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 14 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
