should be under the eye of the professional practitioner. Stimulating 

 applications are required for dressing the sores, while a generous, 

 easily digestible diet is necessary, with tonic and alterative medicine. 

 Ulceration heals by granulations. (See Appendix.) 



31. Mortification, or death of a part, arises from a variety of 

 causes, independently of being one of the results of inflammation ; 

 such as a loss of nerve power, the plugging of a blood vessel, and the 

 want of blood in the part, &c. We have both moist and dry gangrene. 

 Gangrene is moist when the tissues undergo softening or liquifaction. 

 It is dry from obstruction of the circulation, when the parts contain 

 little fluid ; for example, senile gangrene in old people— affecting 

 the big toe. 



32. In Sloughs, mortification may be complete or partial. The 

 tissues may be involved to a greater ot lesser extent, when the morbid 

 process is arrested and a line of demarcation is then formed betwen the 

 living and dead structures ; the dead portion sloughing off, as is seen 

 in mares and cows when the passage has been damaged in difficult 

 parturition ; or the sloughing off of one or more quarters of the udder 

 in mares, cows, and sheep from extensive inflammation of the 

 mammary gland. 



33. When an extensive injury has been done to any portion of the 

 body, more particularly the thick muscular part of the hips and 

 quarters — being torn and lacerated by some foreign body, such as a 

 cart or a gig shaft — the neigbouring tissues are so much damaged 

 (the blood vessels being destroyed and nerve fibre shattered) that the 

 part is very liable to mortification, owing to the inflammation set up 

 being generally so intense. Our object, and greatest endeavour, 

 should be to keep the mflammation in check, and to give tone to the 

 neighbouring parts, and to assist them to throw off the damaged and 

 dead portions. The best treatment I have found is to plug or cover 

 the external wound with antiseptic dressings so as to exclude the air, 

 combined with a continuous application of blankets, 6 or 8 ply thick, 

 wrung out of cold water every four or five hours, or when they become
