ABSTRACTS 685 



Particular emphasis is laid upon the necessity for preventive meas- 

 ures, especially the eradication of polhnating weeds. — M. W. C. 



The Coexistence of Antibody and Antigen in the Body. B. S. Denzer. 



Jour. Infect. Diseases, 1916, 18, 631-645. 



Antigen and antibody persisted in both the cells and blood for three 

 weeks after immunization of a guinea-pig with foreign serum. Anti- 

 gen was demonstrable in the cells and in the blood for 17 days. Later 

 it disappeared. Antibody was demonstrable in the cells from the 

 ninth day and in the blood after the fourteenth day. — P. B. H. 



The Action of Antiseptics in Pasteur Antirahic Emulsions. Daniel W. 



Poor. Collected Studies, Bureau of Laboratories, New York City, 



1914-1915, 8, 191. 



In an effort to obtain a substitute for glycerin in antirabic emul- 

 sions, several antiseptics were tried. 



Chinosol in dilutions of 1:10,000; 1:15,000 and 1:20,000 offered 

 no advantages over other agents, which are non-proprietary and more 

 easily obtainable. Dilutions of 1 : 10,000 effected the strength of the 

 rabies virus, and 1 : 30,000 did not hold in check extraneous organisms. 

 Camphor and menthol were of little value. Carbolic acid (0.2 per 

 cent) gave the best result, the rabicidal effect being less than that of 

 20 per cent glycerin, and the antiseptic effect as good. — T. G. H. 



An Epidemic of Whooping Cough Treated with Pertussis Stock Vaccine. 



Matthias Nicoll, Jr., and Paul Luttinger. Collected Studies, 



Bureau of Laboratories, New York City, 1914-1915, 8, 86. 



Out of 350 children who had been exposed to whooping cough, half 

 were treated with pertussis vaccine. None of them took the disease. 

 If all had been treated, freedom from disease probably would have 

 been ascribed to the vaccine. 



The possibility of immunization against pertussus is still an open 

 question. — T. G. H. 



A Case of Sensitization to Witte's Peptone. K. R. Collins. Proc. 



N. Y. Pathol. Soc, 1916, 16, 46. 



The patient was a laboratory worker who acquired a very marked 

 sensitiveness to peptone, such that severe coryza, conjunctivitis and 

 edema of the glottis would follow inhalation of minute quantities of it. 

 He appeared not to be sensitized to other substances. — W. J. M. 



Preliminary Studies of the Antigenic Properties of Different Strains of 

 Bacillus Typhosus. Sanford B. Hooker. Proc. Soc. Exp. Biol, 

 and Med., 1916, 13, 139. 



Serum cross-titrations with standardized antigens indicated a divi- 

 sion of typhoid strains into three groups. Group I strains cross- 

 fixed with all antigens. Those of Group II cross-fixed with each other
