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. |
