When he realized that he had tuberculosis, he went to end his 

 days in the Adirondack Mountains which he loved. Strangely 

 enough, his health be- 

 gan to improve. Two 

 or three doctors, hear- 

 ing of his improvement, 

 sent other tubercular 

 patients to him and a 

 small sanitarium was 

 thus started in the 

 northern part of New 

 York State. Trudeau 

 heard of Koch's work 

 and went back to New 

 York city to learn the 

 laboratory methods of 

 isolating the tubercle 

 germs. Then, return- 

 ing to the mountains, 

 he started experiment- 

 ing on rabbits. He 

 took three sets of rab- 

 bits. He inoculated two 

 of them with tubercle 

 bacilli. One of these 

 sets he placed in a dark 

 camp box that was 

 poorly ventilated, and 

 gave them an insuffi-

 light, and food. The third set, that had not been inoculated, 

 was also put in very unfavorable surroundings. The results were

If the trends between 1900 and 1922 are averaged, the 

 expectation of the tuberculosis death rate for 1937 is about 

 40 per 100,000. If the decrease of 1926 and 1927 con- 

 tinues, the death rate in 1937 would be 20 per 100,000. 

 A greater decrease than has yet been shown is necessary 

 to bring the death rate to 0. (From Health and Wealth by
