that its progress may not be impeded by them. A ligature should 

 be first passed round the neck, and a hand held over the eye, unless 

 the operator be very expert, when the use of the fingers will dispense 

 with the ligature. The quantity of blood taken is usually too small. 

 In inflammatory diseases, a large horse, particularly in the early 

 stage of a complaint, will bear to lose eight or ten quarts : and half 

 the quantity may be taken away two or three times afterwards, if 

 the violence of the symptoms seem to require it; and the blood 

 should be drawn in a large stream to do all the good it is capable of. 

 After the bleeding is finished introduce a sharp pin, and avoid 

 drawing the skin away from the vein while pinning, which lets the 

 blood escape between the vein and skin ; wrap round a piece of tow 

 or hemp, and next day remove the pin, which might otherwise 

 inflame the neck. In drawing blood let it always be measured ; 

 letting it fall on the ground prevents the ascertaining the quantity ; 

 it also prevents any observation on the state of the blood ; which if 

 it form itself into a cup-like cavity on its surface, and exhibit a 

 tough yellow crust over this cavity it betokens an inflammatory 

 state of blood that will require further bleedings, unless the weak- 

 ness forbid. After the bleeding, it now and then happens from 

 rusty lancets, too violent a stroke with the blood stick, or from 

 drawing away the skin too much, while pinning up, that the orifice 

 inflames and hardens, and ichor is seen to ooze out between its 

 edges. Immediately after this is discovered, recourse must be had 

 to an able veterinary surgeon, or the horse will lose the vein, and 

 perhaps his life.

127. The foWow'mg formuIcB for veterinary practice 

 have been compiled from the works of the most eminent 

 veterinary writers of the present day, as Blaine, Clark, 

 Laurence, Peel, White, &c. ; and we can from our 

 own experience also, confidently recommend the selec- 

 tion to the notice of agriculturists, and the owners 

 of horses in general. It would be prudent for such as 

 have many horses, and particularly for such as live at 

 a distance from the assistance of an able veterinarian, 

 to keep the more necessary articles by them in case 

 of emergence : some venders of horse drugs keep
