STRUCTURE OF WHALEBONE.
1. Diagram of the matrix of the baleen-plate, the dotted
line, a, showing the outline of the pulp which forms b, the
central fibrous part of the plate; c, external layers of firm
substance formed by the elastic cementing material. 2.
A vertical section of four baleen-plates in situ, the transverse
bar at the top represents the vascular gum from
which the pulps proceed that penetrate the base of the
plates. Below this is shown the elastic substance cementing
the plates together, beyond which the plates project
free and terminate in a fringe of bristles. 3. Transverse
section of a portion of a baleen-plate showing the area of
the tubular cavities of the coarse central fibres, and the
outer, denser substance.
