“ Symptoms.— As to the symptoms produced by the worm, 
whilst Rudolphi found a dog which he examined perfectly 
well, and Dujardin, Miram, Colin, etc., make no reference to 
any disorder in their cases; on the other hand, Chobart 
gives rather a dark account of the effects produced. ‘The 
animal,’ he says, ‘is subject to convulsions, during which it 
is violently agitated, stops short, hits itself on the head, 
rolls over, rubs its nose on the ground, and the jaws are 
convulsively champed. It devours everything within reach, 
such as wood, straw, etc., discharges a large quantity of 
saliva, passes urine involuntarily, and sneezes without 
ceasing. Death sometimes ensues.’ 
“The mucous membrane of the nose is found to be red, 
blackish, ecchymosed, thickened, and ulcerated ; the sinuses 
more or less filled with pus; and even the ethmoid bone 
sometimes partially carious. 
“ Tvreatment—Trephine the nostrils and inject pick water. 
Inhalations of chlorine and tobacco smoke. Chloroform?” 
ASTHMA (CONGESTIVE). 
This disease is due to congestion of the mucous mem- 
brane of the bronchial tubes,and chiefly affects aged, highly . 
fed, pampered house-dogs, and those in the same condition 
out of doors. 
Predisposing causes.— Hereditary disposition, indigestion, 
gastric and intestinal irritation. 
Exeiting Causes.—Sudden changes of temperature ; flatu- 
lency ; obstructed pneumonic circulation ; large accumula- 
tions of fat, especially about the heart and large blood- 
vessels ; pungent effluvie, especially ammoniacal: hence 
dogs continually kept in foul stables being asthmatical. 
- Symptoms. — Thick, laboured, wheezing respiration ; 
husky bark ; distress after exertion, with excessive panting, 
and frequently palpitation; Schneiderian membrane in- 
jected ; flatulency and constipation.
