The average coefficient of digestibility of the fat of the ration, of 

 which over 97 per cent was goose fat, was 94.2 per cent, while 68.5 per 

 cent of the protein and 96.5 per cent of the carbohydrate were 

 retained in the body. Making allowance for the metabolic products 

 and undigested fat (if any) from the basal ration occurring in the 

 ether extract of the feces, the digestibility of goose fat becomes 

 95.2 per cent. In practically all the tests the subjects reported 

 that the diet had a somewhat laxative effect; in fact, in two or three 

 instances this was so pronounced that it was impossible to complete 

 the test period and to secure the required experimental data. 

 Since an average amount of 95 grams of goose fat was eaten daily, 

 however, without any very pronounced physiological disturbances, 

 it is reasonable to assume that goose fat in smaller amounts would 

 not differ in such respects from other well-known fats, a conclusion 

 borne out by the fact that users of the fat in other countries have 

 found it not only wholesome but desirable. 



BRISKET FAT. 



In a previous paper ' a study of the digestibility of beef kidney 

 was reported in comparison with mutton kidney fat and pork kidney 

 fat (lard), which showed differences in digestibility corresponding to 

 the w^ell-known chemical and physical differences between those fats.
