The book is arranged like this: Drawing principles, character design, then animation. The principles are about constructing forms and wrapping guidelines & features around them properly, facial expressions, building a simple skeletal foundation, how bodies can be drawn, and hands!
The character design section is small, but brilliant. There are great example drawings to work from and trust me when I say the characters are pleasing to look at.
As for the animation section, it's got the essentials for walks, runs, understanding squash & stretch and line of action in movements. It might not have enough movements as one may want, but really, using what you learn here to analyze actions from life will enable you to learn how any movement can be strengthened for animation. I actually haven't started animating yet (still doing the drawing sections), but I know I'll be perfectly fine with just this. Harold Whitaker's "Timing For Animation" does seem like it could be a perfect supplement to this though, so you might wanna check that out as well.
Other pages include things about dialogue phonemes, takes (when's the last time anyone's seen a Tex-Avery-style reaction in a cartoon? learn this and bring it back!) pointers on animation, and, best of all, TONS of characters to practice from.
The book is only eight bucks and, being from Preston Blair, a genius from the golden-age era of animation, you can't go wrong. Buy it, follow everything that he says, draw from each drawing in the book until the concepts seep in, and make some cartoons. Even if you wanna draw comic strips and/or comic books, get this now!
