What reading level is Contributions to the Paleobotany of Peru Bolivia And Chile Five Papers book?
To quickly assess the difficulty of the text, read a short excerpt:
PLATE IV Fig. 3 Leaves of medium size, oval in general outline, widest at or slightly above the middle, with full rounded entire margins 130 STUDIES IN GEOLOGY, No. 4 narrowing about equally distad and proximad. Apex broadly cuneate pointed. Base slightly more extended than the apex, about equally cuneate pointed or slightly narrower. Texture subcoriaceous. Length about 10 cm. Maximum width about 4. 4 cm. Petiole short and stout, about 5 mm. In length. Midrib stout, curved, prominent on the low...er surface of the leaf. Secondaries fairly stout; the basal pair diverge from the midrib at considerable but unequal distances above the base and are hence not opposite ; their angle of divergence is less than is the case with the balance of the secondaries and a wide interval separates them from the secondaries next above; they pursue regularly curved ascending courses sub- parallel with the lower lateral margins and are eventually camptodrome above the middle of the leaf. A very slight enlargement and development of these would make the leaf have distinctly tripalmate venation.
