The development of this opening in the center of the lesion 
is evidence that these extra openings are due to ulceration. 
November 21. Serum and pus with a very disagreeable 
odor is exuding from all the lesions at this time. At No. 3 
the anal end of the larva is visible in the opening and the 
stigmal plates may be seen. The larva in No. 6 has been 
protruding from the opening about a quarter of an inch 
all day, regardless of whether the bandage is on or not. 
When the bandage and gauze are in place the protruding 
end of the larva makes a sort of a small burrow in the 
gauze pad. Several times during the day the larva 
twisted about rather vigorously as though it might be 
about to emerge. 
November 22. The larva in No. 6 still remains with 
its posterior end protruding from the hole the greater 
part of the time. The pain from this lesion becomes so 
intense at times that it is almost impossible to walk until 
the paroxysm is over. These pains (although of frequent 
occurrence) are, fortunately, of short duration. Blood and 
serum issues from the new opening after each of these 
attacks. The larva in No. 3 seems to be enlarging the 
opening in the lesion today. 
November 23. Larva No. 6 is still twisting about quite 
frequently and causing considerable pain. It continues 
to have its posterior end outside the hole and burrowed 
into the dressing during the greater part of the time. The 
dressings are very loose and would not prevent the larva 
from emerging. The dressings are removed frequently but 
the larva makes no attempt to come out any further when 
they are off. With the exceptions of Nos. 5 and 6 all the 
larvae seem to be enlarging the apertures to the lesions. 
There is considerable discharge of serum, digested blood 
and pus from No. 5 today. The feeling of lassitude still 
continues and short spells of slight fever seem to occur 
at intervals. I am still being awakened many times during 
the night by the larvae. 
November 2U. The posterior end of the larva in No. 2 
protruded from the hole about a quarter of an inch this 
morning. When viewed with a lens the larva could be 
seen enlarging the hole by means of a rasping movement 
of the spines on its posterior end. The hole is now about
