Observations in regard to the feeding" value and other properties of some 

 plants in the Government of Viatka, M. Papkow {Trudy lifiiro Prlld. Hot. 

 {Bui. Angeiv. Bot.). 4 {1911), No. 11, pp. 552-562).— A statement in regard to 

 the value of certain plants as a feed for animals, especially from the stand- 

 point of toxicity. 



Analyses of some Wyoming- larkspurs, I, F. W. ITeyl, F. E. Hepner, and 

 S. K. LoY {Jour. Amer. Chcm. Soc, 35 {1913). No. 7, pp. 880-885).— In this 

 paper are given the results of proximate analyses of the leaves, pods, and roots 

 of Delphinium f/cifcri, D. glaucum, and D. nelyonii. The roots of the latter 

 have previously been found to contain a crystallizable alkaloid melting at 1S4 

 to 185° C. and to which the fornuila C23II33NO7 had bet^i assigned. 



As the result of an examination of the leaves, which have been subjected to 

 a most complete proximate analysis, it would seem that the leaves of D. gcyeri 

 are the most toxic of the 3 species because of their high crude alkaloid content. 

 This alkaloid will, however, be studied further in order to note whether the 

 alkaloids from the different larkspurs behave alike pharmacodynamically. 

 " In order to gain some idea as to the toxicity of the crude alkaloidal mixture 

 obtained from the leaves of D. geyeri, an intraperitoneal injection of 0.0.otj4 gm. 

 of the alkaloid as sulphate was made upon a guinea pig weighing 675 gm. 

 Death followed in 9 minutes. In another ex]")eriment an intraperitoneal injec- 

 tion of 0.02 gm. as sulphate killed a guinea ]jig weighing 623 gm. in 35 minutes." 



As D. geyeri is the most abundant species in Wyoming, it will be subjected 

 to a complete chemical examination of all its constituents. 



An analysis of the ash of the leaves of D. geyeri is included. 



Poisoning of two cattle by tobacco juice, G. Giovanoli {Sclnvei.:;. Arch. 

 Tierheilk., 55 {1913), Xo. //, pp. 178-182; ahs. in Yet. Rec., 26 {1913), Ko. 1328, 

 p. 887). — The author reports observations in which cattle washed with a 

 solution of tobacco juice to destroy lice were affected and the death of two 

 heifers resulted. 



Concerning sarcosporidin, L. Cominotti {Centhl. Bald, [efc], 1. Aht., Orig., 

 69 {1913), Xo. 4, pp. 26 Jf-271).— The author finds that the sheep sarcosporid 

 {Sarcocyslis teneUu) contains a substance (sarcosporidin) which exerts a toxic 

 action upon rabbits and sparrows characterized by paralytic symptons. The 

 mininumi lethal dose of the di*y substance for the rabbit is 0.0001 gm. It 13 

 possible in guinea pigs that are resistant to the toxic action of the sarcospori- 

 din to produce anaphylactic shock through repeated injections, as well as to 

 immunize actively rabbits through the injection of increased doses of the 

 sarcosporid dry substance. An immune serum may be obtained from the goat 

 through the administration of a series of intravenous injections of the diy 

 sub.stance, but the action of this immune serum is of short duration.
