 (1897), No. 3, pp. G73-683). — Tests were made to determine the feeding value of 

 cotton-seed hulls, corn, and bran, with bay and straw, using 80 sheep divided into 8 

 equal lots. The test lasted from December 23 until April 4. The gains in weight 

 were recorded. On this basis the best results were obtained with a ration of corn

Do coffeon and caffein-free coffee surrogates produce the effect of coffee? 

 K. B. Lehmann and F.Wilhelm (Arch. Hyg., 23 (1898), No. 4, pp. 310-326).— Coffeon 

 is a product obtained by condensing the material volatilized when coffee is roasted. 

 Experiments were made with man with coffee, caffein, coffeon, coffee distillate, an 

 ether extract of coffee, coffee surrogates, fig coffee, and chicory. The principal con- 

 clusions follow: The pleasant flavor of coffee is due to coffeon. None of the toxic 

 effects which follow large doses of coffee could be attributed to this. Neither fig 

 coffee nor chicory produced any effect. 



Do the volatile aromatic constituents of tea (tea oil) produce a noticeable 

 effect on man? K. B. Lehmann and B. Texdlau (Arch. Hyg.. 23 (1898), No. 4, pp.

 tract of tea obtained by distillation with steam and the material obtained by extrac- 

 tion with water or by extracting the dry tea with etber. In the authors' opinion the 

 flavor of tea is due to the oil, i. e., volatile material, but it has scarcely any other 

 effect.
