 Dr. Louis Heitzmann, of New York, being introduced by the 



Vice-President, read the paper announced on the programme, en- 

 titled " The Cause of Asiatic Cholera." This paper is published 

 in this number of the Journal, page 7. 



Dr. George M. Sternberg, of Brooklyn, being introduced by 

 the Vice-President, gave many interesting and valuable points of 

 information on the action and prevention of cholera. He stated, 

 with other items, that the spirillum is quickly killed by desicca- 

 tion. If little squares of infected blanket are exposed to sunlight 

 two, three, and four hours, it is found that the spirillum will grow 

 after two hours' exposure, but not after four hours' exposure. 

 Sunlight is one of the best disinfectants. In the late operations 

 of the quarantine of our port many articles of clean linen were 

 injured by the steam process, when a little sunlight would have 

 been equally effective. In future operations, doubtless, sunlight 

 would be much employed. With ordinary care nurses of cholera 

 patients do not contract the disease. There is no great danger 

 from germs wafted over in the air from an infected region. 



A discussion of the subject also ensued, participated in by Dr. 

 Carl Heitzmann, Dr. Louis Heitzmann, Dr. L. Schoney, Rev. 

 George E. F. Haas, and others. 



On motion the thanks of the Society were tendered Dr. Louis 

 Heitzmann and Dr. George M. Sternberg for their interesting 

 addresses.
