a disease but as secondary, or rather symptomatic of some 
distinct and acknowledged genus or species of disease. We 
believe it to be occasionally present as a symptom of acute 
laryngitis ; nay, in the most severe forms of that disease, we 
believe it to be by no means an unusual accompaniment; 
and we give Mr. Haycock the credit of bringing it, as such, 
before the notice of Veterinarians, by most, if not by all, of 
whom, it has been omitted to be noticed; or, if noticed, to 
be mentioned. We annex Mr. Haycock’s account of it 
(stopping short at the homoeopathic treatment) verbatim :— 
“ Spasm of the Larynx . 
“ It is somewhat surprising that an affection possessing the 
importance of the one which I shall now treat upon should, up 
to this hour, be without place, and in truth without mention, 
in our systematic works professing to treat upon veterinary 
medicine and veterinary pathology; yet such is the truth—a 
truth which becomes the more surprising when we find that 
the omission cannot be said to arise from the want of data 
whereon to assign it a place in our literature; for the 
volumes of c The Veterinarian ,’ and the ‘ Veterinary Record ,’ 
published during the last ten years, to my certain knowledge, 
abound with facts attesting the actuality of the disease. 
This affection may with propriety be regarded as one of 
those sequences greatly to be dreaded during the acute stage 
of laryngitis and strangles. It may arise from inflammation, 
or irritation going on within, or directly acting upon the 
larynx itself; or from a distant source of irritation acting 
upon the organ from an impression conveyed in a reflex 
manner by one or more of the numerous nerves which 
terminate within the tissues of the laryngeal apparatus. 
“Symptoms. — The symptoms of spasm of the larynx are of 
so evident a nature as to warrant me in saying that they de¬ 
clare themselves, and that too in the most decisive manner. 
Sometimes the disease manifests itself in a moment, as it 
were, with a most terrible severity—the animal begins to 
gasp for breath—the eyeballs protrude and present a wild 
haggard appearance—the nostrils are dilated to their utmost 
extent —the nose is protruded, and the neck is carried in a 
line with the back—the flanks heave with most excessive 
. iolence, and every time the poor beast inspires air, a sound 
is emitted which will vary in its character and intensity, 
according to the vigour of the spasm. Sometimes it will be 
loud and shrill, sometimes a kind of scream, at other times
