The Diagnosis of Enteric Fever {Tijyhoid and Paratyphoid A and B) by 

 Agglutination Tests. W. C. Davison. (Jour. A. M. A., 1916, 66, 1297.) 

 Macroscopic agglutination tests made in accordance with the quan- 

 titative technic of Dreyer are reliable as diagnostic procedures. 



In cases of suspected typhoid in persons who have received prophy- 

 lactic inoculation a series of tests niade at intervals of 5 to 10 days are 

 necessary to establish the diagnosis. — G. H. S. 



Notes on the Etiology of the Recent Epidemic of Pseudo-Influenza. W. 

 W. Williams and W. Burdick. (Medical Record, 1916, 89, 876- 



877 ) 



A streptococcus was isolated from cases of pseudo-influenza, which, 

 immediately after isolation, was virulent for mice and rabbits. Au- 

 topsy of rabbits, killed forty-eight hours after inoculation with the 

 strain, revealed a tracheal and bronchial inflammation, suggestive of 

 a selective action. After four or five generations of subculture, how- 

 ever, no such selective action was manifest. Upon artificial cultiva- 

 tion' the organism also reverted to the usual cultural characteristics.

Bacteriology in Conjunction with Homeopathic Prescribing. W. W. 

 Irving. (Jour, of Oph., Otol. and Laryng., 1916, 22, 490.) 

 The author understands the action of the homoepathic remedy to be 

 much the same as that of vaccines, in stimulating the body tissues to 

 greater resistance. " Or does the remedy stimulate the anti body func- 

 tion or does it act as a germicide?" 



By a study based on the above theories he expects to produce a ma- 

 teria medica which will unify the organism with the remedy.— C. P .B. 



Anopheles Punctipennis, a Host of Tertian Malaria W.J. King. 

 (Am Jour. Trop. Dis. and Prevent. Med., 1916, 8, 426-432.) 

 In two comparative experiments Anopheles punctipennis was proven 

 to be an efficient host for the Plasmodium vivax. These mosquitoes 

 were bred from the larvae and pupae collected in the open. 1 hey were 

 fed individually on a gametocyte carrier. A high percentage of infec- 

 tion was obtained. Controls of A. quadrimaculatus were also found 

 to be infected. The infection in all instances was followed to the sali- 

 vary glands. — F. M. J. 



Simultaneous Injections of Streptococci and Dahlia in the Guinea-pig. 

 W H. Hoffman, W. B. Ma^clurb, and L. W. Sauer. (Jour. Infect. 

 Diseases, 1916, 18, 353-357.) ...... ,. ,. r ^^ 



From a study of the effects of combined injections the authors found 

 that an injurious reaction resulted, although no change was detected 

 in the opsonic content of the serum or in the hemolytic reactions in 

 which the serum was employed. They conclude that ' intravenous in- 

 jection is not warranted as a therapeutic measure. —P. B. M.
