280 Diseases of Cattle. 



method of treatment has been discovered. It may be pre- 

 mised that all bleeding, purging, lowering medicines are hurt- 

 ful ; and that all local applications to " backen" the swellings 

 are useless. 



Prof. Williams believes the most promising treatment is : 



No. 311. Chlorate of potash, ^ oz. 



Water, 1 pint. 



Mix and give three times a day. 



This, he says, is superior to all other medicine. 



In blain, and whenever the disease arises from inoculation, 

 (as in "malignant pustule" in man), the great majority of 

 cases can be cured if seen at an early period, before the poi- 

 son of the local pustule or vesicle has been absorbed into the 

 system. The treatment must, however, be prompt. The 

 vesicle or pustule must be freely opened with a lancet or sharp 

 knife, from end to end, and the raw surface thus exposed 

 thoroughly mopped with a chloride of zinc solution (twenty 

 grains to the ounce of water), with tincture of the chloride 

 of iron, with sulphuric or nitric acid, nitrate of mercury or 

 of silver, or some other efficient caustic. The hot iron itself 

 is the best in some locations. 



In bloody murrain Youatt and others have spoken highly 

 of chloride of lime (bleaching powder) : — 



No. 312. Chloride of lime, 2 to 4 drachms. 



Prepared chalk, 1 oz. 



Laudanum, 2 drachms. 



Mix and give in a pint of warm gruel every two or three hours. 



A similar remedy has been praised by Sir J. Tyrrell, to- 

 wit: — 



No. 313. Sulphite of soda, 1 oz. 



Water, 3 gallons. 



Of this the sick animal is to be given to drink as much as it wants. 



Mr. Dun combines the soda with chlorate of potash, as : — 



No. 314. Sulphite of soda, 



Chlorate of potash, of each 1 oz. 



Give in a quart or two of water two or three times a day.
