The stronglydeveloped bundles contain bast fibers up to i mm. long and 25 ,« broad,with thick walls and narrow lumen, spiral vessels mostly narrower thanthe bast fibers, but with noticeably thick spirals, pitted vessels, and otherless conspicuous elements. 3.

Because of these peculiarities, as well as the dilTiculties ofcutting so soft a tissue when adjoining a hard coat like the endocarp,special care must be exercised in preparing sections.

Closely united with the palisadelayer is the thin, but hard, bulT-colored endocarp resembling in macro-scopic and microscopic structure the endocarp of the apjile. The liberscross one another at various angles, but in the outer layers their generaldirection is longitudinal, while in the inner layer it is transverse. Thefibers of t
