TODD AND WOLBACH. 
Three other lymph glands are also negative except for a large amount of 
brown pigment in phagocytic cells. 
One bronchial lymph gland is negative. Another bronchial lymph 
gland which, at the autopsy, was seen to be spongy and to contain air- 
filled cavities, has many round and oval cavities with smooth lining of 
flattened or cuboidal cells. There are many giant cells around these 
cysts. The intervening tissue resembles fibrosed lymphoid tissue and 
contains some carbon pigment. Tissue from swollen leg : Consists of 
dense 'fibrous tissue with numerous blood vessels surrounded by lymphoid 
and plasma cells. Brain cortex: Normal. Spinal cord: Normal. 
Pituitary body : Normal. 
Horse II. (Chestnut Gelding). — Weight, 960 pounds; age, 6 (?). 
This horse was inoculated intraperitoneally on February 4, 19 10, with 
30 cubic centimeters of blood from the Grey Gelding (temperature 
100.40 F.) Twelve days later the temperature commenced to rise and it 
rose steadily until, on the fifteenth day, it reached 106.1° F. ; after two 
days it fell to between 100° and 102° F., where it remained for ten days, 
when it again rose to 103° F. For six weeks the temperature was exceed- 
ingly irregular; at intervals of ten days there were three rises to 103.50 F. 
with pulse rates of from 38 to 44. At this time the horse was much 
weaker; it weighed only 845 pounds, and the temperature, while still 
irregular, remained between 990 and loio F. Anemia was not marked 
(red cells, 5,360,000; white cells, 16,200). During the last three weeks 
of its life the horse was extremely weak, although it fed and drank 
readily until its death. No edemas nor petechias were seen. For one 
day before it died it was unable to rise. It died during the night of 
May 12. 
Autopsy : (a) Gross appearances. — The autopsy was commenced 
within twelve hours after death. Rigor mortis was present, but the 
organs were distinctly warm. 
The coat is rough. There are no edemas. The animal is extremely 
thin; the muscles seem normal. A few adult filariae (Filaria papillosa) 
lie among the coils of the intestine. There are no petechial hemorrhages 
on the peritonium and the cavity does not contain an excessive amount of 
fluid. The pleural cavities each contain about 500 cubic centimeters of 
clear yellowish fluid. 
Heart (yi pounds) : The muscle is distinctly pale and seems cloudy. 
The pericardial fat is edematous and infiltrated with a gelatinoid, yellow- 
ish edema. The heart valves and great vessels are normal. Lungs 
(right, 10?^ pounds; left, pounds): Both lungs are congested and 
slightly edematous. The right lung is the more congested of the two and, 
in one small area, there seems to be an extravasation of blood. Liver 
(17 pounds) : With the exception of a few scattered spots, which are 
paler than the remainder of the organ, the liver seems to be normal. 
Kidneys (together 4 pounds) : The substance seems to be normal.
