MM. NOCARD AND ROSSIGNOL. 
Cows Nos. i and 2 were kept until July 1st, when they were 
sent to Alfort and killed and autopsied. 
The tubercular infection did not begin to manifest itself in 
Cow No. 2 until the 21st of June; that is, 44 days after the 
contamination. Tuberculin injected June 21st gave the follow¬ 
ing temperatures : 
6 A. M., 40; 9 A. M., 40; NOON, 39.7 ; 3 P. M., 39.5 ; 6 
p. m., 39*4* 
Animal No. 1 was tested eight times without giving a 
reaction. 
Cow No. 1 revealed all the organs and tissues normal with the 
exception of a large number of pisiform nodosities in the intes¬ 
tines of a parasital nature. 
Cow No. 2 .—The mouth, the velum of the palate, the 
pharynx, the larynx and the trachea have no noticeable lesion. 
The retropharyngeal glands on the right side are distended, 
hard and knotty and present on cutting a number of miliary 
yellowish caseic tubercles. The other pharyngeal glands and 
those of the throat region are normal. 
A careful examination of the intestinal mucosa shows a few 
Peyer’s glands thickened in places and suspected of tubercular 
infiltration ; in their vicinity the mesenteric glands show in 
their cortical layer a few miliary, yellowish and caseic tubercles- 
The right lung shows on its anterior lobe a nodule, yellowish, 
caseic, not softened nor calcified, the size of a large pea ; the 
bronchial glands normal.
