First off I have to say that this book was not one of Burroughs' best, in my opinion. There were some very clumsy scenes and way too much in the way of coincidence. And the scene where the humans killed some of the reptilians, skinned them, and wore the skins to escape was ludicrous to the point where I was ready to roll on the floor in laughter. And I know that the world of Pelucidar is no longer possible to modern minds. Still, the novel was entertaining and all such old science fiction classics are. And well worth the look and the read by anyone who loved Tarzan or John Carter.
