DISEASES OF BLOOD AND BONE MARROW 107 
swells slightly, with prominent striae. Intestines throughout are pale 
on serosa. Wall thin. Mucosa flat, pale pink. Contents creamy mucus 
in the upper intestine. Large intestine contains large masses of very 
firm feces. Cecum is distended with feces and a great quantity of 
nematode worms. They are not attached to mucosa nor does mucosa 
seem altered because of their presence. Skeleton and muscles. — Long 
bones of extremities break easily, but with snap. Skull can be dented 
Avith fingers. Bone marrow of femur bright red. 
Microscopical Notes. — Liver shows moderate degree of fatty degen- 
eration with capillary congestion. Kidneys negative. Some postmortem 
change in last two organs. Spleen, marked congestion. Hyperplasia of 
large lymph cell type, particularly in follicular centres. Blood destruc- 
tion moderate. Bone marrow seen in condition of marked activity of 
myeloid type. Aside from enormous crowding of strands there does not 
seem to be any atypical cell. Intestines show practically no change. 
Sam6 condition holds in pancreas. In several places in pancreatic ducts 
cross sections of nematodes may be found. In among lobules of pan- 
creas is a well encapsulated cellular mass without particular architecture. 
It consists of cells of large lymphocyte or endothelioid series. There are 
numerous cells of size and staining characters of small lymphocytes. 
There are no megalocytes but there are some indistinguishable from 
myelocytes. This may be an intrapancreatic lymph node. One small 
lymph node found in section; it shows a picture quite like the marrow 
except for megalocytes. Blood vessels do not show an excess of leuco- 
cytes in free or coagulated blood. 
Perhaps tliis latter case belongs to the aleucemic 
leucemias or pseudoleucemias. These two conditions are 
recognized by the difference in circulating leucocytes, a 
piece of information not at our disposal. The whole sub- 
ject of hemato-lymphatic affection must remain unsettled 
in so far as a diagnostic name is concerned, for in very 
few cases has the blood of our animals at autopsy been 
in a state permitting reliable observations upon stained 
smears, because of coagulation, lysis or decomposition. 
After considering a few more of the diseases of the blood 
and marrow, the lymphatic apparatus will be considered. 
But there is a borderland to which a word might be 
devoted at this time, that group to which various names 
— Hodgkin's disease, pseudoleucemia, general adenop- 
athy, adenie, aleucemic leucemia — have been applied 
and which has been accepted as occurring in the domesti- 
cated animals. Since I have been occupied for several
