Página i - GENTLEMEN, — As you will perceive by the enclosed Instrument of Trust, I wish to place in the hands of yourselves, and your successors, the sum of One Hundred and Forty Thousand Dollars, for the PROMOTION OF SCIENCE AND USEFUL KNOWLEDGE IN THE COUNTY OF ESSEX. Of this, my native County, I have always been justly proud, in common with all her sons, remembering her ancient reputation, her many illustrious statesmen, jurists, and men of science, her distinguished record from the earliest days of our...
Página 247 - As it does not generally break up before it is raised above the surface of the sea, cautiously and anxiously 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...
Página 373 - But cawing rooks, and kites that swim sublime In still repeated circles, screaming loud, The jay, the pie, and e'en the boding owl, That hails the rising moon, have charms for me.
Página 247 - The first time I ever took one of these creatures I succeeded in getting it into the boat entire. Never having seen one before, and quite unconscious of its suicidal powers, I spread it out on a rowing-bench, the better to admire its form and colours. On attempting to remove it for preservation, to my horror and disappointment I found only an assemblage of rejected members.
Página 361 - The scenery much resembled that in the Black Canyon, excepting that the rapid descent, the increasing magnitude of the colossal piles that blocked the end of the vista, and the corresponding depth and gloom of the gaping chasms into which we were plunging, imparted an unearthly character to a way that might have resembled the portals of the infernal regions.
Página 491 - ... and the animal came more frequently to the surface of the water for air. As the change went on the dark spots increased in number and size, and gradually extended over the whole upper part of the body. The membrane on the back and tail entirely disappeared, leaving in its place in the dorsal region a sharp groove. The...
Página 269 - ... with paler longitudinal lines. Is it alive? It hangs helpless and motionless, a mere velvet string across the hand. Ask the neighbouring Annelids and the fry of the rock fishes, or put it into a vase at home, and see. It lies motionless, trailing itself among the gravel ; you cannot tell where it begins or ends ; it may be a dead strip of sea-weed, IJimanthalia lovea perhaps, or Chorda filum ; or even a tarred string.
Página 137 - But forth unto the darksome hole he went, And looked in: his glistring armor made A litle glooming light, much like a shade...
Página 263 - ... sulphuretted hydrogen, blackness, and evil smells. Put your weeds into your tank, and settle them at the bottom ; which last, some say, should be covered with a layer of pebbles : but let the beginner leave it as bare as possible ; for the pebbles only tempt cross-grained annelids to crawl under them, die, and spoil all by decaying : whereas if the bottom of the vase is bare, you can see a sickly or dead inhabitant at once, and take him out (which you must do) instantly. Let your weeds stand...
Página 635 - But the structure of the tongue itself (labium,) is most curious. When the fly settles upon a lump of sugar or other sweet object, it unbends its tongue, extends it, and the broad knob-like end divides into two broad, flat, muscular leaves which thus present a sucker-like surface, with which the fly laps up the liquid sweets.
