It is true, however, that in spite of our splendid tissues we have to be more solidly built than the Terrestrials, whose limbs remind us unpleasantly of insects.

The woman on the rock would certainly have surprised you, for she is a member of one of our most recent generations, whose skin and flesh are darkly translucent. Seeing her there, with the sunlight drenching her limbs, you might have taken her for a statue, cut from some wine-dark alabaster, or from carbuncle; save that, with every movement of her arm, sunken gleams of crimson, topaz, and gold-brown rippled the inner night of her shoulder and flank. Her whole substance, within its lovely curves and planes, looked scarcely solid, but rather a volume of obscure flame and smoke poised on the rock. On her head a mass of hair, flame-like, smoke-like, was a reversion to the primitive in respect of which she could never decide whether it was a thing for shame or complacency. It was this pre-historic decoration which first drew me toward her. In a closer view you would have noticed that on her back and the outer sides of her limbs the skin's translucency was complicated by a very faint leopard-like mottling. I also bear that mottling; but I am of the sort whose flesh is opaque, and my bronze-green skin is of a texture somewhat harsher than I should choose. In her, how well I know it, the skin is soft and rich to the exploring hand.

While I watched her, she raised her face from studying the water-dwellers, and looked at me, laughing. It was that look which gave me the brief but strangely significant experience the memory of which was to refresh me so often in your uncouth world. It was not only that her face was lit up with merriment and tenderness; but in that fleeting expression the very spirit of humanity seemed to regard me. I cannot make you realize the potency of that glance, for the faces of your own kind afford almost no hint of such illumination. I can only assert that in our species, facial expression is more developed than in yours. The facial muscles respond to every changing flicker of experience and emotion, as pools respond to every breath of wind with a thousand criss-cross rippling tremors.

The face that now looked at me was unlike terrestrial countenances both in its subtly alien contours and in its dark translucency, which half-revealed the underlying paleness of bone. It was like a stirred and dancing pool of dark but warm-tinted wine, in which the sunlight revelled. But the eyes were bright jewels capable of many phases from sapphire to emerald.

Like others of our kind, this girl bore two additional bright eyes in the back of her head. They sparkled quaintly in the archaic glory of her hair. Like the rest of us, she had on her crown yet another and more important organ of vision which we call the astronomical eye. Normally sunken level with her hair, it could at will be projected upwards like a squat telescope. The exquisite development of this organ in her had determined her career. All of us are in a manner astronomers; but she is an astronomer by profession.

Her whole face, though so brilliantly alive, was unlike any human type known to readers of this book, since it was so much more animal. Her nose was broad and feline, but delicately moulded. Her full lips were subtle at the corners. Her ears moved among her locks like the ears of a lion.

Grotesque, you say, inhuman! No! Beside this the opaque and sluggish faces of your proudest beauties are little better than lumps of clay, or the masks of insects.

But indeed it is impossible for you to see her as I saw her then. For in that look there seemed to find expression the whole achievement of our race, and the full knowledge of its impending tragedy. At the same time there was in it a half-mischievous piety toward the little simple creatures that she had been watching, and equally, it seemed, toward the stars and man himself.

Smiling, she now spoke to me; if I may call 'speech' the telepathic influence which invaded my brain from hers.

That you may understand the significance of her words, I must explain that in our Neptunian rock-pools there are living things of three very different stocks. The first is rare. One may encounter in some sheltered cranny a vague greenish slime. This is the only relic of primeval Neptunian life, long since outclassed by invaders. The second stock is by far the commonest throughout our world. Nearly all our living types are triumphant descendants of the few animals and plants which men brought, deliberately or by accident, to Neptune from Venus, nearly a thousand million years before my day, and almost as long after the age that you call present.
