of sugar cane secui-ed from hajJiaHse. It is c.laimetl that this material is dry and has 

 an advantage over molasses, sinc(^ it can l)e readily handled and shipped.

 feeding stuffs. 



Poppies and poppy-seed cake, F. M.vcn {iMudir. Verx. Stat., .57 {1902), No.

 value of poppy seed and poppy-seed cake are discussed and proximate and ash 

 analyses are reported. The author summarizes the results ol)tained by many pre- 

 vious investigators. 



Sugar cane as a fodder for stock, F. B. Guthrie {Agr. Gaz. Nciv South Wale.% 

 13 {1902), No. 10, p. 1054). — Analyses are reported of whole sugar cane, sugar-cane 

 tops, and a mixture of equal parts of the two. These analyses follow:

Succus entericus and pancreatic digestion, E. Pozerski {Thesis, Paris, 1902; 

 (dts. in. British Mid. Jonr., 1902, No. 2179, Epit., p. 52). — From experiments with rab- 

 bits and dogs the following conclusions regarding the effect of the intestinal juice 

 upon the amylolytic action of the pancreatic and salivary secretions were drawn: 

 "There exists in the succus entericus a substance which renders active (or aids the 

 action of) the amylose ferment of the pancreatic; secretion. This substance has a 

 similar adjuvant action on the amylose of the saliva and of Aspergillus niger. iVIacera- 

 tion of lymphoid glands, especially the mesenteric glands and spleen, and of leuco- 

 cytes gives rise to a substance which has similar activity in aiding the amylolytic 

 ferment of the pancreatic juice. This substance has nothing in common with the 

 trypsin of the pancreatic juice. It is not itself a diastatic ferment.- The adjuvant 

 action of this substance is probably due to the presence in it of certain salts and pro- 

 teid materials, whose precise composition, however, has not yet been ascertained. 

 This substance is present in the succus entericms; but as to its exact origin (whether 

 secreted by the mucosa or derived from leucocytes which have passed into the ali- 

 mentary canal in the processes of digestion) there is still some tloubt."

T}}e food of maintenance (pp. 89-97).— This subject was studied in a preliminary 

 test made in 189-1 with 2 cows, in a second test made in 1896-97 with 2 cows, and in 

 a third test made in 1897-98 with 3 cows. On an average daily ration of 11.38 lbs. of
