Medium--I shall do my best, and where I fail you will prompt me. This animal reminds me of a horse, but it is larger than any horse I ever have seen. Its head is well proportioned to the size of its body and is as delicately formed as the head of a deer. Its ears are erect, pointed, rather small and set closely to its head. Its eyes are large, gentle and beautiful. Its neck is rather short, but symmetrical, and fringed with a long, silken mane. Its legs are well proportioned and its hoofs are daintily formed and semi-transparent. Its tail, almost sweeping the ground, is covered with long hair the color of its mane, which is a very dark brown, and its body is clothed with hair of a lighter shade of brown, rather, I should say, with shades of brown and white arranged in spots, like those of a leopard. I think it a very handsome animal. Is my description at all accurate? De L'Ester--Quite so; and this animal is a Lûm[a:], and the other is a Vetson. As I already have intimated on this Planet there are in its animal kingdom forms bearing striking resemblances to some existing on Earth, but owing to Planetary conditions they are of a larger type than their kindred of our Planet. You are to remember _that all life germs are homogeneous_, their varying expressions being the result of varying conditions. Thus throughout the myriad life expressions of different Planets there are endless strong resemblances. Why not? The conditions of the several Planets of our Solar System are not so utterly dissimilar as some of your learned persons declare them to be. And mark what I shall say: On Earth's physical plane there are at this time re-embodied ones whose inherent qualities will within the next half-century enable them to give to Earth's peoples undreamed of facts concerning other Worlds. Facts which will necessitate a _readjustment of accepted scientific conclusions_. Yes, necessarily, resemblances between the fauna and flora of Mars and Earth are closer than between those of any other two Planets of our Solar System. I say necessarily, for the reason that like produces like, and the conditions of Mars and Earth, being more nearly similar than are the corresponding conditions of any of their Planetary kindred, it follows that their productions must keep pace with conditions.
