At the same time, on September 4, 1906, 10 c.c. of the same 

 culture as used in the previous experiment were administered to the 

 bull. The culture was diluted in two Erlenmeyer flasks of ordinary 

 tap-water (240 c.c), and given by means of the stomach-pump. 

 This method of administration was employed to obviate the risk of 

 the drench passing into the rumen. The lumen of the tube was 

 flushed out with a further quantity of water. The animal had been 

 previously tested with tuberculin, but did not respond. 



As the companion animal appeared ill on September 25, the 

 temperatui'e of this animal was also taken ; and I append the tempera- 

 tures for purposes of comparison.

The temperature fluctuated more than in perfect health ; but still, 

 save on September 25, it was never as high as any temperature 

 recorded in its companion. I determined to apply the tuberculin test 

 after the lapse of a short time. According to von Behring, the tuber- 

 culin test should not be applied until after three months had elapsed 

 from^ date of infection. Any test prior to that is said to be useless, 

 because infection has not been established. 



The test I applied fifty days after injection; and it shows that von 

 Eehring's statement is incorrect. The tuberculin was injected at 

 11.30 p.m. on October 24, the temperature at the time of inoculation 

 being 101-8.
