Tarzan and the Ant Men

I’ve read some of the Mars books, but I never got into Tarzan. And there are a lot of books in the series. Somehow I have to think ERB was paid by the character, not the word:

He is captured on the battle-ground and taken prisoner by the Veltopismakusians, whose scientist Zoanthrohago conducts an experiment reducing him to the size of a Minunian, and the ape-man is imprisoned and enslaved among other Trohanadalmakusian prisoners of war. He meets, though, Komodoflorensal in the dungeons of Veltopismakus, and together they are able to make a daring escape.
