In reference to the Moeckern experiments on the production — 
of milk fat by cows, Dr. Armsby says: ‘“ whether the fat of the 
body took part in the milk production, as isso often the case with 
milk cows, even when,well fed, could only have been decided — 
might be adduced.” 4 4 
Again he says, “a dog weighing about twenty kilogrammes, 
after thirty days of fasting, was fed for five days with the great- 
est possible quantities of pure fat, of which on an average of 370.8 ; 
grammes daily were digested. In the body of the animal, which _ 
was killed at the end of the experiment, 1352.7 grammes, of fat 
were found on the various organs, instead of the 150 grammes, 
which according to other investigations, was the greatest amount 
that could have been present in the body after thirty day’s fast- 
ing, so that in this case about 250 grammes daily of the fat of <2 
the food remained undestroyed and were deposited within the 
body. In numerous other experiments on dogs, too, with a more 
normal food of meat and fat, and with the help of the 
respiration apparatus, the fact has been confirmed that often a very 
considerable part of the fat of the food may be retained in the "4 
body.” 
Again he says, “the fat in the fodder of the herbivora is not 
prevented from contributing directly to the deposition of fat in 
the body, since most of the vegetable fats are very similar in their 
composition and properties to the animal fats.” Why could he — 
not have said that they were identical? In what does the vegeta- 
ble oils, as olein, stearine, palmatine, differ from these same phe ee 
which are found in the animal body ? ‘ coe
