THE HOG. 409 



cised in the same degree as dn the natural state, become less 

 developed, and the head becomes more prone : the back and 

 loins become more long, the body is rendered more capacious, 

 and the limbs become shorter and less muscular : and ana- 

 tomy shews that the stomach and intestinal canal have ex- 

 tended. With the enlargement of the trunk, the animals be- 

 come less suited for active motion, and, along with the form of 

 their bodies, their habits and instincts change. They are more 

 insatiate of food, and the tendency to obesity increases. They 

 become diurnal in their habits, and so do not choose the night 

 for their search of food. The male no longer seeks to dwell 

 secluded from his fellows, and the female brings forth her 

 young more frequently, and in greater numbers. With the 

 diminished strength and power of active motion, the desire 

 of liberty leaves them : they become content to grovel in the 

 sty, and to return to it after a few hours of freedom. The 

 creature that would have rushed on the armed horseman, and 

 laid prostrate the fiercest dogs, now flees from the swine- 

 herd's cur, and yields obedience to the voice of a child. Nay 

 more, they communicate their change of form, appetites, and 

 habits, to their progeny ; and a new race of creatures, in 

 truth, is formed, suited to a new condition. Nor is it certain 

 that the animals ever revert to their former state. At least, 

 when the domestication has continued for a long time, as_in the 

 case of the common Swine of Europe, the tendency to return 

 to the ancient type proceeds with a degree of slowness which 

 is imperceptible. Many of the Swine of South America carried 

 thither by the Spaniards have escaped into the woods, but 

 they have not become Wild Hogs, but remain in herds. In 

 the woods of Sweden and Norway, where pigs are allowed 

 to roam at large, they are troublesome, and even dangerous 

 to be met with, but they remain together, and are easy to be 

 distinguished from the parent race. In the North Highlands 

 of Scotland the pigs are left almost in the state of nature, 

 being suffered to graze on the hills like sheep, and to search 

 undisturbed for their food ; yet these creatures, although
