President Pritchett in the chair, and 15 members pres- 
ent. The President introduced Dr. Armand N. Ravold, who 
then presented a paper ‘*On the Typhoid Bacillus found in 
the Mississippi River Water.’’ Dr. Ravold prefaced his paper 
with a brief lecture. He described the modern microscope, 
and the present classification of micro-organisms and bacteria. 
The lecturer then described the method of incubating, plating 
out and separating pure cultures of bacteria. In the very 
excellent and interesting paper which followed, Dr. Ravold 
related his experience, in the finding in the Mississippi water 
of a certain bacillus, which he called Number 21, and which 
after long and careful work he has succeeded in almost con- 
clusively identifying as the well-known Bacillus Typhesis. 
The lecture concluded with some excellent stereopticon views 
of micro-photographs made by Dr. Ravold. A discussion 
followed, the lecturer called attention to the great need in St. 
Louis of an isolation hospital where malignant diseases due to 
pathogenic germs could be treated. 
Prof. Nipher moved that a committee be appointed by the 
President to investigate the matter of the meteorological work 
heretofore carried on in Forest Park, and see if it could not 
be carried on under the direction of the Academy.
