138 The Horse Farrier. 



A plethoric horse should be half starved. If the throat 

 is sore, rub it with warm vinegar and salt, or blister ; 

 steam the nostrils, to encourage the discharge ; walk the 

 horse a little, for exercise ; administer the following : 

 Oil of Croton, five drops ; Nitrate of potassa, 4 to 6 

 drachms ; Potassio-tartrate of antimony, 1 drachm ; spir- 

 it of nitric ether, 4 drachms to 1 ounce ; solution of 

 acetate of ammonia, 2 to 4 ounces ; warm water suf- 

 ficient to make a draught. 



Sometimes four drachms of bi-tartrate of potassa may 

 he added to the above ; and, when the head appeared 

 much aflJected, a drachm of camj^hor. This draught may 

 generally be administered once, but sometimes twice a 

 day, the croton oil being omitted after the first dose : 

 after the first day, two drachms of powdered gentian may 

 be added ; and after the second or third day, a ball may 

 be substituted for the draught, consisting of : nitrate of 

 potassa, 3 drachms ; potassio-tartrate of antimony, 1 

 drachm ; powdered gentian root, 2 drachms ; powdered 

 pimento berries, 1 drachm ; treacle sufiicient to form a 

 ball. 



SPASMS OF THE LARYNX AXD LARYNGITIS. 



The larynx is an ii-regular cartilaginous tube, forming the 

 upper extremity of the wuid pipe, and is the organ 

 which produces that peculiar sound called neighing. It 

 affords free passage in its normal state for respiration, 

 and also attachment for numerous muscles. Its internal 

 cavities are protected by the common membrane termed 

 tnucous^ which at times become the seat of a disease 

 known as laryngitis. 



The disease appears to be analogous to croup (in the 

 human family.) Spasm of the larynx may result from a 

 mucous affection, induced by mdigestion. 



Symtoms of Spasm of the Larnyx. — Sometimes the 

 disease manifests itself in a moment, as it were, with a 

 most terrible severity ; the animal begins to gasp for
