UPDATE 7/26/2010
from Human Structure and Shape by John Hull Grundy, first published in 1982 in hardback by Noble Books in Chilbolton, Hampshire, UK. You may be able to find the entire book through rare book finders or the internet, but few copies exist, the author is deceased, and the book itself is out of print. It's on eBay right now for $795.
