Previously published in 1941, this is an expanded, half new or completely rewritten, with the rest partly rewritten, and with newly added illustrations, story of zoological might-have-beens, some of which definitely existed. It is not a history of zoology, but an errant ambulation into the facts on the record, and off the record, concerning unicorns, giants, dragons, sea monsters, strange animals, puzzles, etc., etc., and proving that even today's science has no unanswerable solution to some of the manifestations. From the classics to the present day, he explores what has been told, in various versions, what is still being found out and what may be possible, and makes it thoroughly absorbing reading. Compendious in its research, and of extra-curricular appeal, this for the natural (and unnatural) history audience.
