A Simplijied Method of Producing a Potent Precipitin Serum. Wallace 



V. Smith. (Jour. Med. Res., 1916, 34. 169-175.) 



The author finds that the serum proteins precipitated from blood 

 by means of one-third saturation with ammonium sulphate consti- 

 tute a potent antigen for the preparation of precipitin serum in rab- 

 bits. The dried precipitate can be kept on hand over a long period 

 without impairment. — H. W. L. 



The Agglutination Reaction with Sera Derived from Human Cases of 

 Leprosy and from the Experimental Animal upon Various Members of 

 the Acid-Fast Group. W. H. Harris and J. A. Lanford. (Jour. 

 Med. Res., 1916, 34, 157-167.) 



Sera from 20 human cases of leprosy tested against several strains 

 of B. leprae, human, bovine, and avian tubercle baciUi, and several of 

 the non-pathogenic acid-fasts, failed to show any regularity or speci- 

 ficity. The same was true of experimental sera produced by injections 

 of the various strains of leprosy bacilU into rabbits. — H. W. L. 



Observations on the Typhoid Reaction. C. R. Austrian and A. L. 

 Bloomfield. (Archives of Internal Medicine, 1916, 17, 663-669.) 

 By the typhoidin reaction individuals who had suffered from typhoid 

 fever or received prophylactic treatment could not be differentiated 

 from those who had never had the disease nor received vaccine treat- 

 ment. The reaction was positive in a large percentage of persons who 

 gave no history of typhoid fever or artificial immunization. — G. H. R. 



Erysipelas Migrans and Multiple Abscesses in a Six Months' Old Infant 

 Successfully Treat^'.d with Vaccines. L. Fischer. (Medical Record, 

 1916, 89, 734-735.) 



Report of a case, which showed no response to treatment with leuco- 

 descent light, ichthyol, evaporating lotions, or magnesium sulphate, but 

 in which decided improvement and finally complete recovery followed 

 the administration of stock streptococcus and autogenous vaccines. —

Vaccine Treatment. Ludvig Hektoen. (Jour, A, M. A., 1916, 66, 



1591-1594.) 



A discussion of the theory and practise of vaccine therapy. Follow- 

 ing accurate diagnostic procedure an autogenous vaccine would seem 

 the logical method of treatment. Stock vaccines and phylacogens, 

 which are not standardized and may not be specific, have a limited 

 application. — G. H. S. 



Is the Hyperleucocytosis Following the Injection of Typhoid Bacilli into 

 Immunized Rabbits Specific^ Helen I. McWilliams. (Journal of 

 Immunology, 1916, 1, 159.) 

 The experiments of Gay and Claypole showing hyperleucocytosis in 



immune rabbits following the injection of typhoid bacilli, were reviewed,
