Composition of goat manure. — A sample of goat manure was analyzer! 

 and found to contain: Nitrogen, 0.74 per cent (0.042 per cent in the 

 form of ammonia); phosphoric acid, 0.24 per cent, and potash, 0.17 per 

 cent, indicating- a composition and value similar to sheep manure. 



Alkaloids in distillery slump, — A sample of distillery slump was found 

 to contain 6 decigrams solaniu and 1.5 decigrams solauidin salts per liter 

 of slump ; also 0.4 volume per cent of alcohol, a small trace of copper, 

 and an alkaloid substance, most likely a ptomaine. An animal con- 

 suming 30 liters of slump j)er day would thus take in 18 gm. of solanin 

 and 4.5 gm. solanidin salts daily. — f. w. woll. 



Report of agricultural chemical v/ork for the Royal Agricul- 

 tural Society (Norv/ay) in 1895, V. Stein {Tidsslcr. Landokon., 14 

 (1895), pp. 618-635). — The author describes the chemical control work 

 on feeding stuffs, fertilizers, and dairy products performed during 1895 

 for this society. Of the 503 samples of feeding stuft's analyzed there 

 were 191 samples of rape-seed cake, 113 of wheat bran, 70 of sunflower- 

 seed cake, 33 of cotton-seed meal, 28 of linseed cake, 6 of cocoa cake, 

 and 6 of palm-nut cake. The 1,520 samples of fertilizers examined 

 included 817 samples of superphosphates, 238 of mixed fertilizers, 152 

 of potash salts, 143 of Thomas phosphate, 41 of bone meal, and 42 of 

 Chile saltpeter. The 3,867 samples of dairy products included 1,899 

 samples of milk, 1,920 of butter, and 46 of cheese. 



All samples of feeding stuffs analyzed were examined microscopically 

 to ascertain their purity. The following table gives the average com- 

 position of the common feeding stuffs analyzed in 1893-94 which micro- 

 scoi:>ic examination proved to be free from foreign impurities :

1 Sunflower-seed cake is divided into two groups according to the cembined content of nitrogenous 

 substances and fat, viz, I, 50 per cent and above, and II, below 50 jier cent.
