A manual of bacteriology, R. T. Hewlett (London: J. & A. Churchill, 1918, 

 6. ed., pp. X+169, pis. SI, figs. 69). — In the present edition of this manual of 

 bacteriology, an earlier edition of which has been previously noted (E. S. R., 

 14, p. 491), the text has been revised throughout and much new material has 

 been introduced, including considerable additions to the sections dealing with 

 anaphylaxis, agglutination, and immunity. The chapter dealing with anaerobic 

 organisms has been enlargetl to include an account of the relation of this 

 group of organisms to war injuries. 



Heterolysins, II, A. Sordetxi and G. Fischer {Rev. Inst. Bact. [Argentinal, 

 2 {1919), No. 2, pp. 201-210). — Continuing the investigation previously noted 

 (E. S. R., 40, p. 578), the authors have found heterolysins in the organs of the 

 wild and domesticated guinea pigs and in guinea pig and chicken sarcomata. 

 Rat sarcomata and carcinomata did not contain heterolysins. 



The influence of desiccation on certain normal immune bodies, H. T. Kaes- 

 NERand K. R. Collins (Jotir. Infect. Diseases, 25 {1919), No. 5, pp. 427-/(32). — ^A 

 comparative study is reported of the effects on the normal antibodies in the 

 l»lood of horses and goats of drying in the air, or in vacuo over sulphuric acid at 

 room temperature, and freezing and drying over sulphuric acid in vacuo. The 

 results obtained are summarized as follows : 



"The normal antibodies in the serum of the horse and goat are gradually 

 decreased by drying. The agglutinins and hemagglutinins are less affected by 

 drying if the serum is frozen while desiccation is going on. The loss of titer 

 in the nondialyzed serum takes place within the first ten days, while it is de- 

 layed in the dialyzed serum until after the twentieth day. The decrease of 

 agglutinins in the dialyzed serum is uniform for all methods of drying until 

 after two months, while in the nondialyzed serum the loss is greater in the 

 serum that was not frozen and still greater in the serum dried in the air. 

 The pH of dried serum is slightly greater tlian in the original serum, and as 

 ihe loss of agglutinins becomes greater the difference is more marked. Dried 

 serum dissolved and dx'ied again shows definite changes in the formation of 

 <rystals." 



Notes concerning the concentration of antitoxic sera, A. Soruelli {Rev. 

 Jnst. Bact. [Anjentinal, 2 {1919), No. 2, pp. 211-2H).—The author reports ex- 

 cellent results obtained in the concentration of antitoxic sera by the Homer 

 method previously noted (E. S. R., 40, p. 287). Concentrations of the plasma
