swollen four days liefore deatli, and the pneumonia whic h 

 had been present had become more marked. The autopsy 

 showed broncho-pneumonia; and lesions of the kidneys 

 and other organs. The cultures from the lung-s showed 

 numerous streptococci, as well as Loeffler bacilli. The 

 cultures from the blood of the viiriousorg-ans showed pure 

 g-rowths of streptococci. Cultures from the blood of the 

 various org"ans showed pure g-rowths of streptococci. 

 When these streptococci were injected into a rabbit, they 

 were found to be of moderate virulence. His experience 

 had been that after the streptococci were passed through 

 a few rabbits they increased somewhat in virulence but 

 then the virulence remained stationary. 



The second case was that of a child of one year, with 

 laryngeal diphtheria and hig-h temperature. It was given 

 antitoxin. Twenty-four hours later it was intubated, but 

 after three and one half hours the tube was removed. 

 Thirty-six hours after admission the temperature was 106 

 degrees F., and remained high until death. The child 

 remained the larg-er part of the time in a position of opis- 

 thotonos. The lung showed a late stage of broncho-pneu- 

 monia. Cultures from the lungs and other organs gave 

 streptococci. 



The third child had been sick only two days, but the 

 chest was full of rales. There was no membrane in the 

 throat; some diphtheria bacilli were found in the throat. 

 The temperature at the end of forty-eig-ht hours reached 

 107 degrees F., and the child died. The autopsy showed 

 both lung-s consolidated. ■ Cultures from the lungs and 

 from the blood showed the pneumococcus, and a few col- 

 onies of diphtheria bacilli were found in the cultures from 

 the lungs. 



Cultures from the blood of those dying early in diph- 

 theria, without high temperature, were usually sterile; 

 when there was a high temperature, sepitczemia was gen- 

 erally found. When the lung-s showed lesions, diphtheria 

 bacilli were always present in the consolidated areas. 

 Streptococci were also found. The diphtheria bacilli were 

 found in fourteen cases. It had been suggested by Dr. H.
