"Well," replied Pencroft, "we can have North Mandible Cape and South Mandible Cape." "They are inscribed," said Spilett. "There is only the point at the southeastern extremity of the island to be named," said Pencroft. "That is, the extremity of Union Bay?" asked Herbert. "Claw Cape," cried Neb directly, who also wished to be godfather to some part of his domain.
The enlargement may affect only one gland, usually below the angle of the mandible, and remain confined to it, the gland reaching the size of a hazel-nut, and being ovoid, firm, and painless. More commonly the disease affects several glands, on one or on both sides of the neck.
A slight tinge of brownish red is found on some individuals on the crown of the head, and a small patch of orange-yellow extends from the angles of the mouth to the eye. On the base of the bill is a fleshy tubercle or knob, and the upper mandible is curved at the tip. The young of this species are of a bluish-grey colour, with more of the brown-red tinge upon the head.
When one of the vulture-like heads was cut off from the cell, the lower mandible retained its power of opening and closing. Perhaps the most singular part of their structure is, that when there were more than two rows of cells on a branch, the central cells were furnished with these appendages, of only one-fourth the size of the outside ones.
As a rule, it is only in superficially placed bones, such as the tibia, ulna, clavicle, mandible, or phalanges, that tuberculous disease in the marrow gives rise to signs sufficiently definite to allow of its clinical recognition.
In one zoophyte the head itself was fixed, but the lower jaw free: in another it was replaced by a triangular hood, with beautifully-fitted trap-door, which evidently answered to the lower mandible. In the greater number of species, each cell was provided with one head, but in others each cell had two.
Certain compound animals, or zoophytes, as they have been termed, namely the Polyzoa, are provided with curious organs called avicularia. These differ much in structure in the different species. In their most perfect condition they curiously resemble the head and beak of a vulture in miniature, seated on a neck and capable of movement, as is likewise the lower jaw or mandible.
This Sparrow can say 'Peabody, and some kinds of Parrots can repeat whole sentences so as to be understood. That is another thing in which birds' beaks are like our mouths. Now look again can you see anything else about the Sparrow's beak?" "I see a pair of little holes at the root of the upper mandible," said Rap. "Well, those are the nostrils!" said the Doctor.
To sum up, then: in the Right Whale's there is no great well of sperm; no ivory teeth at all; no long, slender mandible of a lower jaw, like the Sperm Whale's. Nor in the Sperm Whale are there any of those blinds of bone; no huge lower lip; and scarcely anything of a tongue. Again, the Right Whale has two external spout-holes, the Sperm Whale only one.
They arise from the palate, and are attached by flexible membrane to the sides of the mandible. Those standing towards the middle are the longest, being about one-third of an inch in length, and they project fourteen one-hundredths of an inch beneath the edge. At their bases there is a short subsidiary row of obliquely transverse lamellae.
