On examining sections from three different portions of the ileum, in ndditioo 
to the ordinary cysts containing large oesophagostome larvae, minute larvae of i 
nematode are found situated in various parts at the bawd wail. In one piece man? 
larvae are situated in the subperitoneal space, cut ti. 'onofea 
is lying stretched out, or again, a coil or two are tot) 
neighbourhood of the blood vessels, but none is Men within. In the second piece 
of gut, the large cyst invades the whole of the internal muscular coat, part of the 
external muscular coat and a portion of the submucosal space. Pirictlv under the 
muscularis mucosae but outside the cyst are seven portion - of minute larvae in cr: - 
section. In the third portion little sections of minute larvae are present in the 
external muscular coat and in some of the sections numerous cross-sections of larva 
are found in the deeper part of the submucosa. Weinberg* describes minute larva 
in the muscular coats of the large intestine, but they appear to be surrounded bva 
fibrous sheath which is not seen in any of the sections which I have examined. I 
submitted some sections to Dr. Weinberg.t but he was unable to give an opinio: 
regarding the cross-sections of these small larvae.

Ihis proves to be a very elongated submucosal cyst, occupying the entire space 
of the submucosa, and involving the inner half of the internal muscular coat, and 
an intermuscular cyst invading both muscular coats, and infiltrating but no; 
distending the subperitoneal space. The fibres of the muscularis mucosae axe 
somewhat atrophied and the mucous membrane displaced. 
Large mononuclears, polymorphonuclears and enormous vesicular cells, and a 
few eosinophiles with products of degeneration form the cell contents of the cyst: 
erythrocytes can only be found with great difficulty. Two transverse sections of the 
worm show many polymorphonuclear and a few mononuclear leucocytes in the 
interior of the intestine. The cyst walls are extensively infiltrated with mononuclear 
and JymphQit 1 cells; thick rows of eosinophiles occupy the middle layers and extend 
with the infiltration of mononuclears and small normal cells to the muscularis 
mucosae The internal muscular coat and intermuscular space show the same
