The distribution in wheat, rice, and maize grains of the substance, the 

 deficiency of which in a diet causes polyneuritis in birds and beriberi in 

 man, Haebiette Chick and E. Maegaeet Hume {Proc. Roy. Soc. [London], 

 Ser. B, 90 {1917), No. B 62It, pp. 44-60).— This is a report of experiments which 

 deal with the distribution of " antineuritic " vitamins in the various constituents 

 of wheat, maize, and rye grains. 



" Wheat endosperm, after removal of the aleurone layer in the ordinary 

 milling processes, constitutes white flour. It is deficient in this vitamin, and 

 if used as an exclusive diet will induce polyneuritis in pigeons (or beriberi in 

 man) in a manner identical with polished rice. In both the rice and wheat grain 

 the antineuritic vitamin is concentrated mainly in the germ or embryo ; it is 

 also present to a less degree in the bran (pericarp and aleurone layer), probably 

 in the aleurone layer. 



" In the case of maize grain the embryo also possesses marked antineuritic 

 properties. Here the scutellum can be separated from the ' plantlet ' and 

 separately investigated. Both these constituents of the embryo were found to 

 contain antineuritic vitamin." 



Researches on the diagnosis of pregnancy in cows, mares, and goats by 

 the Abderhalden method, R. Giuliani {Clin. Vet. [Milan'], Rass. Pol. Sanit. e 

 Tg., 40 {1917), No. 17-18. pp. 494-428).— Previous literature on the subject of 

 the pregnancy test as applied to domestic animals is reviewed, and investiga- 

 tions reported on the value of the test, particularly in connection with artificial 

 fertilization as described by Pirocchi (E. S. R., 33, p. 71). The dialyzation 

 method was carefully followed according to the Abderhalden technique. From 

 the results of the experiments recorded the author draws the following con- 

 clusions : 



(1) The methods can be relied upon in the majority of cases provided that 

 the technique of Aberhalden (E. S. R., 32, p. 270) be followed scrupulously, 

 that control tests be made with serum alone and with inactive serum and
