cause of all the trouble is that injections of a solution of sulphuret 
of potash (potassic sulphuratum) one in twenty, repeated during 
the day, were sufficient to put a stop to the epileptiform symptoms 
of the dog I had under observation, and I have no doubt will 
rapidly put an end to the epizooty in question .—Gazette Medicate. 
UPON A SUPPOSED MEANS OF PRODUCING IMMUNITY AGAINST 
ANTHRAX. 
By M. Colin. 
The results of the experiments he has made prove : 
1st. That the viruleucy of the carbuncular blood dies out, or 
nearly so, between 55° and 57° Centigrade, for causes to be after¬ 
ward determined. 
2d. That in the cases where the blood warmed to that degree 
does not lose its properties, it produces anthrax with all its 
characteristics. 
3d. That the warmed blood, whose virulency is lost, has no 
nocivious action and acts like that of a healthy animal. 
4th. That this same blood, whose virulency has been destroyed 
by heat, does not insure immunity, for animals inoculated with 
it will afterwards take anthrax as easily as others, and die from 
it in the ordinary length of time, presenting all the characteristic 
lesions of the disease .—Bulletin of the Academy of Medicine. 
A CASE OF ACUTE PHTHISIS, PRODUCED BY DIRECT CONTAGION, 
IN A DOG. 
By Dr. H. Cullimore. 
About six years ago the author had a patient suffering with 
advanced pulmonary phthisis. This man, who coughed much, had 
profuse expectoration. A dog had the habit of licking and swal¬
