Annual Be port for 1911 of the Consulting Chemist. I^CiS 



A. Feeding Stuffs. 

 1. Linseed Cake. 

 There is nothing special to remark about this. The samples 

 sent me have been uniformly good and up to guarantee. 



2. Cotton Cake. 



Egyptian cotton cakes have l)een, as a rule, good in quality 

 and condition, but with Bombay cakes several woolly and 

 indifferent samples have been met with, some of these showing 

 high percentages of sand. In one instance, where cake had 

 ])een purchased as " from pure Egyptian cotton seed," it was 

 found to be made from " Bombay " seed, and an allowance of 

 10.S. a ton was given. 



A Member submitted to me two samples of cotton cake, 

 "A" costing 51. 12s. Gd. a ton, and guaranteed to contain oil 

 5-82 per cent., albuminoids 21*22 per cent, and "B" costing 

 (jI. 15s. a ton, and guaranteed to contain oil 5*12 per cent, and 

 albuminoids 2487 per cent. The analyses were as follows : — 



'Containing nitrogen . . . 3-49 3-90 



" A," though the cheaper cake, was also the better, 



3. Soya Bean Cake. 

 Several samples of this material have been examined, and 

 in no case has any adulteration been found. 



4. Cocoa-nut Cake. 

 A sample of this gave the following analysis : — 

 Moisture . 

 Oil . 



'Albuminous compounds 

 Carbohydrates, &c. . 

 Woody fibre (celluk)se) 



^Mineral matter (ash). 



8-44 



7-42 



20-68 



56-42 



7-04 



100-00 



'ContaiLing nitrogen ...... 3-31 



^Including sand ....... "54 



This cost 11. lOs. per ton, f.o.r. London, and it is 

 douljtedly a good food, more especially for dairy cattle.
