158 Action on Staphylococcus pyogenes by Hin.wm Blood, etc. 



inoculation was followed in a ty-pical manner by a negative and positive 

 phase. With respect to this last it will be seen that the curve 

 attained its acme on the fifth day, and then declined in the usual 



manner. 



Within a week after the second inoculation practically every trace of 

 sycosis had disappeared. The patient was now lost sight of. 



Curve 3. The curve here in question applies to a labourer who 



was the subject of aggravated sycosis. He had suffered at intervals 

 from childhood from boils and other chronic staphylococcus infections. 

 A pure cultivation of Staphylococcus aureus was obtained from the 

 inflamed hair follicles. He had been treated ineffectually for months 

 by the usual methods. 



As will be seen on reference to the chart, the phagocytic power 

 of the blood was here investigated only from week to week instead of 

 at more frequent intervals. As a result the positive phase of the 

 reaction is alone on record in the case of the first three inoculations. 

 In the case of the fourth inoculation conducted with a larger 

 quantum of the vaccine the negative phase was still in evidence 

 6 days after the inoculation. 



The patient, who was all but completely cured at the date upon 

 which the curve concludes, afterwards relapsed after free indulgence 

 in alcohol. He is now, as a result of further inoculations, again 

 practically well. 



Curve 4. This curve applies to a healthy man of 24 who, while in 

 training for a boat race, developed a boil on his gluteal region and 

 subsequently a crop of boils on his neck. 



CURVE 4. 



Reference to the curve will show that his phagocytic index stood at 

 the date of his first inoculation at 0'S4.
