Mercury, indeed, supplies a step of decided departure towards Vulcan; but having this time given Mercury the slip, we plunged at once into Vulcanian peculiarities. The whole of the little planet looks like a lump of metal, and the leaden hue throughout has at first a non-natural and depressing effect. But this soon wears off as we get accustomed to the people, their gentle and pleasant ways, and their remarkably intelligent faces, in spite of their somewhat planetoid contour of figure. Certain metals enter largely into the organic physique, and give a curious aspect alike to animal and plant substance. The atmosphere is partly composed of metallic vapours, and there are small lakes or seas which supply those vapours, especially during the heat of the day, and between which and the atmosphere there is constant interchange.
