RABIES. 425 



founded on attempts to dissolve the mass, or to promote its 

 expulsion by pressure, or to extract it by operation. The 

 manner in which solution is to be accomplished, has been 

 described in the previous article. An attempt may be 

 made to force it out of the bladder through the urethra, 

 to which we should be more particularly led when we find 

 it already lodged within, or near to, the neck of the 

 organ. The left hand should be introduced into the rec- 

 tum, and be assisted by the right, in the line of the urethra : 

 if the stone be small, it may be brought forward, until a 

 forceps, introduced from the point of the penis, may reach 

 it. If it can be passed no farther than the curvature, it 

 must be cut down upon. When a larger stone is found 

 within the bladder, and the animal be a male, we must 

 proceed as detailed under lithotomy, among the operations. 

 In the female, the method of extracting the stone by litho- 

 tomy need not be practised. A dilitator is to be purchased 

 of the instrument makers ; this being introduced into the 

 short urethra of the mare, and afterwards expanded, enables 

 the calculus to be gi'asped with the forceps and with- 

 drawn.

ANIMAL, VEGETABLE, AND MINERAL POISONS. 

 RABIES. 



The rabid malady, or madness, is never spontaneous, but 

 always acquired from the application of the virus, by a 

 member of the canine or feline tribe. 



The symptoms of rabies in the horse are various ; it 

 usually, however, commences rather suddenly, by some 

 signs of uneasiness ; by sudden falling down, or break- 

 ing out into profuse sweats : in a few hours, however, the 

 animal becomes completely unruly : he stamps and paws 

 violently, and attempts to disengage himself from his halter. 

 Within twelve hours from the attack he is commonly fran- 

 tic : and we have seen one that levelled with the ground the 

 whole of the fittings of a six-stall stable, himself sweating,
