causing more or less disease. Public attention must first be called 

 to the facility with which such water is infected and its dangers ; 

 but eventually we can expect boards of health, composed at least 

 in part of men trained in bacteriology, and whose business it 

 shall be, by its aid, to limit the spread of disease and so add to 

 the sum of human existence.

September /, j8g2. — The regular monthly meeting was held 

 at the residence of Dr. H. M. Whelpley, there being an unusually 

 large attendance. 



Mr. Harry Stark reported briefly some experiments he is 

 making in devising a serviceable and cheap camera for micro- 

 photography. He promised to explain the device more fully and 

 present a finished instrument at the October meeting. 



Dr. H. M. Whelpley exhibited and illustrated the use of many 

 of his large variety of microscope accessories, all of which was 

 of absorbing interest to the members. 



E. E. Schlueter made application for membership. 



The treasurer, Dr. Whelpley, reported on the condition of the 

 treasury, which showed that the club's finances are in exception-

After adjournment Dr. and Mrs. Whelpley held an informal 

 reception in the parlors, of their handsome new residence. The

 every meeting of the club could be held under such pleasant con- 

 ditions.

 and complete. He used a slight ring of Brown's rubber cement 

 to support the cover-glass. Dr. Bessey exhibited vast fibres from

 with potash in a very short time and better results can be had

 exercises was discussed and a new plan reported, which will be 

 passed upon at the next meeting.
