time.
