Figure 2. Photomicrograph of the plant Bacillus tuberculosis, 

 an organism that keeps its individuality under ordinary growing 

 conditions for about thirty minutes. Owing to the habit of this 

 organism of living as a parasite within the body of man, the 

 average annual number of deaths in the entire state of New York 

 is 15,805; in the United States annually 101,417; and an esti- 

 mated number of between two and two and a half million 

 deaths annually in the entire world. Photograph by Henry N.

 of vital statistics for New York State.
