The surface which reflects heat most readily, suffers it to escape but slowly by radiation. Reflection takes place most readily in objects of a white colour, and from such, consequently, heat will radiate with difficulty. If we suppose two animals, the one of a black colour, and the other white, placed in a higher temperature than that of their own body, the heat will enter the one that is black with the greatest rapidity, and elevate its temperature considerably above the other. These differences are observable in wearing black and light coloured clothes during a hot day. When, on the other hand, these animals are placed in a situation, the temperature of which is consider thological Dictionary, article Common Gull, says, --" We have had this species alive for some years, and observed, that when it had attained its full mature plumage, in the second year, the head and neck is pure white during the summer; but, like the herring gull, these parts become streaked, and spotted with brown, in autumn, which is continued all the winter; and in the spring become again pure white."
