cotton cake, we may expectsomething much more decided 

 from the improved decorticated cake. Dr. Voelcker 

 has recently made analj'ses of seven different specimens, 

 the results of which wero given in the 19th vol. 

 of tlie Transactions of the Royal Agricultural 

 Society. And as this book may not be accessible to 

 all our readers, we give it herewith as follows : — 



These specimens were all decorticated thin cake. 



The seven specimens averaged as follows in com- 

 position : — 



100.00 

 Nitrogen 6.58 



Since the above analyses were made, Mr. J. C. Nes- 

 bit has tried three samples of decorticated cotton-seed 

 cake yielding the following results :

 It will be seen from the foregoing analysis that the 

 composition of specimens of cotton cake differ in their 

 constituents as to amount ; but in the decorticated 

 cake this difference is not material enough to affect the 

 value of the article. Not so, however, the ordinary 



cake, or that with the husk in it. Certain samples have 

 been imported in which, there is every reason to be- 

 lieve, a large portion of the husk from the decorticated 

 cake has been worked up. Some of this cake A'as pur- 

 chased by Mr. John Fryer, of Chatteris, who gave itto 

 his cattle. One of them died ; and upon opening it 

 after death, the passages of the stomach were com- 

 pletely stufied and stopped up with the husk of the 

 cotton-seed cake. The farmers must therefore be 

 cautious, before purchasing the ordinary cake, to ascer- 

 tain by analysis the proportion of husk it contains, it 

 being wholly indigestible, and consequently injurious, 

 and even dangerous to cattle in excess. 



We have still to speak of the value of cotton-seed 

 cake in respect to the manure produced from its use in 

 fattening cattle and other animals. Mr. J. B. Lawes 

 has investigated this point. In the Mark-lane 

 Express of the 23rd of January in the present year is 

 a letter from him, in which is given the comparative 

 value of the manure from the consumption of twenty- 

 five articles of food. In order to render this account 

 as complete as possible, we again insert the results of 

 his investigations : —

We conclude with the observations of Professor 



Voelcker on the result of a recent analysis of thin decor- 

 ticated American cotton seed cake lately imported :— 



'< 1st. The proportion of oil in all the specimens is 



higher than in the best linseed cake, in which it is 

 rarely more than 12 per cent., and 10 per cent, may 

 be taken as an average. As a supplier of food, cotton 

 cake is therefore superior to linseed cake. '2nd.— The 

 amount of oil in the several specimens differs to the 

 extent of ^^ per cent.— say from No. 7, 13.50 to No. 2, 

 ly.lO, 3rd.— Decorticated cake contains a very high
