These findings, then reveal an animal dyinn- of an infec- 

 tion with its phagocytic mechanism, so far at least as experi- 

 mental standards can determine, functioning with an efficiency 

 considerably above the normal ar;ainst the specific or.^anism^ and 

 without any demonstrable decrease in opsonic activity against 

 the oiher bacteria used in the test. 



Experiment 9. — This experiment v/as intended as a dupli- 

 cate of the preceeding experiment. The conditions of the test, 

 paralleling as nearly as possible those of No. 8, are given in 

 the accompanying table. Although this infection resulted in 

 death it ran a much m.ilddr course than the typhoid infection 

 recorded above. There was only slight emaciation at death, and 

 there was a complete absence of macroscopic lesions.
