1951 Anatomy Book

I haven't used any reference in a while, so I thought I'd warm up with some sketches from this book I bought back in college called Atlas of Human Anatomy for the Artist by Stephen Rogers Peck.  At the back of the book, there's a section called "Racial Types" with head shots.  Here are sketches of the first two.  Number six is going to be a "generalized mongoloid from mongolia."  I think the book may be a bit dated.

I've drawn this first guy before, but I thought I'd just sketch all 18 of them since I never go to the others the first time around.

This guy looks like he could crush me in a matter of seconds if he wanted to.
