They were sent to Alfort the same evening, arriving there 
the morning of the ioth. 
A utopsies. 
Cow No. j .—The lungs, the pleura, the pericardium, the 
bronchial and mediastinal glands are absolutely sound. The 
liver is affected with distomatosis to a slight degree, but its 
ganglions are normal ; the same of the spleen, the kidneys, the 
pancreas, the uterus, and all the lymphatics of the abdominal 
cavity. The mucosa of the mouth, the velum of the palate, the 
pharynx, the larynx, the subglossal and retropharyngeal gang¬ 
lions present no noticeable alteration. 
The intestine is opened its entire length ; on the mucosa of 
the ilium are found numerous pisiform nodosities filled with 
greenish pus or suppuration. They are probably parasitic. 
The only suspicious lesion found is at the beginning of the 
large intestine ; the mucous membrane appears thickened, to be 
infiltrated, the congested parts being more compact than else¬ 
where ; portions of the mucous membrane are removed and put 
in absolute alcohol for bacteriological examination. 
This examination has shown a pronounced leucocytic in¬ 
filtration of the deep strata of the mucosa, such infiltration ex¬ 
tending between the glandular culs-de-sac; but it was impossi¬ 
ble to find a single Koch’s bacillus. This autopsy has not revealed 
the tubercular lesion which caused the tuberculin reaction. 
Cow No. 4 .—The viscera of the thoracic and abdominal 
cavities do not present any tubercular lesions. However, we 
preserved for histological examination several Peyer’s glands 
which appear thickened and granular. The mucous membrane 
of the mouth, the velum of the palate and the pharynx are ap¬ 
parently sound, but the retropharyngeal ganglions are enlarged, 
filled with a serosity and evidently infiltrated in their cortical 
layer with tubercular granulations. The tubercular nature of 
the ganglionic lesion has been confirmed by the bacteriological 
examination ; not so with Peyer’s glands. The cellular infil¬ 
tration of the deep layer of the mucosa did not show Koch’s 
bacillus.
