ON THE SECRETION OF UEINE.

a great increase occurs in the total quantity of urine, while at the 

 same time the elimination of N. is diminishing. In some of the experi- 

 ments, though not shown in this table, the total N. fell below the 

 average, while the total quantity of urine rose much above the average. 



As tested by the specific gravity, the other solid constituents of the 

 urine did not seem to vary. 



Where no remark regarding food is made, it must be understood to 

 have been all consumed. 



The following tables give the results of a single experiment with two 

 diflPerent cats : — 



Table II.— CW. 



Table III.— Cai. 



These tables show results similar to table I. After injection the 

 nitrogen rises in spite of the greatly diminished consumption of food, 

 while the total urine falls. Two or three days later the total urine rises, 

 while the N. falls. At the same time the ability of the animal to take 

 the usual quantity of food is returning. The changes that have been in- 

 dicated are markedly shown in table II. 



A series of experiments was conducted on rabbits. While supplying 

 no results contradicting any of those mentioned, none confirming them to 

 a. satisfactory extent was obtained. This seemed to be dae to the marked
