occasions, but was unable to detecg any lilarial embryos. 1 also 

 punctured the inguinal glands with a hypodermic syringe, but 

 hère again examination of the fluid gave a négative resuit. I may 

 State, however, that at thaï time, OAving to pressure of olher work, 

 I v^^as unable to dévote as much time to the examination of the 

 blood as I should like to hâve done, and it is possible that a more 

 fréquent examination, moreespeciallyatnight, would haverevealed 

 the présence of embryos. So far then, apart from the présence of 

 the Filaria which I am about to describe, there do not appear to 

 hâve been any distinctive features in the case. 



TuMOUR. — It was about one inch in length by three-quarters in 

 breadth. On making an incision, a greenish, semi-purulent locking 

 fluid about the consistence of cream escaped from the cyst. This, 

 on microscopic examination, was found to contain numerous 

 tilarial embryos. The capsule of the cyst consisted of dense fibrous 

 tissue, lined internally by a layer of soft caseous looking material, 

 which could be easily scraped ofï and was composed of granular 

 matter, fat cells, flat nucleated epithelial cells. It contained free 

 embryos. The interior of the cyst was filled with the adult Filariae, 

 lying in loops, twisted up in the most confusing fashion; entering 

 the cyst walls, runningalong shallow channels, and then reentering 

 the cyst. Owing to this and to the softness and brittleness of the 

 Worm, it was a matter of the greatest difTiculty dissecdng it out, 

 and Ifound it impossible to do so without breaking it. Eventually, 

 however, I succeeded in isolating a complète unbroken adult 

 maie, and the head, tail, and intermediate fragments oi a female. 

 Thèse two formed the whole contents of the cyst. 



Mâle worm. — He is of much smaller and narrower dimensions 

 than the female. Length of one spécimen 3°™025, of the other S^^n^oss. 

 It is Avhite in colour, and somewhat flattened in shape, which is 

 possibly artiiicial, and due to immersion in the preserative. The 

 chitinous cuticle, which is about 18 [j^ inthickness, is very distinctly 

 striated throughout, the striations becoming tîner as they approach 

 the head and tail. The greatest diameter of the body is 144 p., which 

 is maintained throughout the greater part of its course. There is a 

 gentle and uniform taper to head and tail. Diameter at head 44 [x. 



The head (fig. 1) is rounded and not club-shaped. The mouth is
