[December 
October 20. Yesterday and today there has been but 
little discomfort. The lesions now have the appearance 
of small boils. They are a deep red in color, swollen and 
with some induration of the surrounding area. The indu- 
rated area surrounding No. 4 is about an inch and a half 
in extent. 
October 21. A severe stinging pain is occurring at inter- 
vals at Nos. 1 and 2 on my left arm. These two lesions 
are so close together that it is difficult to determine whether 
it is only one or both that cause the pain. There is also 
a severe itching at No. 5 and an occasional sharp, stabbing 
pain in No. 6. 
October 22. During the night I was awakened several 
times by sharp stinging pain in Nos. 1 and 2. There was 
intense itching in No. 3 and on two occasions when I awak- 
ened during the night I found that apparently I had been 
scratching this lesion while still asleep. This morning a 
considerable area of the ulnar surface of my wrist was 
greatly swollen and an intense itching occurs when the 
skin is touched, even though it be at some distance from 
the lesion. 
October 2U. The lesions have increased in size and have 
more of the appearance of small boils which have “pointed” 
and erupted slightly. There is considerable oozing of 
serous fluid, blood-stained pus and dark-colored matter 
which I believe is digested blood being defecated by the 
larvse. The exudate from the lesions is now sufficient 
to be quite disagreeable, owing to its staining clothing and 
bedding, and it is necessary to bandage all the lesions. 
It is to be regretted that the bandages were not applied 
earlier, so that the date of possibly a first molt of the 
larvse might have been noted. It is my opinion that this 
molt occurred about October 21, and that the small amount 
of discomfort present on October 19 and 20 was due to the 
larvse being in the first pre-molting period at this time 
and were not feeding and were quite inactive. Had the 
bandages been on the lesions at the time it is possible that 
some traces of the molted skins might have been found 
which would denote the time of the molt. 
October 26. There seem to be three kinds of local sensa- 
tions connected with the presence of the larvse. The first
