Martian Food (Biped)

Their undeniable preference for men as their source of nourishment is partly explained by the nature of the remains of the victims they had brought with them as provisions from Mars. These creatures, to judge from the shrivelled remains that have fallen into human hands, were bipeds with flimsy, silicious skeletons (almost like those of the silicious sponges) and feeble musculature, standing about six feet high and having round, erect heads, and large eyes in flinty sockets. Two or three of these seem to have been brought in each cylinder, and all were killed before earth was reached. It was just as well for them, for the mere attempt to stand upright upon our planet would have broken every bone in their bodies.
