Among the interesting conclusions which may be drawn from 

 these investigations, we will simply refer to the observation which 

 had earlier been made by Schlossberger, that the amount of nitrogen 

 in muscular fibre does not essentially differ throughout the whole 

 animal kingdom. The flesh offish contains the same absolute 

 amount of nutrient matter as that of the higher animals ; oysters 

 on the contrary, in opposition to the general view, contain far less, 

 and hence the difference between the absolute amount of nutrient 

 matter and the amount of easily digestible matter is most clearly 

 shown. 



We need, however, scarcely observe, that we cannot judge 

 directly from the amount of nitrogen contained in animal nutrient 

 matters regarding their direct value in the reproduction of the 

 blood and tissues. For the nitrogen, which is found, depends in 

 part upon the gelatigenous matters of the animal nutrient sub- 

 stances; it is, however, still very doubtful whether the gelatinous 

 substances can contribute anything towards the reproduction of 

 the tissues, although it may at least be seen with certainty from
