away with decided advantage : but when it is necessary 

 to repeat the bleeding, the degree of fever and the strength 

 of the beast will regulate the quantity. The blood should 

 flow from a large orifice, for sudden depletion is far more 

 powerful in its operation than when the blood is suffered 

 slowly to trickle down. The blood must never be suffered 

 to fall upon the ground, but should be received in a measure, 

 in order that the quantity taken may be known. No ab- 

 solute quantity of blood should ever be prescribed, but 

 when extensive bleeding is demanded, the stream should 

 flow until the pulse falters, or intermits, or the animal be- 

 gins to heave violently, or threatens to fall, or other cir- 

 cumstances show that the system is sufficiently affected. 

 The beast should not be permitted to drink cold water 

 immediately after bleeding, nor to graze in the field : the 

 former has sometimes induced troublesome catarrh, and 

 the latter may cause the orifice to open again. If this 

 operation is performed in the summer season, it will be 

 most prudent to fetch the cattle out of the pasture toward 

 evening, in order that they may be bled ; and after that, 

 to let them stand in the fold-yard all night, and drive them 

 back to the field on the following morning. 



PHYSICKING, 



Is useful, 1st, soon after a cow calves, to prevent the 

 milk fever. 



2nd. When cattle have eaten too greedily of clover, 

 or other rich food, they become dull and lose their ap- 

 petite. A slight purge will generally relieve them. 



3rd. When cattle become bound in their body. Give 

 a purging drink immediately, and repeat every twelve 

 hours. A clyster will be useful, if the purge does not 

 answer. 



4th. It is proper to purge in cases of " red-water."
