Loupinj-lll in Sheep. 
cirrhotic (indurated), and the bile ducts contained numerous living flukes. 
Some of the mesenteric glands were enlarged, indurated, and gritty on section. 
The bronchial glands were in a similar condition. The lungs contained some 
pseudo-tubercles, and there was a quantity of dropsical fluid in the pericar- 
dium. The blood was examined microscopically for micro-organisms, but 
none were found. 
Case IV. — The carcass of a lamb, hilled two hours previously as a hope- 
less case of louping-ill. The skin had been removed before it was brought 
to me, and unfortunately no history of its illness was obtainable. 
Post-mortem. — This revealed no abnormality of any importance, save the 
presence of a ball of bard grass mixed with wool in the fourth stomach. A 
microscopic examination did not reveal any bacteria in the blood. The 
blood and spinal cord of this lamb were used for the inoculation of 2 lambs 
( see Experiment 1). 
Case V. — A lamb about 3 or 4 weeks old, said to have been unable to 
stand for a fortnight. The paralysis affected the hind limbs only. Killed 
by bleeding. 
Post-mortem. — A number of ticks were adherent to the skin. The spleen 
contained six pea-sized abscesses with tough yellow pus. A similar abscess 
was present under the latissimus dorsi muscle, and another between the 
bodies of the third and fourth lumbar vertebrae ; the latter bulged into the 
spinal canal and pressed on the spinal cord. Pus from these abscesses 
showed under the microscope numerous staphylococci, and cultures of the 
same were obtained from the spinal abscess (see Experiments with cultures). 
The brain was not examined. 
Case VI. — The carcass of a ewe, found dead the same morning, and sent 
as a case of louping-ill. The abdomen was distended with gas, and putre- 
faction was already well advanced. The liver and kidneys were almost 
pulpy in consistence, and the lungs were congested. The case appeared to be 
one of “ sickness ” or braxy, and the brain and spinal cord were therefore not 
examined. 
Case VII. — The carcass of a lamh which had died on an adjoining 
farm. The skin had been removed before it was brought for examination, 
but it was said that some ticks were present. The lamb had been unable to 
stand for 4 days previous to its death, owing to paralysis of its hind limbs. 
Post-mortem . — One pea-sized necrotic area in the liver. The fourth 
stomach contained a mass of dried grass mixed with wool. Some congestion 
of the coverings of the spinal cord in the cervical region ; surface of brain 
abnormally moist. 
Case VIII. — A ewe. Been unable to stand for some days. Lies on side 
with neck stretched, head resting on ground, and both fore and hind legs 
extended. No convulsions had been noticed. Consciousness appeared 
unimpaired, and the legs were moved freely when pricked with a pin. 
Killed by bleeding. 
Post-mortem. — Fairly numerous pseudo-tubercles iu the lungs. Cerebro- 
spinal fluid taken at the foramen magnum was used for inoculation (see 
Experiment 3). No bacteria could be found in the blood on microscopic 
examination. 
Case IX. — A yearling ewe, which had been unable to stand for 12 days. 
Position exactly the same as in the previous case. There appeared to be 
no impairment of either sensation or consciousness, and at intervals both 
fore and hind legs were moved backwards and forwards. Killed by 
bleeding. ' 
Post-mortem. — A few pseudo-tubercles in the lungs. Cerebro-spinal
