326. It should be observed that his account does not apply to truly feral
pigs; but to pigs long introduced into the country and living in a half-
wild state. For the truly feral pigs of Jamaica see Gosse 'Sojourn in
Jamaica' 1851 page 386; and Col Hamilton Smith in 'Nat. Library' volume 9
page 93. With respect to Africa see Livingstone 'Expedition to the Zambesi'
1865 page 153. The most precise statement with respect to the tusks of the
West Indian feral boars is by P. Labat quoted by Roulin; but this author
attributes the state of these pigs to descent from a domestic stock which
he saw in Spain. Admiral Sulivan, R.N., had ample opportunities of
observing the wild pigs on Eagle Islet in the Falklands; and he informs me
that they resembled wild boars with bristly ridged backs and large tusks.
The pigs which have run wild in the province of Buenos Ayres (Rengger
'Saugethiere' s. 331) have not reverted to the wild type. De Blainville
'Osteographie' page 132 refers to two skulls of domestic pigs sent from
Patagonia by Al. d'Orbigny, and he states that they have the occipital
elevation of the wild European boar, but that the head altogether is "plus
courte et plus ramassee." He refers also to the skin of a feral pig from
North America, and says "il ressemble tout a fait a un petit sanglier, mais
il est presque tout noir, et peut-etre un peu plus ramasse dans ses
formes."

The common belief that all domesticated animals, when they run wild, revert
completely to the character of their parent-stock, is chiefly founded, as
far as I can discover, on feral pigs. But even in this case the belief is
not grounded on sufficient evidence; for the two main types, namely, S.
scrofa and indicus, have not been distinguished. The young, as we have just
seen, reacquire their longitudinal stripes, and the boars invariably
reassume their tusks. They revert also in the general shape of their
bodies, and in the length of their legs and muzzles, to the state of the
