Bat skulls and faces, by E. Dumont at UMass Amherst

My kind of Science despite (or because of?) the fact I couldn't even finish the first chapter of Professor Watson's classic textbook "The Evolutionary Biology of the Gene" -- not having taken biology in high school.   And I gave away my copy of the book almost a year ago.)
