cussed show a parallelism in their curves of lipolytic activity, as measured by 

 the liberation of acid from ethyl butyrate and their curves of proteolysis. This 

 parallelism is discernible in cultures in plain, dextrose, mannit, and glycerin 

 broths." 



The antigenic properties of glycoproteins, C. H. Elliott {Jour. Infect. 

 Diseases, 15 {19U), No. 3, pp. 501-517).— The results of anaphylaxis, precipita- 

 tion and complement fixation tests of glycoproteins (ox tendon mucin, ox sub- 

 maxillary mucin, and swine stomach mucin) show that the glycoproteins are 

 capable of acting as antigens but are not so powerful as simple proteins. This 

 is in accordance with the findings of other investigators with other compound 

 pi-oteins, as well as with simple proteins modified by the addition of various 

 substances. 



" Eacli mucin gives rise to an antiserum that reacts with itself in compara- 

 tively high dilutions; with the blood serum of the same species to a less de- 

 gree ; and with the other mucins almost as well as with the blood serum. The 

 reaction with the other mucins is independent of species and the antiserum does 

 not react with the blood serum of the different species. 



" The present study does not throw any light on the nature of the union of 

 the protein and carbohydrate components of the glycoproteins, excepting that 

 it demonstrates that the antigenic properties of this class of compound proteins 

 are different from the antigenic properties of another common class of com- 

 pound proteins, the ' nucleoproteins ' which as such are said to produce specific 

 antibodies for themselves. While the antibodies produced by the mucins do 

 react with the blood serum of the same species, still there are very marked 

 quantitative differences in favor of the homologous mucin. In so far as the 

 antibodies produced by one mucin react with other mucins from a different 

 species as well as from the same species, support is given to the theory that 

 specificity depends on the chemical nature of the antigenic protein rather than 

 its biological origin." 



Some new distomes from the intestinal tract of domestic animals and of 

 pelicans for which fish serve as the source of infection, .J. Ciurea {Ztschr. 

 Infektionskrank. u. Hyg. Haustiere, 16 {1915), No. 6, pp. 445-458, pi. 1, figs. 

 S). — Three species of the new genus Loossia are described as new to science, 

 namely, L. rommiica from the dog, L. parca from the cat, and L. dobrogiensis 

 from the pelican {Pelecanus onocrotalus) . Feeding experiments show L. ro- 

 manica to occur in Esox lucitis and different fresh water fish of the subfamily 

 Cyprininre, with the exception of Tinea tinea, and L. parva was once found in a 

 cat after it had been fed on E. Iiicius. 



The discovery of the anthrax bacillus, O. Malm {Ztschr. Infektionskrank. 

 n. Hyg. Haustiere, 15 {1914), No. 3-4, pp. 195-208) .—This is a historical 

 review. 



Remarks on the work of W. Pfeiler and G. Weber on the action of mallein 

 on sound horses and the significance of the conglutination reaction for the 

 diagnosis of glanders, J. ScHNtJEEK {Ztschr. Infektionskrank. u. Hyg. 

 Haustiere, 16 {1915), No. 4, pp. 305-308). — It is stated that the conditions under 

 which Pfeiler and Weber conducted the experiments (E. S. R., 33, p. 479) are 

 not those which obtain in practice, consequently the data can not be directly 

 applied to practical conditions. 



A reply to the remarks of Prof, J, Schniirer on the work of W. Pfeiler 

 and G, Weber about the action of mallein with sound horses and the sig- 

 nificance of the conglutination reaction for the diagnosis of glanders, W, 

 Pfeiler {Ztschr. Infektionskrank. u. Hyg. Haustiere, 16 {1915), No. 5, pp. 383, 

 384). — A discussion of the objects of tlie work previously reported (E. S, R,, 

 33, p, 479).
