NOCARD AND ROSSIGNOL. 
There was a temporary hyperthermy of 39°-5 June 15, due to 
the inoculation of tuberculin June 14. At 9 A. M. the 15th, the 
temperature had become normal aud it remained so until June 28, 
when it rose to 39A3 at 6.30 A. m., but at 9 A. M. it was 37 °. 8 . 
The indications are that the commencement of the infec¬ 
tion goes back to June 15, that is, the 38th day. 
Autopsy. 
Under the skin and on the internal wall of the trachea, where 
the needle of the syringe penetrated, there is found tumors, 
those under the skin larger than on the trachea. They have 
the appearance of pimples, infiltrated with yellowish and caseic 
clots. The mucous membrane of the trachea presents a patch 
of fine granulations. Some are half transpaient, others opaque 
and yellowish in the centre; nearly all are surrounded by a 
bright red halo. These granulations are disposed in linear se¬ 
ries ; more numerous above the point of inoculation and seen to 
stop short at the lower end of the larynx, the mucous mem¬ 
brane of which is normal. The mucous membrane of the large 
and small bronchii is sound. A thorough examination of the 
lung does not show any tubercular lesion to the eye or touch. 
The retro-pharyngeal glands are filled with a multitude of fine 
tubercular granulations, yellowish and caseic. The bronchial 
and oesophageal glands are involved, but the lesions are slight 
and apparently recent. 
It is a remarkable fact to see the bronchi and the lungs 
healthy after having so much infecting material injected into 
the trachea. 
Phagocytosis is so intense at the surface of the bronchial 
mucous membrane that the bacilli must have been eliminated 
with the expectorated mucus. The slight infection revealed 
by the autopsy, is manifestly caused by some traumatism by the 
inoculating needle. Without this traumatism it is probable 
that the cow would have escaped the infection.
