[December 
attacks lasted from one to three minutes each time they 
occurred. Squeezing the arm just below the lesions seemed 
to stop the pains to some extent. These two lesions bled 
sufficiently to stain through the bandages several times 
today. 
November 3. Drops of apparently 'unchanged blood 
oozes at intervals from Nos. 1 and 3 when the bandages 
are removed. Blood-stained serum is exuding from Nos. 
2, 4 and 5. No pus is in evidence except a small amount 
from No. 6. When viewed with a lens at this time each 
larva may be seen pushing liquid from the hole with a 
quick, pushing, upward movement somewhat after the ac- 
tion of a plunger of a pump. The downward movement 
seems to draw back some of the fluid with each jerking 
back of the posterior end of the larva. When the end of a 
larva is retracted an occasional air bubble can be noticed 
coming up through the liquid. There has been very little 
pain or irritation caused by any of the lesions today. 
November U* A sharp pricking lasting several minutes 
has occurred at intervals during the day and early evening 
in No. 6. This lesion and the area surrounding it is quite 
red, considerably swollen and very sore to the touch. 
At about seven o’clock this evening when the bandages were 
removed for a while this larva was found to be pushing 
out a cast skin. The larva had molted, and since it prob- 
ably needed more room in the hole for its future growth, 
was disposing of the cast skin. The movements of the larva 
caused the skin to emerge in its natural, round, tube-like 
form. As it came slowly out it formed a tiny crater about 
2 mm. high around the hole and then continued to turn 
back upon itself with the posterior end of the larva pushing 
up through the center. From the manner in which the 
molted skin moved slightly from side to side it appeared 
as though the larva was pushing it up first at one side 
and then at the other, but keeping it about even so that 
the rows of hooks of each segment were all out before 
those of the next segment appeared. After observing the 
efforts of the larva with a hand lens for about three hours, 
it was estimated that about one-third of the cast skin was 
still in the hole. None of the other five lesions have 
caused very much discomfort.
