 ence and Art, and it being deemed proper that some action

NEW disinfectant. 



Dr. L. A. Thompson presented a new disinfectant, which he 

 considered worthy the attention of the Association. 



new filter. 



Dr. Thompson proceeded to describe a new filter constructed 

 by him. He stated that water should be filtered not only for 

 drinking and cooking purposes, but for personal washing, and for 

 washing fine articles of clothing. Fine linen goods dipped into 

 unfiltered water are stained by the animal and vegetable sub- 

 stances suspended in the water. Dr. Thompson's filter is so con- 

 structed as to prevent the water as it passes through, from form- 

 ing gullies, and to cause it to percolate uniformly through the 

 whole mass of charcoal and quartz, which thus retains its effi- 

 ciency for a long period. He asked for the examination of this 

 filter, and of his disinfectant, by a committee, offering to send 

 the Association a filter and specimens of the disinfectant for 

 trial. 



The following committee was appointed, viz : Messrs. Stetson* 

 Seely and C. W. Smith.
