small, as to be of no advantage; or it may be so 

 considerable as to produce fainting, before the ope- 

 rator thinks of stopping the orifice. 



For the purpose of measuring the quantity of 

 blood taken away, Mr. White recommends a gradu- 

 ated tin vessel, capable of containing five quarts; 

 every pint being marked on the inside of the vessel, 

 so that the quantity of blood that is taken off may 

 be exactly known. The blood should always be pre- 

 served, that we may judge from its appearance of 

 the nature of the disease, and whether it is proper 

 or not to repeat the operation. If the blood conti- 

 nues fluid for a considerable time, it shov/s that 

 there is an inflammatory state of the body ; and if a 

 jelly-like substance, of a whitish or light buff colour, 

 and rather firm consistence, appears on the surface 

 after the blood has cooled, and especially if the sur-^ 

 face is hollowed, we may be certain that the animal's 

 complaint is of an inflammatory nature, that the| 

 bleeding has been proper, and must be repeated if 

 the symptoms continue or increase ; but if the blood 

 coagulates quickly, is uniformly of a dark liver 

 colour, loose, and easily broken, with a considerable 

 quantity of water upon its surface, it denotes debi- 

 lity, and shews that the disease arises from a weak- . 

 ness of the system ; that instead of hleeding, toni 

 and cordial medicines are to be employed, witl 

 every thing that may tend to restore the animal'i 

 strength. 



When a sufficient quantity of blood has beei 

 taken away, it is for the most part necessary to si 

 cure the orifice, in order to prevent future accident^ 

 bleeding. This is usually done by thrusting a com- 

 mon pin through the lips of the wound, and twining; 

 about it a little horse hair. As in this way the 

 wound often rankles, and becomes a sore difficult to 

 heal, which we are disposed to attribute to the brass 

 pin employed, as often as to any other cause ; we 

 would recommend a pin of silver, or at least of po-
