Page 86 - Afyoraimu, a companion of Jason in the celebrated voyage of the ship Argo. The art of navigation is supposed to have owed its origin to the expert management of this instinctive sailor. He was observed by the ancients, and subsequent experience has confirmed the observation, to raise himself to the surface of the sea by ejecting a quantity of water, and thus diminishing the specific gravity of his vessel. When floating in a calm, he would throw out two or more tentacula, to serve as oars.

Page 104 - The very peculiar form of the aperture in this genus is a strong and never-failing distinctive feature. This is oblong-oval, or perfectly oval, seldom ovate, and does not gradually contract into a canal, but abruptly opens into it at the same or nearly the same width which it continues to retain throughout the whole length of the beak. Even in the division which is destitute of an exserted beak, the same contour is no less observable. The straightness of the rostrum is a much more questionable mark,...

Page 79 - ... the division B. Strong locomotive powers have been attributed to the Pecten, which are, it is said, exerted in a most singular manner. A very rapid progress is effected by the sudden opening and closing of the shell. This is done with so much muscular force, as to throw it four or five inches at a time. In the water, an equal dexterity is evinced by the animal, in raising himself to the surface, directing his course ad libitum, and suddenly, by the shutting of his valves, dropping to the bottom.
