ANALYSIS OF CONTINENTAL JOURNALS. 
mucous membranes, which are hardly modified in their phy¬ 
sical characters. On the third day all the symptoms are 
greatly aggravated, the eyes are inordinately dilated, 
amaurotic, and half covered by mucus adhering to the lids ; 
the nasal openings are obstructed by dried mucous secre¬ 
tions, the beak is dirty, locomotion uncertain and automatic, 
the crest pendulous, either discoloured or purple. The 
spots on the tongue appear like ordinary sized warts, of 
a greyish colour; these little bodies are found covered with 
membranous fragments bearing some analogy to the secre¬ 
tion of croup. The whole of the mucous membrane is now 
discoloured and wan, like the tongue. The patient is 
prostrate. The morbid productions soon invade the whole 
of the organs of deglutition, they are of an unusual 
size, which renders them immovable, completely preventing 
deglutition, by nearly closing the opening of the pharynx 
and larynx ; asphyxia has become imminent. Thus, from 
the second day, the alterations of the mucous membrane of 
the tongue predominate over the other symptoms, which are 
evidently only the consequence of the first. Tliese lesions 
completely distinguish this affection from the epizootic ob¬ 
served in the north sitice l8ol. 
In the autopsy on the number of subjects I have examined 
I have never found anything which resembled the morbid 
appearances so accurately described by M. ffenault, and 
which led this learned pathologist to describe the malady 
as the cholera of fowls. The lesions which we have already 
described affect the bucco-laryngeal and pharyngeal mucous 
membrane, and consecutively all the muscles of the tongue. 
The mucous membrane is found to be pale, thickened, in¬ 
filtrated, covered with a sort of gummy varnish and frag¬ 
ments of false membranes. The fibres of the external 
muscles are discoloured and softened. The epidermis which 
covers the papilla and follicles is elevated. The fibres of the 
outer muscles show less alteration than those of the internal. 
The hypertrophied parts of the papillae and follicles 
resemble granular vegetations ; they are without any consis¬ 
tence, and unprovided with epithelium. The oesophagus is 
wrinkled, and of a pale silvery colour; this alteration extends 
through the whole of the digestive organs. The crop only 
contained a few grains of sand ; the ventricle, gizzard, and 
intestines are empty; the larynx discoloured and covered 
with thick mucus; the lungs pale, but without alteration. 
The other organs show no alterations, with the exception 
of the liver, which is slightly atrophied. 
Diagnosis .—The seat of the malady is in the buccal,
