clothing. If the atmosphere of the stable be raised to a 

 temperature greatly exceeding that of the open air, the 

 horses, when taken out to exercise or work, are liable to 

 serious consequences, from the great increase in the amount 

 of oxygen which rushes through the respiratory organs in 

 the act of inspiration. The quantity of oxygen is regulated 

 by the temperature of the atmosphere; and there are few per- 

 sons who have not experienced the inconvenience attendant 

 upon passing from an over-heated ball-room into the open 

 air; and they generally take the precaution of adopting 

 additional clothing. The case of the horse is precisely 

 analogous. 



Although a very Liberal premium has been offered, the 

 cure for roaring has not yet been discovered. "When it pro- 

 ceeds from malformation, it is impossible : or if the cartilages 

 of the windpipe became ossified, no remedy can be found to 

 reach those parts. An extensive deposit of lymph having 

 taken place in the mucous membranes with which the re- 

 spiratory organs are defended, comes within the same cate- 

 gory. A strong stimulus applied to the sinews, joints, or 

 muscles, in the event of lameness, may, and frequently does, 

 impart a wonderful effect; but it is a different affair when in- 

 ternal organs, such as those of respiration, are disordered; 

 those parts cannot be brought into immediate contact with 

 any application. When a horse is affected with inflamma- 

 tion about those parts which are the seat of the disorder, if 

 it be vigorously attacked in its incipient state with the usual 

 stimulating preparations, providing there is no malformation 

 to contend against, the malady may in very many cases be 

 prevented; and a vast number of cases of confirmed roaring 

 are to be attributed to neglect or delay at the important crisis 

 of commencement. Those who would avoid breeding roarers 

 must avoid breeding from parents whose progeny has evinced 

 a predisposition to the complaint. So far every breeder has 

 the remedy in his own hand; but with the utmost caution, 

 all living creatures are subject to disorders; and if the results 

 are unfortunate, in defiance of the most skillful treatment, 

 breeders must console themselves with the reflection that 

 their disappointments are the decrees of fate. 



NOTE. 



A judicious selection of the most eligible parents for the 

 purpose of breeding, combined with careful attention to the 

 method of rearing and treatment of the offspring, will not
