This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1903 edition. Excerpt: ...the superior corner tooth is still more oblique; it has a notch on its posterior border, and it is separated farther from the intermediate. The inferior tables are round and nearly leveled, or only have traces of the cups. A yellow spot represents the dental star. The superior corner teeth are almost leveled.
