IG 
ON VEKTIGO AND PARALYSIS. 
and have occasionally puzzled the junior student, and a little 
startled and displeased the more experienced practitioner. 
I may be permitted to give a few illustrations of this. Mr, 
Blaine, in the index to his truly valuable “ Outlines,” directs us, 
under the head Vertigo, to a page where he is treating of “ symp¬ 
tomatic phrenitis.” He very properly regards it as a symptom of 
disease, and nothing more. 
Our classical as well as scientific writer, Mr. Percivall, uniformly 
refers these external manifestations to particular morbid states 
of the brain and its associated organs.” 
The talented author of that standard work The Horse” glides 
over “ the stream of nervous affections,” without mention of it as a 
distinct disease. The author of the “ revised” work of Clater, in 
which I fancy I can trace the graphic pen of my friend The 
Horse’s” owner, principally, or I believe only, mentions it under 
the head “megrims, or a sudden congestion of blood in the vessels 
of the brain.” 
Mr. White speaks of it as the effect of “ water in the cranial 
cavity,” “ congestion of the brain,” or as being connected with 
over-distention of the stomach and bowels. M. Ollivier, M.V., 
in a case which he sent to the Journal Vet. du Midi, speaks of 
vertigo as being symptomatic of cerebral disturbance and gastric 
derangement. 
On the other hand, all those pilfering writers with which the 
press has lately teemed, strangely confound the mere symptoms of 
disease with the actual morbid state of the organ. Rydge, who in 
many respects deserves to be better associated, is flagrantly guilty 
of this in his “ Manual,” and has either the carelessness or the 
ignorance to co'nfound megrims with epilepsy. After attempting 
to depreciate the opinions of others respecting its nature, he pur¬ 
loins a passage from the author whom he abuses, gives that 
author’s opinion as to the treatment of the disease, and then, with 
some tact, leaves the subject altogether. 
I must not, however, include in my censure that inestimable 
writer, who has, in the last volume of The VETERINARIAN, in¬ 
troduced a case which he entitles “Vertigo in a Stanley Crane;” 
for he has this excuse (and a valid one it is), that the patient got 
well under his treatment, and he was, consequently, unable to 
point out the precise morbid affection of the brain which was the 
cause of the vertigo. 
On the whole, Ave must be led to regard vertigo, lethargy, &c., 
as only the manifestation of impaired function of the brain, occa¬ 
sioned either by direct organic lesion, or by sympathetic influence. 
Craving pardon for these not quite inappropriate observations, 
I beg to communicate the record of a disease which occurred in
