A he plexiform ganglions are entirely healthy. Dog No. j .— 
2 days of incubation ; killed twelve hours after appearance of 
aralysis. Superb ganglionary lesions; half of the cells are 
estroyed ; the whole ganglion is infiltrated with leucocytes, 
besides those we have examined the plexiform ganglions of a 
hep herd dog killed during an access of raving madness in 
diich he had bitten several dogs and sheep. The ganglion- 
ry lesions were insignificant: a little pericapsular infiltra- 
lOU here and there ; it would be impossible by the single ex- 
mination of the sections, to tell that the dog was rabid. Yet 
le diagnosis is clinically certain and inoculation of the bulb 
ave rabies to the inoculated rabbits. From these researches, 
1 . Nocard concludes that the histological remains like the 
ecroscopical diagnosis. When the result is positive, which is 
le rule, in both cases, when the dog dies by the natural evolu- 
ons of the disease, one may affirm that the dog was rabid ; 
ut when the result is negative, which is frequent, when the 
og is killed immediately after he has bitten, one cannot affirm 
lat the dog was not rabid ; the diagnosis remains uncertain, 
;tid the strict duty of the veterinarian is still to advise those 
lat are bitten to resort to Pasteur treatment. 
Earyngeae Tumor in a Cow [By M. Mathis].— This 
limal, about 12 years of age, had been abandoned by the 
wner as being in a state of advanced tuberculosis. She was 
1 'iffering with loud roaring, much marked in inspiration, and 
uite weak in expiration ; her respiration was now and then 
:celerated, percussion of the chest gave an exaggerated reso- 
ance all over the lungs; auscultation of the trachea and 
.rynx justified the localization of the roaring at the larynx ; in 
stening to the chest nothing could be heard, no roaring nor 
ven the respiratory murmur. With these exceptions the ani¬ 
mal is in most satisfactory condition. The diagnosis of tubercu- 
•sis was discarded for want of symptoms and by the use of tu- 
Trculin ; and that of laryngeal trouble, made out by tracheo- 
>my, which had to be performed for fear of asphyxia, was con- 
:med, when previous to being killed the larynx was opened 
; for the operation of arytenectomy and a tumor was discovered 
i the right vocal cord, of non-tubercular nature, the size of a 
peon’s egg, closing almost entirely the glottic opening, formed 
‘ whitish fibroid tissue.— (Jour, de Med. Vet. and Zootechnie.)
