November 26. No. 3 gave numerous twinges of pain dur- 
ing the day and pus continued to ooze at times from the 
two extra openings in this lesion. There has been very 
little movement felt at Nos. 1 and 5 today. This evening 
the bandages were left off for a time and the larvae were 
observed with a lens. Both these larvae could be seen 
working vigorously enlarging the apertures to the lesions. 
This was done entirely by the spines on the posterior seg- 
ments. They were rubbed against the side of the hole 
with a rasping motion, and this was carried on at first 
one side of the hole and then the other. It reminded one 
of enlarging a round hole with a round file. At intervals 
of from five to ten minutes each of the larvae protruded 
from its hole for more than a quarter of an inch as though 
testing the diameter of the opening to see if it be large 
enough to permit the emergence of the larger anterior end. 
After protruding for a few minutes the larva withdrew 
within the lesion and again began its rasping on the edge 
of the opening. This continued for about three hours, 
when the bandages were again applied. There was con- 
siderable movement in No. 5 today and the escape of pus 
and digested blood from this lesion was sufficient to soak 
through the dressing twice during the day. 
November 27. Larvae Nos. 1 and 3 were quiet and gave 
very little trouble during the night, but this morning they 
became active and protruded so far that it was thought 
that they were about to emerge. No. 3 continued more or 
less movement during the early morning and the dressing 
was removed several times to see what was taking place. 
At each time the larva was partly out of the hole, but 
it always withdrew again after coming out about so far. 
At 10 A. M. a movement was felt on my skin at the lesion 
and upon examination the larva was found to be coming 
out. It appeared to be doing very little struggling, yet 
it slowly came from the hole and dropped over on my arm. 
November 28. Larva No. 1 seems to be dividing its time 
between protruding for about half an inch and working 
very industriously at enlarging the hole, although the latter 
is now fully 5 mm. in diameter. 
November 29. While I was taking a shower this morn- 
ing, larva No. 1 protruded for nearly half an inch for a
