The nutritive values of different albuminoid bodies, S. Gabriel (Journ. f. 

 Landiv., 37, jj^jj. 175-197). — The question whether a difference in the com- 

 position of albuminoid bodies is accompanied by a difference in nutri- 

 tive value is one of importance and one upon which a variety of views 

 have been expressed. Liebig considered the nitrogen as the measure of 

 the food value of albuminoids, their nutritive value increasing with the 

 increase of the proportion of nitrogen. Eitthausen,* on the contrary, 

 measured their value for food by the content of carbon. 



The number of experiments on this question is quite limited. Those 

 of Panumt and Heiberg on the one hand, and of Haubner | and Hofif- 

 meister § on the other, are contradictory and lead to no very conclusive 

 results. 



Feeding experiments by H. Weiske, || with two sheep, in which the 

 effect of nitrogen from vegetable sources (hay and ground oats) was com- 

 pared in separate periods with that from an animal source (dried ground 

 fish), led to the conclusion that the nitrogenous substances of ground 

 fish were capable of replacing like quantities of albuminoid materials 

 from vegetable sources. 



Likewise, experiments by E. v. Wolff,^ in which two lots of pigs were 

 fed exactly alike, except that one lot received albuminoids from a vege- 

 table source (peas) and the other a like quantity from an animal source 

 (ground meat), indicated like food values for the albuminoids from the 

 two sources, the gains being the same in the two lots. Owing to certain 

 disturbing influences the results of this trial are not considered as alto- 

 gether conclusive. The results of experiments by Kutgers ** on himself 

 indicated the same values for albuminoids from animal as from vege- 

 table sources, although this experiment is not considered as entirely 

 reliable, the data being somewhat deficient. Fotthaft tt concluded from
