* Monkey number 1285 was inoculated October 20 by thrusting beneath the skin a 5 cubic centim- 

 eter syringe needle which had been dipped in a bouillon suspension of an agar slant of "Pest Viru- 

 lent." It suffered a mild pest infection and on October 25 was reinoculated with 2 oesen of the 

 strain "Pest Virulent." It survived this inoculation and on November 16 was killed by bleeding 

 and the value of its serum tested as above. Its agglutinative power tested November 17 was found 

 to be entirely negative even in dilutions of 1 or 2. 



t Monkey number 1278 was vaccinated October 19 with a culture of "Pest Avirulent." On October 

 30 it was reinoculated with 2 oesen "Pest Virulent," and proved to be immune. It was killed 

 November 16 by bleeding and the anti-infectious value of its serum tested as above. Its aggluti- 

 native power tested November 17 was entirely negative in dilutions as low as 1 to 2 or 1 to 4 after 

 four hours. 



I Monkey number 1231 was inoculated on October 20 by thrusting beneath the skin a 5 cubic centi- 

 meter syringe needle that had previously been dipped in a suspension of an agar slant of "Pest 

 Virulent." It suffered a mild pest infection and on October 25 was inoculated with 2 oesen of "Pest 

 Virulent" which it survived. On November 16 it was killed by bleeding and the anti-infectious 

 power of its serum tested as above. Its agglutinative value with the strain "Pest Virulent" was 

 tested on November 17 and found to be entirely negative in dilutions of 1 to 2 and 1 to' 4 after four 

 hours.
