Series 17. — Inoculations with the strain "Maassen Alt" in monkeys. 



November 3 : Six 48-hour agar slant cultures of "Maassen Alt" were sus- 

 pended in 7 cubic centimeters of bouillon. Animals numbered 1309 to 1371 

 were each inoculated subcutaneously with 2 cubic centimeters of this sus- 

 pension which equals nearly 2 agar slants, and animal number 1372 with 1 cubic 

 centimeter, or nearly 1 agar slant of "Maassen Alt." On November 23, twenty 

 days after the vaccination, 2 agar slant cultures of "Pest Virulent" (from guinea 

 pig number 1452, second transplant) were suspended in 10 cubic centimeters of 

 bouillon and each animal was reinoculated subcutaneously, on the opposite side 

 of the body to that upon which previous inoculation had been performed, with 

 0.25 cubic centimeter of this suspension, which is equal to i oese "Pest Virulent." 

 Eleven control animals were at the same time also inoculated subcutaneously 

 with the same dose.
