 ROT IN HORSES. 

 In tlie north of England, and, indeed, in many 

 other parts, the rot is made to express either inflam- 

 luation of the kuigs, or intestines, or liver, or of any 

 internal organ, because the gangrenous appearance 

 of these parts in these cases makes farriers con- 

 clude that their horses have long been rotten : but 

 improved farriery has now not only given more pro- 

 per terms to these diseases, but has taught us how to 

 distinguish them ixom each other, from whence has 

 spruijg a more active and judicious mode of treat- 

 ment. 



ROWELS. 



These, like blisters, act by inflaming the surface, 

 whereby more deep-seated inflammations are re- 

 moved. The mode of making a rowel is well known. 

 A slit being cut in the skin, about an inch in lengtli, 

 the finger is introduced to separate the surrounding 

 skin from the flesh, Szc, leaving, by this means, a 

 circle of the size of half-a-crown, into which is in- 

 troduced a piece of stiff leatiier of the same size, 

 smeared over with blistering ointment, or yellow basi- 

 licon. The sooner the inflammation is wished to be 

 raised, the more active is the substance we chuse to 

 put on the leather ; hence, in rising of the lights, in 

 red chulic, staggers, &c., when we use rowels, it is 

 proper to smear the leather with blistering ointment. 

 Rowels are of great service as a drain in farcy, 

 swelled legs, inflammation of the eyes, grease, &c. 

 &c. The parts they are usually placed in are, under 

 the throat, between the fore legs, along the belly, 

 and within side the thighs.
