The above reaction explains the presence of acid sodium phosphate in urine. To account for the forma- tion of free hydrochloric acid in the gastric juice, sodium chloride is substituted for the neutral sodium phosphate, the decomposition in this case being Acid Sodium Sodium Normal Sodium Hydrochloric Carbonate.

Practically, it matters little which view we adopt, since all the salts named are present in the blood; the itaportant fact being, that out of the body a weak electrical current will separate the acid from its base. Whether the decomposition occurring in the body is due to the same agency must for the present remain a matter of conjecture. Still, the experiment of Professor Dubois Eeymond, made with an extremely sensitive galvanometer, which shows that there are no two parts of the body whose electrical condition is precisely the same, and that the differences between them are greater * ' Zeitschrift f.
