cheese, and 1.7 per cent various fancy varieties. There has been a marked 

 decrease in the number of cream separators used by the factories, due to their 

 increased use on the farms. 



The scientific basis of cheese making" and the use of artificial rennet in 

 the manufacture of Emmental cheese, O. Allemann {Landiv. Jahrb. Schweiz, 

 27 {1913), No. 5, pp. 325-361; ahs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr. 

 Intel, and Plant Diseases, 4 {1913), No. 12, pp. 1920, 1921).— The author reports 

 as to the advisability of using artificial rennet in the making of Emmental 

 cheese. 



It was found that the natural rennet made by the cheese makers and the 

 rennet powder called artificial rennet do not differ much in their action. Aside 

 from the natural rennet being somewhat richer in lactic acid bacteria it is no- 

 wise superior to the artificial product.

Some immunity reactions of edestin. — III, The biological reactions of the 

 vegetable proteins, B. White and O. T. Avery {Jour. Infect. Diseases, 13 

 {1913), No. 1, pp. 103-123).— A continuation of work previously noted (E. S. R., 

 30, p. 680). 



" Crystallized preparations of edestin from hemp seed and gliadin from wheat 

 flour were used, and were specially prepared for anaphylactic experiments by 

 Dr. Thomas B. Osborne. They were dissolved in water with the addition of the 

 smallest possible amount of sodium hydrate necessary to effect solution. 



" Edestin, even in small amounts, agglutinates washed red blood corpuscles 

 of the sheep and of man. Both edestin-immune serum and peptone completely 

 inhibit this action under the conditions noted. Gliadin, in the amounts used, 

 exerts no agglutinating action. The serum of a rabbit which has been immu- 

 nized with edestin contains a precipitating antibody for edestin, but none for 

 gliadin ' in at least twice the concentration, giving a positive reaction with 

 edestin. Edestin, in the presence of edestin immune serum, when both are 

 used in nonanticomplementary and nonhemolytic amounts, completely binds 

 complement. Gliadin, in the presence of edestin immune serum, fails to bind 

 complement. 



" [As to the] sensitizing dose, 0.0000001 gm. edestin, injected intra peritoneally, 

 may be considered as the minimum sensitizing dose. Guinea pigs sensitized
