 redness round the puncture had also vanished. 



On the sixth day, there was on the Aleutians, 

 round the pox, a raised red rim two lines broad, the 

 axillary glands were swelled in all of them. On this 

 day I again inoculated the Kamtschadale in two 

 places, the first being entirely healed up. In one 

 only of the Aleutians, the youngest, the lymph 

 was still quite fit for inoculation. But this time, 

 also, I foresaw that it was in vain, because the 

 lancet would not pass easily under the skin. The 

 event was, in fact, the same as the first time, so that 

 I dismissed him in three days. 



At the same time, I inoculated another Kamt- 

 schadale with the vaccine who had likewise been 

 twice inoculated in Kamtschatka without effect. 

 Three days after, the places vaccinated had risen 

 considerably, were red, and caused an itching; but 

 this was the highest point to which they advanced, 

 for, on the following day, all the symptoms had dis- 

 appeared, and did not return. He made me easy by
