that the Cigar Manufacturers Association of 

 Hamburg reported that in the cholera epidemic 

 of 1892 in that city, only 8 out of 5,000 em- 

 ployes in the cigar factories there were at- 

 tacked by the disease and that there were only 

 4 deaths. Professor Wenck, of the Imperial 

 Institute of Berlin, has published an account of 

 this cholera epidemic (see Laucett francaise, 

 Paris, 1912, p. 1425). His conclusions favor 

 the preservative action of tobacco. It was 

 clearly shown that slightly moist tobacco was a 

 fatal germicide for the cholera bacillus; all 

 microbes die in it in 24 hours. The examination 

 of cigars made in Hamburg during the epidemic 

 showed that they were absolutely free from 

 bacilli. Wenck asserts also that cholera mic- 

 robes die in % hour, 1 hour, and 2 hours after 

 having been placed in contact with the smoke 

 of Brazilian, Sumatran and Havana tobacco. 

 The fumes of tobacco will besides kill in five 

 minutes the cholera microbes obtained from 

 saliva. Fullerton already quoted examined a 

 small number of mouths (74) in the Johns 

 Hopkins Hospital at Baltimore. Of those who 

 did not use tobacco in any form a larger per- 

 centage showed signs of dental caries and decay 

 of an advanced stage than in the case of tobacco 

 users. Similarly in the case of women who 

 never used tobacco ; and, although there was a
