The Natural History of Selborne

Dr Chandler’s Bantam sow brought him this last summer a large litter of pigs, several of which were not cloven-footed, but had their toes joined together.  For tho’ on the upper part of the foot there was somewhat of a suture, or division; yet below in the soles the toes were perfectly united; and on some of the hind legs there was a solid hoof like that of a colt.  The feet of the sow are completely cloven.  Mr Ray in his Synopsis animalium quadrupedum, takes on notice of this singular variety; but Linnaeus in his Systema Naturae says, “Varietas frequens Upsaliae Suis domestici semper monunguli: in ceteris eadem species.”
