“Yes,” he said, “in respect to their warlike instincts, but not as to their forms. They are not human nor even vertebrate, but they are built on the radiate plan. In short they are almost exactly like your star fishes, but enormously bigger. I have seen them as large as twelve feet across, though their more common size at maturity is six to eight feet. The difference between the two races is that in one there are six spokes or limbs radiating from the central body and in the other there are but five. These limbs may be called either legs or arms, for they serve as either and are sometimes one and sometimes the other. There is a fleshy disc that forms the extremity of each limb, around which like the petals of a flower are the fingers or toes, about like so many thumbs. There are six of these in the six legged race and five in the five legged. This disc with its thumbs forms the foot when the individual walks on land. Two of them are always on the ground when he is standing, while the other four are free to be used as hands, these thumbs being opposable and able to grasp tolerably well. “When they move on land it is always in an upright position, and they roll along edgewise like a wheel destitute of felloes rolling on the ends of the spokes. The central piece or hub constitutes the body including the stomach, heart, lungs etc., as well as the sense organs, and brain. The shape of the body is like a short stout cylinder tapering to a rounded point at each end from one and a half to two feet in diameter, the legs radiating from the sides. At the center of one end of this body is the mouth, and the brain is located all round it in what we would call the cheeks. There is no neck. There are six eyes immediately around the mouth corresponding with the six legs, and just outside of the eyes are six ear holes with closable lips, but no outside flaps or shells. Outside of these are six breathing or blow holes leading into the lungs. The mouth is round and the lips pucker together when closing. There is no up or down to the Martian man, he stands equally well on any pair of his legs and handles equally well with any of his hands, and this is one of his greatest drawbacks. He has a thick horny skin which appears to have been the only skeleton possessed by his ancestors, but in addition, he has a light internal skeleton developed later by the practice of standing and running on his limbs, which consists of a lot of plates and hoop like ribs in the body, and what would pass for thigh and leg bones in each limb. These last are hung with ball and socket joints both at the articulation with the body and at the elbow and wrist. The limbs are thus remarkably supple and when the Martian has a mind to, he can walk extremely well sideways on two legs, that is, the head or mouth going forward. And this is the way he should walk as our people long ago pointed out to the Martians. He can walk on the same two feet
