One side of the microscopical section is covered by 
stratified squamous epithelium, whose dense fib- 
rous submucosa is infiltrated by lymphocytes. 
Passing down from the submucosa a delicate, 
lace-like matrix is encountered, consisting of 
sparsely placed spindle cells, with intervening 
delicate pink reticulum. The bloodvessels are 
numerous and of capillary type. No hemorrhages 
or necrosis. In this matrix lie uniformly disposed 
trabeculse of dense pink hyaline material, with 
lacuna and contained cells. In a few places giant 
cells are applied to the sides of such trabeculse. 
In a few cases the trabeculse contained very fine 
blue granules. 
2850. Indian Paradoxure {Paradoxurus niger) : 
Adenocarcinoma of pancreas. 
Grossly, the pancreas was very pale. In the head 
there is a hard nodule of the same color as the 
pancreas and about the size of a pigeon's egg. 
The microscopical section shows in the margins nor- 
mal pancreas, with islands of Langerhans. Bulk 
of section consists of cells which are not nearly so 
granular, and hence not so deeply-staining, as 
normal tissue. Some of these cells are distinctly 
arranged into ducts with lumina but the general 
tendency is to run into diffuse collections with 
no acinus formations. This diffuse arrangement 
of cells penetrates between the normal pancreatic 
acini which border on the tumor. This takes 
place in such degree that in places normal acini 
are completely isolated in the tumor cells. 
Respectfully submitted.
