6. In the yellows it is generally necessary to give a purging drink, 

 and, after that, cordial tonic drinks, in order to invigorate the digestive 

 organs. 



7. When medicines are given to prevent cows from slipping theii 

 calves, they are generally preceded by physic. 



8. In all inflammatory complaints, a purging drink should be ad

9. If external inflammation, occasioned by wounds, bruises, and 

 other causes, runs high, and aflfects the whole system, purgative 

 medicines are absolutely necessary. 



CHAPTER IV. 



ON SETONING. 



The utility of setoning for the cure of several diseases incident to 

 neat cattle cannot be doubted. There are many localities in which, 

 if farmers did not adopt this precaution, they would lose great num- 

 bers of their young from tiie black leg. 



In some districts the hoose in calves is very prevalent and fatal ; 

 where this is the case, they should all be setoned when they are 

 getting into condition, and before they are attacked by the disease. 

 This will either lessen the violence of the complaint or prevent it 

 altogether. 



In joint evil, I have frequently inserted a seton in the dewlap with 

 decided gfood eflect. 



Setoning will be often prescribed, in the course of this treatise, in 

 inflammatory complaints ; and it acts by exciting a new and artificial 

 inflammation in the neighbourhood of the former one, and thus lessen- 

 iwg its intensity. This plainly proceeds on the principle of divertincj 

 to another part a portion of the blood which was determined lo the 

 oricrinal one, while also a new direction is given to a portion of the 

 nervous influence or power which was concentrated on it. This is in 

 accordance with the generally received medical maxim, that no two 

 violent inflammations, of different character, can exist in neighbour- 

 ing parts at the same time; and that in proportion to the intensity of 

 the one the other will be diminished. 



By the discharge which a seton produces it will liliewise relvev« 

 the overloaded vessels of a neighbouring inflamed part.
