Biometry, 3rd edition, by R.R. Sokal and F.J. Rohlf, published by W.H. Freeman and Co.
That is how it was cited. There was a Biometry, 2nd edition that is out of print and the book you mention is 3rd edition as listed on Amazon so hopefully the one you mention is the correct one. Sorry but I only found a brief sketchy reference to the book so I can't be sure.
