This is a rare and highly collectable book. Copies in the original limited edition sell at auction in the thousands of pounds.
Reproductions are available and even these are quite pricey. You are getting this Ebook for FREE, the entire text, in the original typeset format, yellowish tinted pages and all! (I just finished reading this enjoyable book )
Here’s what Shackleton says of the two authors in his introduction:
“It is a curious thing that one of the authors is a scientific man and is capable of counting the minute hairs on the leg of a spider and yet with equal facility can see the broad lines of life. The other is not a scientific man, but, as an artist, depicts what he sees with the same faithfulness as the man who glues his eye to the microscope."
