Inoculation against Tijphoid in Maryland. F. W. Hachtel and H. 



W. Stoner. Amer. Jour. Pub. Health, 1916, 6, 703-706. 



Of 14,795 residents of Maryland inoculated for from one to five years 

 with typhoid vaccine but ten have since had the disease, which gives 

 an attack rate of 6.75 per 10,000 persons. In contrast the attack rate 

 for the state for a sunilar period (5 years) was 33.30 per 10,000 persons.

Autolysis of Anaphylactic and Immune Tissues. W. H. Manwaring 

 AND Ruth Oppenheimer. Proc. Soc. Exp. Biol, and Med., 1916, 

 13, 176. 

 The post-mortem autolysis of livers from normal, anaphylactic and 



immune guinea pigs was tested by determination of coagulable and 



non-coagulable nitrogen. Autolysis was increased in the immune 



livers.— W. J. M. 



Universal Immunisation. H. B. Baruch. Medical Record, 1916, 90 > 



372-373. 



The author proposes that children should be injected at an early 

 age with serum of adults who have recovered from scarlet fever, 

 measles, and other infectious diseases. The author maintains that such 

 serum contains antibodies and should therefore confer immunity upon 

 the recipient.— M. W. C. 



The Bacteriological Aspect of the Abderhalden Test. D. Rivas and A. 



C. Buckley. Jour. Med. Res., 1916, 34, 297-304. 



The article is essentially a summary of recent opinions regarding 

 the value of the Abderhalden reaction as a diagnostic test. On the 

 theory that the presence of products of tryptic digestion may be indi- 

 cated by the formation of indol by B. coli after a short incubation, 

 the authors apply this test to a series of cases with negative results.

The Effects of Exposure to Cold upon Experimental Infections of the Re- 

 spiratory Tract. J. A. Miller and W. C. Noble. Jour. Exp. 

 Med., 1916, 24, 223-232. 



By subjecting rabbits to sudden changes in temperature, from low 

 to high, and from high to low, and then inoculating them by spraying 

 cultures of Bacillus bovisepticus on the nasal mucous membrane, it was 

 found that any marked change of temperature predisposed the rab- 

 bits to this infection, the severity of which varies with the amount of 

 change, and that a change from low to high temperature has an even 

 more marked effect than that from high to low. — B. W.
