had, during a long time, resisted all the means that we had 
used, we may, perhaps, mention a singular case of vertiginous 
disease. 
The patient was turned into a stall between two pillars, and, 
for a month, was condemned to the most complete abstinence 
from solid food ; the least movement of the mouth having uni- 
formly determined a renewal of the haemorrhage. 
He one morning presented symptoms of vertigo. Sometimes 
he threw himself forward on the straps by which he was retained, 
at other times he threw himself backward, straining his halter 
with the greatest violence. The slightest noise produced a more 
violent effort to break from his confinement. The introduction of 
the smallest portion of light into the stable suddenly determined 
a considerable access of the complaint. The pupil was largely 
dilated, but the breathing calm ; the pulse almost normal, and 
the mucous membrane apparently without injection. He had 
neither heat nor sensibility on the cranial region. 
Similar symptoms have already been observed under the same 
circumstances, and attributed to inflammation of the arachnoid 
membrane, consecutive on that of the jugular. In the case of 
which we now speak, the absence of every sign of general inflam- 
matory action and of all febrile movement does not permit us 
to admit the existence of an arachnoid inflammation. We 
rather think that the phenomena that were produced were attri- 
butable to a cerebral action, determined by the state of vacuity 
of the intestinal canal. It is known that, in man, abstinence 
too prolonged produces singular ecstatic phenomena and hallu- 
cination of the senses. The horse was turned again towards its 
manger, and oats were given him, which he devoured with avidity : 
fortunately, the clot of blood being sufficiently solid to resist the 
movement of the jaws. When the digestive action was called into 
play, the nervous phenomena entirely ceased. 
Several cases have been cited of cerebral arachnoiditis, com- 
with ulceration of the veins, and which are thus ex- 
in the Legs . — Our old authors speak of the danger of 
the repercussion of the suppuration after the sudden suppression 
of the secretion of water in the legs. There is a fact on record 
which comes to the support of this opinion. 
A horse, of good constitution in other respects, was conducted 
to the school to be treated for water in all four legs, and of long 
continuance. The skin, very deeply afflicted, was covered on the 
posterior part of the canons with those red grapy granulations 
which appear in the last degree of the disease. 
The secretion which was formed between these granulations
