ECZEMA EPIZOOTICA. 
lesions ; often these young animals had dysenteric diarrhoea, 
with debility and emaciation,which became complicated 
with aphthae in the feet [cocotte), but on examination after 
death offered no traces of aphthae in the gastro-iiitestiiial 
tube. 
In adults aphthae were found in the mouth, progressing to- 
Avards cicatrization; the erosions were at times simply covered 
Avith a Avhite cheesy varnish, composed of non-agglomerated 
cells, and on other occasions with a real Avhite epidermis. 
But alongside of these cicatrising aphthae there Avere others 
of more recent origin, and still in an ulcerated condition; 
sometimes vesicles still entire were found. The latter were 
rarely met with in the mouth; but they were observed on 
the palate, in the pharynx, on the muffle, in the nostrils, and, 
lastlv, even on the mucous membrane of the true stomach 
•/ •' _ 
and duodenum. They Avere never seen in the larynx, trachea, 
or oesophagus, as some writers say they have been. 
The epithelium of the reticulum was easily removed, and 
showed the mucous membrane highly injected, and covered 
Avith reddish violet patches, measuring from f to inches in 
diameter, where the membrane looked as if eroded, and its 
superficial surface as if cut by a stamp. The same patho¬ 
logical alteration was seen in the mucous membrane of the 
third and fourth compartments of the stomach and in the duo¬ 
denum, though in a variable degree. The erosions in the 
true stomach Avere most marked. The food in the stomach, 
especially in the third compartment, Avas dry, and everywhere 
the epithodium was readily detached in removing the con¬ 
tents. In the rumen there Avere usually ecchymotic patches, 
larger than those in the reticulum, but no erosions. 
The intestines only showed some reddish spots, whieh Avere 
more evident in those portions near the gastric viscera. On 
cutting into them, they Avere found to be full of mucosities, 
Avithout any traces of food, and showing, as in dysentery, 
evidences of subacute inflammation. On the mucous mem¬ 
brane of the duodenum and part of jejunum, in addition to 
the aphthous erosions just mentioned, and Avhich w^ere of 
small dimensions, there Avere observed numerous liiemor- 
rhagic patches projecting beyond the level of the mucous 
membrane, coloured a deep red, and punctated on their 
borders. 
The spots corresponded to the orifices of the glands of the 
mucous membrane—the mucous follicles—particularly those 
of Brunner and Peyer, Avhicli Avere hypertrophied, and the 
seat of a special inflammation, Avith capillary haemorrhage 
into the surrounding tissues.
