partition between the inferior maxillary sinus and the nostril 
was absorbed, clearly showing that at one time the growth had 
been attached to the fang. The crown of the molar was per¬ 
fectly normal. On making a section of the mass it appeared to 
be composed of material resembling crusta petrosa. 
John Tomes, in Dental Physiology and Surgery, says: 
“ Dental exostosis is caused by irritation of the periosteum, due 
in a great majority of cases to caries, and arises from the crusta 
petrosa.”

CONTAGIOUS PLEURO-PNEUMONIA OF GOATS. 
By Me. Duquesnoy. 
Two sickly female goats were introduced amongst the 
animals of a flock whose milk was sold in the streets of a city of 
Southern France. A few days later four of these goats had died, 
and all the animals were more or less sickly. They ate less, gave 
less milk, coughed, and had a discharge from the nose. 
Two of the worst cases presented the following symptoms; 
Great emaciation ; skin dry and warm ; eyes sunken and running; 
conjunctiva injected ; a discharge from the nose, abundant and 
gummy; mouth warm and congested ; breath offensive; respira¬ 
tion difficult and painful; cough frequent and deep ; pressure on 
the chest and percussion painful and dull; pulse 120 ; lactation 
and rumination suppressed; diarrhoea foetid and greenish; tem¬ 
perature 103°. 
Post-Mortem .—Intestinal tract about normal; both lungs hep- 
atized; in the right pleural sac, effusion and pleural adhesions; 
on the left, adhesions only ; sections of the lungs show a mar¬ 
bled appearance, of various colors, forming spots of a reddish and 
brownish aspect, separated by infiltrated and hypertrophied inter¬ 
lobular connective tissue; the pericardium congested, with some 
ecchymotic spots on the cardiac serous membranes. 
From the symptoms and the lesions, the author concludes up¬ 
on a diagnosis of contagious pleuro-pneumonia.— Journal de 
Zootechnie.
