Colour and constitutional peculiarities go together, of which many remarkable cases could be given amongst animals and plants. From
the

facts collected by Heusinger, it appears that white sheep and pigs are injured by certain plants, whilst dark-coloured individuals escape: Professor Wyman has recently communicated to me a good illustration of this fact; on asking some farmers in
Virginia
Florida
how it was that all their pigs were black, they informed him that the pigs ate the paint-root (Lachnanthes), which coloured their bones pink, and which caused the hoofs of all but the black varieties to drop off; and one of the "crackers" ( I. e.
Virginia
Florida
squatters) added, "we select the black members of a litter for raising, as they alone have a good chance of living." Hairless dogs have imperfect
