Seite 242 - As it does not generally break up before it is raised above the surface of the sea, cautiously and anxiously I sank my bucket to a level with the dredge's mouth, and proceeded in the most gentle manner to introduce Luidia to the purer element. Whether the cold air was too much for him, or the sight of the bucket too terrific, I know not, but in a moment he proceeded to dissolve his corporation, and at every mesh of the dredge his fragments were seen escaping.
Seite 151 - ... brass or iron, except daggers : they use ropes made of twisted thongs ; trusting to these they go to war. The mode of fighting of these men is as follows : when they engage with the enemy they throw out the ropes, which have nooses at the end, and whatever any one catches, whether horse or man, he drags towards himself; and they that are entangled in the coils are put to death.
Seite 128 - Actinia crassicornis, that might have been originally two inches in diameter, and that had somehow contrived to swallow a valve of the great scallop (Pecten maximus), of the size of an ordinary saucer. The shell, fixed within the stomach, was so placed as to divide it completely into two halves, so that the body, stretched tensely over, had become thin and flattened like a pancake. All communication between the inferior portion of the stomach and the mouth was of course prevented, yet, instead of...
Seite 128 - ... the animal- had availed itself of what undoubtedly had been a very untoward accident, to increase its enjoyments and its chances of double fare A new mouth furnished with two rows of numerous tentacula, was opened...
Seite 70 - ... imperfectly meet. This inimitable mechanism enables each filament to take up and firmly grasp, at any point of its length, a molecule of sand ; or, if placed in a linear series, a row of molecules. But so perfect is the disposition of the muscular fibres at the extreme...
Seite 242 - I sunk my bucket to a level with the dredge's mouth, and proceeded in the most gentle manner to introduce Luidia to the purer element. Whether the cold air was too much for him or the sight of the bucket too terrific I know not, but in a moment he proceeded to dissolve his corporation, and at every mesh of the dredge his fragments were seen escaping. In despair I grasped at the largest, and brought up the extremity of an arm with its terminating eye, the spinous eyelid of which opened and closed...
Seite 275 - How is this That men of science, osteologists And surgeons, beat some poets in respect For nature,— count nought common or unclean, Spend raptures upon perfect specimens Of indurated veins, distorted joints, Or beautiful new cases of curved spine, While we, we are shocked at nature's falling off, We dare to shrink back from her warts and blains, We will not, when she sneezes, look at her, Not even to say "God bless her"?
Seite 340 - March 7th, 1850, it was observed that he must have come out of his shell in the interval (as the paper had been discoloured, apparently in his attempt to get away) ; but finding escape impossible, had again retired, closing his aperture with the usual glistening film ; this led to his immersion in tepid water, and marvellous recovery. He is now (March 13th, 1850) alive and flourishing, and has sat for his portrait.
Seite 300 - Not all the progeny of the primary impregnated germ-cell are required for the formation of the body in all animals : certain of the derivative germ-cells may remain unchanged and become included in that body which has been composed of their metamorphosed and diversely combined or confluent brethren: so included, any derivative germ-cell or the nucleus of such may commence and repeat the same processes of growth by imbibition, and of propagation by spontaneous fission, as those to which itself owed...
Seite 70 - Terebella nebulosa," writes Dr. Williams, " the tentacula consist of hollow, flattened tubular filaments, furnished with strong muscular parietes, each tentacle forming a band which may be rolled longitudinally into a cylindrical form, so as to inclose a hollow, cylindrical space, if the two edges of the band meet, or a semi-cylindrical space, if they imperfectly meet. This inimitable mechanism enables each filament to take up and firmly grasp, at...
