spayed while she gives suck, and the boar safely castrated at any 

 age. The operation of castrating is performed by cutting them 

 across the middle of each stone, then pull them gently out and 

 anoint the wound with tar. Spaying is performed by cutting in the 

 mid flank, on the left side, with a sharp knife or lancet, in order to 

 extirpate or cut off the parts destined for conception, and then stitch 

 up the wound, anoint the part with tar salve, keeping the animal 

 warm for two or three days. The usual way is to make the incision 

 in a sloping manner, two inches and a half long, that the fore finger 

 may be put in towards the back, to feel for the ovaries, which are 

 two kernels as big as acorns, one on each side of the uterus, one of 

 which being drawn towards the wound, the cord or string is cut, 

 and thus both taken out.
