lislied steel. The pin need not pass through more 

 than the skin ; anci in some cases, wlien the horse 

 can conveniently be fastened to the rack after bleed- 

 ing, the pin may be entirely dispensed with. 



As it is often required to bleed on either side of 

 the neck, or on both sides, it is proper that the ope- 

 rator should be able to bleed with either hand. This 

 is indeed not quite so necessary in bleeding horses 

 and cattle as in the human subject ; but it will be 

 often found very convenient in both. 



In some cases, especially in inflammation of the 

 brain, where a sudden and copious loss of blood is 

 required, it becomes necessary to open the temporal 

 artery. This is easily effected, as the artery is si- 

 tuated very superficially, about an inch and a half 

 backwards from the upper and outer corner of the 

 eye. It is most conveniently opened with a lancet, 

 and when a sufficient quantity of blood has been 

 drawn, the flow is in general very easily stopped by 

 making continued pressure upon the artery ; or, if 

 tliis should not succeed, and a dangerous effusion of 

 blood should be apprehended, this may be effectually 

 prevented by completely dividing the artery. 



INIr. Coleman, speaking of the inflammation of the 

 vein which sometimes succeeds bleeding, observes, 

 that * whenever inflammation attacks the internal 

 surface of veins from bleeding, or any wound, the 

 disease is to be considered as of the same nature, and 

 requiring the same remedies, as the exposure of 

 joints, or other cavities. 



' The first symptom of inflammation and suppura- 

 tion Avithin a vein, is generally a small degree of 

 swelling about the orifice, the lips of which soon 

 recede from each other, and a little oozing escapes 

 from the part. 



' At other times, the swelling will be more consi- 

 derable, attended with frequent hoemorrhage ; and 

 iwhere the swelling extends much above the orifice,
