But we will not anticipate; and we will place the huntress and her game together under the bell-glass. I recommend this experiment to whoever would wish to see with what perfection in the art of attack and defence a Hunting Wasp wields the stiletto.
A young petiole, when rubbed, became slightly curved in 17 m.; and afterwards much more so. It was nearly straight again in 8 hrs. Tropaeolum tuberosum. On a plant nine inches in height, the internodes did not move at all; but on an older plant they moved irregularly and made small imperfect ovals. These movements could be detected only by being traced on a bell-glass placed over the plant.
Two New England consciences Inexhaustible faith and energy Deep and abiding love of England "How the Water Comes Down at Lodore" "He took an' he let go" Naked mountains The unsentimental little quadruped The human element in things sticks The coasts of England A string of sleepy donkeys Unutterable boy-thoughts Grins and chuckles like an ogress Hideous maternal parody The adorable inverted bell-glass Strange things happen in the world An ominous clouding of the water Something the world has never known Overweening security An admonition not to climb too high How vice may become virtue by repetition Corporal Blair's chest Black- Bottle Cardigan Called to Lisbon.
Wilhelm, experimenting with air-dried field-earth, exposed to air in contact with water and protected by a bell-glass, found that the absorption amounted in seventy-two hours to two per cent. and a very small fraction, nearly the whole of which was taken up in the first forty-eight hours.
The other Hunting Wasps that pursue the chase far afield grip, drag, carry their prey, after depriving it of movement, each in her own fashion and, laden with their burden, make prolonged attempts to escape from the bell-glass and to gain the burrow. Discouraged by these futile endeavours, they abandon them at last.
If fresh leaves are placed in a bell-glass containing air charged with seven or eight per cent. of carbonic acid, and exposed to the light of the sun, it will be found that a large proportion of the carbonic acid will have disappeared, and will be replaced by pure oxygen. But this change will not be effected in the dark, nor by any degree of artificial light.
The basal portion of the main petiole is much less sensitive, but will clasp a stick against which it presses. The leaves, whilst young, are continually and spontaneously moving slowly. A bell-glass was placed over a shoot secured to a stick, and the movements of the leaves were traced on it during several days.
A knotty ungovernable-looking branch five to eight feet thick may be seen pushing out abruptly from the smooth trunk, as if sure to throw the regular curve into confusion, but as soon as the general outline is reached it stops short and dissolves in spreading bosses of law-abiding sprays, just as if every tree were growing beneath some huge, invisible bell-glass, against whose sides every branch was being pressed and molded, yet somehow indulging in so many small departures from the regular form that there is still an appearance of freedom.
Here, then, as cordially as with us man abhors an acoustic vacuum, and when Nature has put her icy bell-glass over the noises of the field, he must needs invent some jingle to wile his ears withal. Once past the houses we came upon a strip of paddyfields that bordered the mountain slope to the very verge of the tide.
Chance often has a surprise in store which sets us on the right road when we have been seeking it in vain. One afternoon, while trying to determine whether sight plays any part in the search for the female once the males had entered the room, I placed the female in a bell-glass and gave her a slender twig of oak with withered leaves as a support.
