post that compares two of Anderson's Martian races. I remarked somewhere that, like ERB's green Martians, the Martians of the Technic History have social units called "hordes." However, I cannot find that post now so let me merely repeat the remark here.
That leaves only the Martians of The War Of Two Worlds, the most humanoid of Anderson's Martian races. Again, I am sure that I would have listed their physical characteristics in an earlier post but cannot easily find it so:
long straight legs;
lean waist and arms;
very broad chest and shoulders;
hairless brown skin;
long pointed ears;
small flat nose;
mobile, human-like mouth;
large slanted golden eyes;
An sf cliche? Sounding more like a man adapted to Mars than an independently evolved organism? Nevertheless, these particular Martians serve their purpose in this early novel.
