served that when the disease was in the 

 ascendant the greater the proportion of these 

 white corpuscles to be seen in the blood, 

 the more tenacious was the sputum, or peni- 

 cillium, and the weaker and worse in health 

 I felt; but when the disease was being 

 overcome, large quantities of the white 

 corpuscles came away so easily that they 

 seemed to have lost their cohesive power, and 

 their relative numbers lessened in the blood in 

 proportion." 



ONLY ONE IN FOUR HUNDRED IN PLACE OF ONE IN FORTY 

 LEUCOCYTES TO RED CORPUSCLES. 



" At present very few indeed are to be seen ; 

 only one in four hundred of the red in place of 

 ONE in FORTY, two or three years ago" [written 

 in 1869]. A note is added 



" A year or two after this, on examining the 

 blood, I found only one white corpuscle in five 

 thousand red corpuscles, when I never had 

 such exuberant health, mentally and physi- 

 cally."

IMPROVEMENT IN HEALTH AND INCREASE OF LEUCOCYTES 

 IN INVERSE RATIO. 



" The general health has improved in inverse 

 ratio to the number of white corpuscles seen 

 in the blood. The same results I have observed 

 in hundreds of others " (p. 127).
