Loujping-Ill in Sheep. 
fluid in excess both in spinal canal and cranial cavity. Some of this fluid 
was used for inoculation (see Experiment 2). No bacteria were discoverable 
by the microscope in either the blood or cerebro-spinal fluid. 
Case X. — The carcass of a lamb which bad been taken ill on the pre- 
vious day, and had died 3 hours before my arrival at the farm. The owner 
stated that it had shown symptoms of brain disturbance, and lo3t the power 
of its legs. 
Post-mortem. — There were a few ticks on the skin. The mucous mem- 
brane of the small intestine was congested, and there were some spots of 
extravasation in the wall of the duodenum. The fourth stomach contained 
a considerable quantity of fine sand adhering to the mucous membrane. 
The spleen was swollen and the consistence of its pulp was diminished. The 
kidneys were congested. The pericardium contained about 2 ounces of 
clear, almost colourless, fluid. Numerous small spots of blood extravasation 
were present in the muscles of the back and loins. No bacteria were dis- 
coverable by microscopic examination in the spleen or blood. 
Some of the pericardial fluid was used for inoculation (see Experiment 5). 
Case XI. — The carcass of a lamb several weeks old. Died a few hours 
before my arrival at the farm. 
Post-mortem. — Numerous ticks on skin. Violent inflammation and blood 
extravasation at their points of attachment. Intense inflammation of the 
large intestine, with extravasation of blood into the lumen of the bowel. 
The fourth stomach contained a ball of dried grass and wool. Spleen slightly 
enlarged and softened. Liver pale. Lungs and kidneys congested. The 
brain was slightly osdematous. Neither blood, spleen-pulp, nor cerebro- 
spinal fluid showed any bacteria when examined microscopically. Blood 
from the heart was used for inoculation (Experiment 7). 
Case XII. — The carcass of a Iamb, several weeks old, found dead and 
brought the same day for examination. It had been first noticed ill on the 
previous day — unable to rise, but frequently struggled. 
Post-mortem. — No ticks on skin. Abdomen tympanitic from putre- 
factive decomposition. Stomach ruptured, apparently post - mortem. 
Kidneys pulpy. The other organs were not examined. 
Case XIII. — The carcass of a lamb brought 24 hours after death. Been 
ill for 24 hours. 
Post-mortem. — Putrefaction had not made so much progress as in the 
preceding case, although a longer time had elapsed since death. No ticks 
on skin. Small bowel congested. Spleen swollen and softened. The 
fourth stomach contained a compact mass of dry grass, wool, and sand. 
Kidneys somewhat pulpy. Brain and cord not examined. 
Case XIV. — A lamb about a month old. Had been ill for about a 
week, and unable to get up. Lies on side, sometimes holding the head up, 
and at others resting it flat on the ground. No evidence of impairment of 
sensation or consciousness. Sucks the finger, and can stand for a little when 
placed on its legs. Killed by bleeding. 
Post-mortem. — No ticks on skin. A small quantity of fluid in the peri- 
cardial sac. A marked excess of fluid in the cranial sub-arachnoid space", 
and brain tissue somewhat oedematous. The pericardial and cerebro-spinal 
fluids, and the blood, were used for inoculation (Experiments 4 and 8). 
Case XV. — A lamb about a month old. It had died about 2 hours 
before my arrival at the farm. Its illness had lasted for 4 days, during 
which tim9 it “ lay and trembled.” 
Post-mortem. — The fourth stomach contained a ball of grass and wool. 
Spleen a little enlarged. A small quantity of fluid in the pericardium,
