In making the theoretical combinations I found that there is not 
enough mineral matter with which to combine the potassium, so that 
it must be associated with the organic matter. 
The water has a very disagreeable odor, an intense brown color 
and a heavy sediment. I have never encountered a water anywhere 
similar to this one and I am wondering if the peculiarity is not due 
to an unclean jug in which cider or some such liquid had been kept.

The two water analyses which you sent me are not easy to inter- 
pret, for I do not know how the samples were collected and shipped, 
nor how the analyses were made and calculated. The sodium and 
chlorine are doubtless of oceanic origin, in part if not wholly cyclic, 
that is, brought down in rain over the drainage basin of the lake. 
The other constituents, except the organic matter, came from the 
feldspars and ferromagnesian minerals of the granite. The apparent 
excess of potassium may be held in equilibrium with silica, although 
the balance between the two is not very close. How much of the 
trouble is due to analytical errors, which are never wholly avoidable, 
I will not attempt to say. I doubt, however, that any organic salt
