CHRONIC COUGH. 235 



often relieves ; but these cases are safer in the hands of a com- 

 petent surgeon. Under no circumstances of this disease should 

 the animal be bled. 



Malignant or putrid sore throat, is fortunately but little 

 known in the United States, the author not being aware of 

 its existence in any portion. Cases presenting somewhat 

 similar symptoms have been found upon examination to differ 

 in a marked degree from those which accompany this form 

 of disease as they are laid down in the works of foreign 

 authors. A detailed description of this type of the disease is 

 therefore deemed unnecessary in the present treatise. 



CHRONIC COUGH. 



This arises from various causes, and is present in a number 

 of diseases. It is often symptomatic of some affection of the 

 lungs and air passages ; and it sometimes exists apparently as 

 an independent affection, the animal thriving well, and retain- - 

 ing uitimpaired his appetite and spirits. 



If it arises from irritation of the larynx, or upper part of 

 the throat, a few applications of mustard will be beneficial ; 

 if from worms in the stomach or intestines, treat as directed 

 under the head of " Worms." If it exists without any appar- 

 ent connection, or as the termination of disease previously 

 existing, give every night in a bran mash one of these pow- 

 ders : of sulphate of copper (blue vitriol), digitalis (fox-glove), 

 pulverized squills, nitre, and camphor, each one ounce ; to 

 be made into ten powders. Green food, as carrots, potatoes, 

 turnips, or parsnips, should be given when procurable.
