24S' THICK WIND. 



fully clear, bright yellow fluid. In sub-acute cases there is 

 considerable lymph floating in it, thus rendering it turbid. The 

 quantity varies in different cases, from a quart or two to several 

 gallons. 



In this disease the animal stands with legs straddling ; the 

 breathing is short and quick, and as the water accumulates the 

 respiration becomes more labored ; pulse small and quick ; stag- 

 gering gait; breast, belly, and sheath swelled, leaving after 

 pressure the impression of the fingers; if the ear is applied to 

 the side, no sounds are heard. 



No course of treatment can be suggested which would be 

 likely to succeed in the hands of the amateur; this disease far 

 too oflen proving fatal in the most skillful hands. 



THICK WIND. 

 This disease differs in its action and effects from broken wind 

 or heaves, though they are frequently confounded. It is cha- 

 racterized by a quickened respiration, in consequence of the 

 obstruction existing in the air passages as the termination of 

 inflammatory action. The capacity of the lungs is often very 

 considerably diminished ; the air-cells become filled up or obli- 

 terated ; and the bronchial tubes become thickened ; so that the 

 same amount of atmospheric air cannot be admitted, thus giving 

 rise to the quick, blowing action witnessed in this disease. "It 

 is astonishing," says Mr. Spooner, "what great alteration of 

 the structure of the lungs may exist, and the horse be still able 

 to perform his accustomed work. I remember a horse that foi 

 some months worked in a fast coach, doing a stage of twelve 

 miles daily in about an hour and a quarter. He was seized 

 with inflammation of the lungs, and died in about sixteen hours.
