But one sample (of linseed cake) contained less than 10 per 

 cent, of fat ; but in that one the amount was only 3.15 per 

 cent., while that of the protein was 39.92 per cent., show- 

 ing that the sample had been extracted in some manner. 

 Cotton-seed cake, it will be seen, is considei'ably richer in 

 protein and fat and poorer in nitrogen-free extract than 

 linseed cake, and must have a correspondingly higher 

 feeding value. 



Palm-nut cake contains less albuminoids and more nitro- 

 gen-free extract than linseed or cotton-seed cake, while the 

 percentage of fat is about the sam6. It forms an excel- 

 lent fodder, being very palatable and producing excellent 

 results. 



Digestibility. — The numbers given in the Appendix 

 for the digestibility of linseed cake are the avei'age results 

 of numerous experiments on sheep, goats, and oxen, made 

 in Hohenheim, llalle, and Mockern, respectively, and 

 agreeing well with each other. 



The digestibility of cotton-seed cake has been tested in 

 experiments on sheep in Ilohenheim. The material used 

 came from Egypt, and was of poor quality compared with 

 that sold in our markets. It contained numerous fragments 

 of leathery pods, which brought the amount of crude jfibre 

 up to 27.61 per cent., while it contained only 26.24 per 

 cent, of protein. It seems somewhat doubtful whether
