I should have got Animals in Motion that is over 400 pages, though this book was just fine, it was, I presume, the appetizer for his other book which had four times as many illustrations for only a few dollars more. Perhaps I'll sell this one and buy the other one and see for sure. Otherwise, its a great book. It had about 13 pages just horses, then went to a donkey and cats, lions, camels and other stuff I didn't need nor was interested in. I wonder if the other book has MORE horses? There was an introduction of one page, a short summary, and the rest was whole pages filled with movie clip style shots that were about 2" SQUARE each frame, maybe 8 - 12 frames per page, each page one animal in motion. I need to see more, more and more of everything, but that's because I'm drawing horses and wanted to see 30 movement shots of one animal instead of 8. The more I have to choose from the better, so guess I'm gonna use the images here until I need to move up to the next Muybridge book, the 418 page one, Animals in motion which I now realize I should have got in the first place.
