Washingtou, and Oregon become acquainted with tlie plant and take proper 

 precautions to prevent the sheep from eating any large quantity of it. 



Mold fungi in oil cake, E. Schneider (Milchw. Zentbl., 42 (1913), No. 10, 

 p. 313). — The author finds that draft oxen and young cows which have calved 

 for the first time are not affected by moldy oil cake. 



The immunological relationship of hordein of barley and gliadin of wheat 

 as shown by the complement fixation, passive anaphylaxis, and precipitin 

 reactions. — The biological reactions of the vegetable proteins, IV, G. C. 

 Lake, T. B. Osborne and H. G. Wells {Jour. Infect. Diseases, 14 {1914), No. 2, 

 pp. 364-316). — Among the principal conclusions drawn from these experiments, 

 which continue earlier work (E. S. R., 30, p. 778), were the following: 



"Carefully purified preparations of vegetable proteins readily produce anti- 

 sei-a. The antisera obtained in our experiments differed in their range of reac- 

 t'ou^', some giving only the complement fixation, some the complement fixation 

 and precipitin tests, while others in addition conferred passive anaphylaxis 

 to guinea pigs. 



"Antisera to the same protein obtained from different individual animals differ 

 in their reactions, for some unknown cause. ... A specific complement fixation 

 reaction in high dilution does not necessarily accompany reactions with the 

 heterologous proteins, nor can such .serum always produce the passive anaphy- 

 laxis reaction. Both the precipitin and passive anaphylaxis reactions appear 

 later in immunization than the complement fixation reaction, and seem to be 

 closely related to each other in delicacy." 



The anaphylactogenic activity of some vegetable proteins. — The biological 

 reactions of the vegetable proteins, V, H. G. Wells and T. B. Osbokne {Jour. 

 Infect. Diseases, 14 (1914), No. 2, pp. S77-58.4)-— According to the authors' 

 conclusions the data i)resented supi)ort the assumption " that the severity of 

 the anaphylaxis reactions produced by intraperitoneal injections of dilute, 

 alkalin solutions of vegetable proteins is. approximately, in inverse ratio to their 

 relative precipitability when their solutions are mixed with the peritoneal fluid. 



" Proteins like edestin. which are readily precipitated and only slowly redis- 

 solved under conditions similar to those presumably prevailing in the peritoneum, 

 rarely produce a fatal intoxication ; whereas those that are less easily precipi- 

 tated and more readily dissolved give fatal reactions in much smaller doses." 



Other conclusions have to do with lethal and minimum intoxicating doses. 



About the specificity and other properties of the ectoproteases, C. Febmi

 This deals with the distribution of proteolytic enzyms in the animal and vege- 

 table kingdoms. For this purpose organs of animals belonging to the Mammalia, 

 Aves, Reptilia, Amphibia, Pisces, Mollusca, Insecta, Arachnida, Myriapoda, 

 Crustacea, Echinodermata, Vermes, Spongilla, Coelenterata, and Protozoa were 

 used. The proteolytic enzyms in the plant kingdom were from pathogenic and 

 nonpathogenic bacteria, molds, and imperfect fungi, and the studies were made 

 with autolyzed press juices from animal organs. 



In this connection, the time at which the proteolytic enzyms selected for dif- 

 ferent substrata appear during the development of the animal or plant in ques- 

 tion is considered. In addition the results of experiments made on the activa- 

 tion of certain proenzyms, exposing the enzyms (vegetable and animal) to light 

 and heat, filtration through porcelain filters, and dialyzing tests, are recorded. 



A preliminary report on the value of leucocytic extract from a therapeutic 

 standpoint, R. A. Abchibald {Proc. Anicr. Vet. Med. Assoc, 50 {1913), pp. 451-
