DISEASES AND REMEDIES. 451 



After this, the following purgative drink may be given with 

 considerable advantage : 



Carbonate of potash, . . . . . .2 drachms, 



Sulphate of soda, ...... 6 ounces, 



Barbadoes tar, . . . . . . .3 drachms, 



Warm water, ....... 1 pint. 



Mix for one dose. 



This dose will generally suffice for an animal of two years of 

 age. Should there be any difficulty in procuring these medicines, 

 give from four to six ounces of common salt in a pint of water; 

 the addition of four ounces of castor oil, or even linseed oil, 

 will render it more efficacious. As this disease frequently proves 

 fatal, in whatever manner it is treated, preventive measures should 

 be speedily applied. Should the animal, however, be relieved 

 by the treatment above described, it may occasion considerable 

 weakness: and consequently the following may be given twice 

 a day: 



Ginger, ......... 2 drachms. 



Powdered caraway seeds, ..... 1 ounce. 



To be given in a pint of oatmeal gruel, or ale.

 with the following liniment : 



Spirit of sal-ammoniac, . . . . . .1 ounce, 



Linseed oil, ....... 4 ounces, 



Oil of turpentine, . . . . . . .2 ounces. 



Mix. 



Setons in the dewlap, or other parts of the body, are occasion-

 duced by feeding cattle too hastily, Mr. Lawrence has very 

 judiciously advised that a short, or inferior keep should be 

 reserved, as a digesting place, where cattle may occasionally be 

 turned, to empty and exercise themselves. This is certainly pre- 

 ferable to bleeding, or any medical preventive. 



BLOODY MURRAIN, RED WATER AND BLACK WATER. 



Causes. The red water and black water arise from a preter- 

 natural quantity of blood being determined to the kidneys, and 

 a consequent rupture of some of the minute blood vessels of 

 those organs. This undue determination of blood to the kidneys 

 is very frequently induced by turning cattle, in the spring of the 

 year, into low pasture grounds, or woodland pastures, where the 

 air is moist, and lessens perspiration, occasioning the blood to
