shell-like form of the tympanic bone) for intensifying and strengthening the sound-waves as they are received from the water .

It seems, therefore, perfectly evident that whales must hear when in the water . This inference is confirmed by the comparatively small development of the other sense-organs . The eye, for instance, is very small, and can be of little use even at the comparatively small depths to which whales are now believed to descend . Again, the sense of See also:

• SMELL (connected etymologically with " smoulder " and " smoke ")

smell, judging from the rudimentary condition of the olfactory organs, must be in See also:

• ABEYANCE (O. Fr. abeance, " gaping")

abeyance; and whales have no sense-organs comparable to the lateral-line-system of fishes . Consequently, it would seem that when below the surface of the water they must depend chiefly upon the sense of hearing . Probably this sense is so highly developed as to enable the animals, in the midst of the vibrations made by the See also:

• SECTION
• SECTION (Lat. sectio, cutting, secare, to cut)

section is that of the whalebone whales, or Mystacoceti, in which no functional teeth are developed, although there are tooth-germs during foetal life . The palate is furnished with plates of baleen or whalebone; the skull is symmetrical; and the nasal bones form a roof to the nasal passages, which are directed upwards and forwards . The maxilla is produced in front of, but not over, the orbital process of the frontal . The lacrymal is small and distinct from the fugal . The tympanic is welded with the periotic, which is attached to the base of the skull by two strong diverging processes .

The olfactory organ is distinctly developed . The two halves of the lower jaw are arched outwards, their anterior ends See also:

• MEETING (from " to meet," to come together, assemble, 0. Eng. metals ; cf. Du. moeten, Swed. mota, Goth. gamotjan, &c., derivatives of the Teut. word for a meeting, seen in O. Eng. Wit, moot, an assembly of the people; cf. witanagemot)

meeting at an angle, and connected by fibrous tissue without any symphysis . All the ribs at their upper extremity articulate only with the transverse processes of the vertebrae; their capitular processes when present not articulating directly with the bodies of the vertebrae . The sternum is composed of a single piece, and articulates only with a single pair of ribs; and there are no ossified sternal ribs . External openings of nostrils distinct from each other, See also:

• LONGITUDINAL

longitudinal . A short conical caecum . When in the foetal state these whales have numerous minute teeth lying in the dental groove of both upper and lower jaws . They are best developed about the middle of foetal life, after which they are absorbed, and no trace of them remains at the time of See also:

• BIRTH (a word common in various forms to Teutonic languages from the root of the verb " to bear ")

At the inner edge of each principal blade are two or three much smaller or subsidiary See also:

It differs also greatly in other respects, being short, thick, coarse, and stiff in some cases, and greatly elongated and highly elastic in those species in which it has attained its fullest development . Its function is to See also:

• STRAIN (through O. Fr. straindre, estraindre, mod. i treindre, from Lat. stringere, to draw tight, related to stress, stretch, string, &c.)

strain the water from the small marine molluscs, crustaceans, or fish upon which the whales subsist .

• TONGUE (O. Eng. lunge)

tongue, so as to diminish the cavity of the mouth, the water streams out through the narrow intervals between the hairy fringe of the whalebone blades, and escapes through the lips, leaving the living prey to be swallowed . Although sometimes divided into two families, Balaenidae and Balaenopteridae, whalebone-whales are best included in a single See also:

family group under the former name . The typical members of this family are the so-called right-whales, forming the genus Balaena, in which there are no folds on the See also:
