Treat mtnf ma}' consist in the internal use of tonics (sulphate of iron, 

 3 drams, dail\') and the washing out of the womb, as described under 

 the last heading, followed b}' an astringent antiseptic injection (car- 

 bolic acid 2 teaspoonfuls, tannic acid one-half dram, water 1 quart). 

 This may be repeated two or three times a day. 



LAMINITIS, OR I OUNDER, FOLLOWIXG TARTUKITIOX. 



This sometimes follows on inflammation of the womb, as it frequently 

 does on disorder of the stomach. Its sj^nptoms agree Mith those of the 

 common form of founder, and treatment need not differ. 



DISEASES OF THE UDDER AND TEATS. 



CONGESTION AND INFLAMMATIOX OF THK IDDER. 



This is comparatively rare in the mare, though in some cases the 

 udder becomes painfully engorged before parturition, and a doughy 

 swelling, pitting on pressure, extends forward on the lower surface of 

 tlie abdomen. When this goes on to active inflammation one or ))oth 

 of the glands become enlarged, hot, tense, and painful; the milk is 

 dried up or replaced hy a watery or reddish serous fluid, which at 

 times becomes fetid; the animal walks lame, loses appetite, and shows 

 general disorder and fever. The condition may end in recoverv, in 

 abscess, induration, or gangrene, and in some cases may lay the foun- 

 dation for a tumor of the gland, 



Trentnient. — The treatment is simple so long as there is only conges- 

 tion. Active rubbing with lard or oil, or, better, camphorated oil, 

 and the frequent drawing ofl: of the milk, by the foal or with the hand, 

 will usually bring about a rapid improvement. When active inflam- 

 mation is pi-esent fomentation with w^arm water may ])e kept up for 

 an hour and followed by the application of the camphorated oil, to 

 which has been added some carbonate of soda and extract of bella- 

 donna, A dose of laxative medicine (4 drams Barbados aloes) will 

 be of service in reducing fever, and one-half ounce saltpeter daily will 

 serve a similar end. In case the milk coagulates in the udder and can 

 not be withdrawn, or when the liquid becomes fetid, a solution of 20 

 grains carbonate of soda and 10 drops carbolic acid dissolved in an 

 ounce of water should be injected into the teat. In doing this it must 

 be noted that the mare has three separate ducts opening on the summit 

 of each teat and each must be caref ull}^ injected. To draw off the 

 fetid product it may be needful to use a suiall milking tube, or spring 

 teat dilator designed by the writer (Plate VIII, figs. 2 aud 3). When 

 'pus forms and points externally, and can not find a free escape b}' the 

 teat, the spot where it fluctuates must be opened freely with the knife
