Query: Canto: An unfortunate redaction of a timeless classic

Don't get me wrong -- "On Growth and Form" is one of my absolute top favorite books of all time. Possibly my favorite book, in fact. This review is a warning to make sure you get the right imprint.Unfortunately some publishers think that they know better than D'Arcy Thompson, and cut out more than half of the original material. After all, nobody these days actually looks at equations, right? Well I do, and the pathetic edition by Canto (368 pages) weighs with less than 33% of the material in the modern unexpurgated reprint by Dover (1116 pages).Amazingly enough, the redacted Canto version costs nearly the same as the Dover complete. If you care about this material, take care to get all of it.
