214 Report or CHEmist oF New YorRK EXPERIMENT STATION. 
seems to be true for our trials, and we have further found that 
certain nitrogenous foods have produced the greatest amount of 
butter fat. 7 
We are aware that many trials with a large number of animals 
are necessary to establish a single fact, where the conditions are of 
such a complex nature as we have to deal with in all physiological 
questions and for that reason we ask that judgment may not be 
passed upon these results until further experiments may enable 
us to study more fully this question, and the results of other inyes- 
tigators be secured to verify our own results or to point out the — 
source of our error.
