Carbuncle of the Coronary Band. — This consists 

 of an oval, irregular swelling on some portion of 

 the coronary band. It is hard at first and some- 

 times very painful, causing lameness. After a 

 time suppuration takes place at several points, 

 which discharges unhealthy matter. In some 

 cases it will spread all around the coronary, and 

 there will be a number of small openings, from 

 which thin matter will exude, forming a very un- 

 healthy looking sore. Prof. Williams, of Edin- 

 burgh, says: "I am inclined to think it is due to a 

 blood poison similar to that of glanders and farcy, 

 as it is oftenest seen in unhealthy situations, ill- 

 ventilated stables, and in horses with bad or gross 

 constitutions. I was inclined, when I first saw it, 

 to attribute it to some injury to the part, and to 

 believe that the unhealthy action was the conse- 

 quence of such an injury, or to the introduction of 

 some deleterious material into the wound; but 

 further experience has convinced me that it often 

 originates from constitutional causes, and that it 

 is an inflammation of the coronary substance, 

 due to the presence of some morbid material in 

 the blood." I am inclined to believe that the opin- 

 ion of Prof. Williams is correct, as it is a very dif- 

 ficult derangement to cure. 



Treatment: Poultice for a few days at first to 

 assist it to form matter, then apply a lotion of 

 acetate of lead half an ounce, sulphate of zinc half
