In the three curara experiments detailed above, the mean secretion per 
kilogramme weight of the animal was 0°351 cc. in Experiment 1, 0-254, ce. in 
Experiment 2, and 0°154 cc. in Experiment 3. In the first case, the secretion — 
was, from some unknown cause, unusually high: the last two coefficients will 
be found a much nearer indication of what is usual in the fasting animal, and 
in subsequent experiments it will be seen that the secretion is requ 
below even the small coefficient in Experiment 3. | 
Undoubtedly the true test of hepatic work is the amount of bile solids 
secreted per unit of body-weight in a unit of time. Any one may calculate 
this from the analyses; but inasmuch as these were not made in every case, and
