THE EARTHY AND ALKALINE PHOSPHATES.

The general conclusions are : — 
1. That acute affections of nervous substance, organic and functional, are the only 
diseases in which an excess of phosphatic salts appears in the urine. In acute inflam- 
mation of the brain, the amount of phosphates seems to be proportional to the inten- 
sity of the inflammation. In some states of violent delirium the amount of phos- 
phates may also be proportional to the delirium. 
2. That in a large class of functional diseases of the brain, of which delirium tremens 
presents the most marked examples, the amount of phosphates is most remarkably 
diminished. 
3. That no chronic diseases whatever show any marked excess in the total quantity 
of phosphatic salts secreted, at least as far as this mode of analysis is conclusive. One 
case of mollities ossium formed the only exception to these rules.
