Plerocercoides prolifer Ijima 
assumed that they are identical wdth the proliferating cestode larvae 
found in Cases I and 11. 
The worms in Case III are almost all small in size, and possess few 
buds or branchings. The size and shape of the worms is nearly the 
same as in Case I, but is very different from those in Case II. Hence 
there is no need to mention the external features and internal structures 
of the worm in Case III. 
History of Case III (supplied by Mr Inoue). The patient is a man 
57 years old, Kyukichi Ohyabu by name, living in Kyoto. About 
13 years previous to his coming to the hospital, he discovered acci¬ 
dentally a few nodules in the skin of the inner side of the right thigh. 
Since then the number of nodules gradually increased and they were 
found in many other parts of the body. The nodules varied in size. 
In the earlier course of the disease, he felt itching of the skin at the 
seat of the nodules, and he sometimes noticed a white vermicular mass 
scraped out by his own scratching. 
He entered the University Hospital on 30. v. 1911, to obtain treat¬ 
ment for a remarkable swelling of the right lower limb. The patient 
was well nourished and in a healthy condition except for the presence 
of a hernia inguinalis on the right side. In all parts of the body, with 
the exception of the head and face, we found the numerous nodules 
of varying sizes, some of them standing out from the surface of skin, 
and others imbedded in the subcutaneous tissues. The former were 
indicated by the swelling of the integument, and by the thinning out 
and pigmentation of the cortical layer of skin ; the latter were of hard 
texture and easily recognized by touching the skin. It was easily 
observed, as in the preceding cases, that the vermicular nodules slowly 
changed their positions, according to the movement of the worms 
through the subcutaneous tissues. 
The swollen portion of the right thigh gave the appearance of 
elephantiasis, and the swelling was evidently caused by an accumula¬ 
tion of pus in the subcutaneous tissues. On removing the pus, the 
swelling gradually diminished and ultimately disappeared. He left 
Hospital 21. vii. 1911 when the swelling was cured. 
On 30. V. 1913, however, he returned to the Hospital on account 
of recurrence of a more serious swelling of the right thigh. He now 
appeared well nourished and seemingly healthy, except for this 
swelling. Vermicular nodules, cutaneous and subcutaneous, were, 
however, found in all parts of the body and were considerably more 
numerous than before. As formerly, the swelling was easily cured by
