 be left entirely free, as it is a most effective agent in carry- 

 ing fluids onwards to the gullet, and its action greatly 

 facilitates the operation of drenching.

 altered conditions of the blood, probably also to heredi- 

 tary taint, which primarily may originate in the same 

 causes. 



Plethora, or fulness of blood, is known to consist of 

 an excess of nutritious elements, which circulating 

 throughout the tissues give rise to rapidity of growth, 

 and improvement recognised as "blooming condition. " 

 When these appearances attract attention by rapid and 

 unusual development, a change in the mode of feeding is 

 urgently called for, particularly for animals taking little 

 or no exercise. Such should also be purged, and those 

 feeding on over-luxurious pastures must be removed to 

 another where they may work for their living. Administer
