cent., and the fat, so far as it can be meclianically separa- 

 ted, 10 to 40 per cent. It is to be noted, however, that the 

 fresh bones contain 11 to 14 per cent, of water, and the 

 muscles from 00 to over 75 per cent. The average of the 

 results of numerous investigations made on the various 

 farm animals gives them approximately the following 

 composition : 



Bones 9 per cent. 



Flesh and tendons 40 ** 



Mechanically separable fat 24 '' 



The remaining 27 per cent, comprises the blood, hide and 

 hair, entrails, and the contents of stomach and intestines. 

 Fuller details regarding the proportions of the various 

 parts in lean and fat animals of various kinds are to be 

 found in the Appendix. 



It should be added that the volume and weight of the 

 contents of the stomach and intestines are very various, 

 according to whether the animal has received a more or 

 less bulky fodder. For example, in some investigations 

 made by E. v. Wolff, in Ilohenheim, with sheep, the fol- 

 lowing averages were obtained :
