This French anatomy book has chosen an odd way to illustrate bone structure

This French anatomy book tries to illustrate the similarities between a horse’s bone structure and a humans. Though they’ve gone about it in a very strange way…

For those curious/aroused, a translation:

“Bones of the horse match some of ours. Viewing the picture below, they are indicated by the same color. His knee is your wrist. His shin is our ankle. His hooves are our nails. Horses have, like us, forearms and shoulders.”
