colour and tolerably thick. If an opening was made in the capsular 
wall and the capsule gently pressed with a finger or handle of a knife, 
the worm could be pushed out unharmed together with the surrounding 
fluid. An enormous number of the parasites were pressed out during 
the surgical operations, but they were nearly all injured. Fig. 2 shows 
the numerous capsules in the muscular tissue and the worm hanging 
out from the capsule. The specimens were obtained by p ulli ng them 
out with the utmost care from the uninjured capsules, making small 
openings on the walls, and then squeezing out the worms. 
Specimens of worms and capsules. The specimens of worms which 
were fixed in cold sublimate (at room temperature) or alcohol, under¬ 
went considerable shrinkage. At the suggestion of Prof. Ijima, I put 
some worms freshly removed from capsules, into slightly warmed 
physiological salt solution when they slowly moved and extended their 
bodies to the full length. These fully extended worms were then 
quickly transferred to hot sublimate ; and thus good specimens were 
obtained. Upon removing the capsules fri-.m the tissues they were 
fixed in cold sublimate or alcohol; large pieces of tissue—muscle and 
fat—were fixed in 6 % formalin, and the small piece in Muller’s 
solution. 
Size and shape of the worm. Various sizes and shapes of the worms 
are represented in figs. 1 and 2. It is noticeable that my specimens 
are very large in comparison with those from Case I. The largest 
specimen measures 75 x 2 mm. in length, a second 33 x 2 mm., both 
being in a somewhat contracted state ; a third specimen measures 
25 X 2 mm. in the contracted condition and a fourth specimen only 
measures 2x4 mm. The most remarkable point in the shape is the 
budding or branching. The division of the worm within the capsules, 
and the process of budding out and forming a supernumerary head, 
were described in detail by Prof. Ijima in the preceding case. But 
among my numerous specimens, there are various forms of budding 
which we could not find in Case I (fig. 2, h, /). The specimens repre¬ 
sented in fig. 2, /, and h, possess well developed buds or branches, 
and it is difficult to distinguish the original head from the super¬ 
numerary. The budding seems to take place in any part of the body, 
as represented in figs. 1 and 2. The size of the worm possessing the 
buds is also indefinite and we may find the buds on both small and 
large individuals. 
Extremities. The sucker-like or groove-like depression of the 
frontal end in many specimens is very conspicuous, especially in
