Scans from classic type-design book

Jason sez, "A colleague of mine introduced me to this great resource - a 1923 edition of P's and Q's - A Book on the Art of Letter Arrangement, by Sallie B. Tannahill. (A former teacher of lettering at Columbia University and a friend of Vojtech Preissig -- the Czech typographer and book designer -- whose work gets sampled frequently throughout the book.) I've posted high-rez scans of Part 1. (23 pages.)" Link (Thanks, Jason!)
