158 THE MICROSCOPE. Oct. • 



investigations of the effects of tobacco during- the epi- 

 demic of cholei'a at Hamburg states that there were no 

 live microbes after twenty-four hours in the cigars made 

 up with water containing 1,500,000 cholera microbes to the 

 cubic centimeter. There were no traces of microbes to 

 be found in any of the cigars manufactured at Hamburg 

 during the course of the epidemic. The microbes die in 

 half to two hour's exposure to tobacco smoke, Brazil, Su- 

 matra or Havana tobacco. The smoke of any cigar kills 

 the microbes. The smoke kills in five minutes all the mi- 

 crobes in the saliva. Another fact established is that none 

 of the persons employed in the tobacco factories at Ham- 

 burg, contracted cholera. — Gaz. degli Osp. e delle Clin. 



Typhoid Fever Caused by Ice Cream. — According to the 

 Boston Medical and Surg-ical Journal, August 27, a con- 

 siderable, but not widely extended, outbreak of typhoid 

 fever occurred during the latter part of July in the town 

 of East Barrington, N. H. The cases were all traced to a 

 single source. The first case was an unrecognized one, 

 the patient being unwell but helping about the house and 

 doing part of the milking. It is supposed that he must 

 have in some way contaminated the milk, as by going to 

 stool and not washing his hands before returning to his 

 milking. The water supply was carefully examined and 

 found to be all right. On Friday evening a party was 

 given at the house and the guests were given ice cream 

 made at home from the milk supply above referred to. 

 Within the next ten or fourteen days fourteen of the 

 guests came down with typhoid fever — eight in the town 

 of Barrington, of whom one died ; two in Lee ; one each in 

 Dover, Rochester and Woodbury, N. H., and one in Haver- 

 hill, Mass. All of these out-of-town cases were guests at 

 the party. No other cases occurred in the town, and all 

 were partakers of the cream.
