Only the onion-like bulb remains a little way down. There, postponing the process of vegetation, it waits for the steady rains of the autumn, which will renew its strength and make it burgeon into a sheaf of leaves. How does the Lily-beetle live during the summer, before the return of the green foliage dear to its race? Does it fast during the extreme heat?
A membraneous fold, enclosing the bulb of the eye, stretches across the pupil, dividing the visual apparatus into the upper and lower half; a curious formation, suited to the peculiar habits of the anableps.
It consists of a glass tube with a bulb blown at one end and a small bundle of carbon wool, C, fixed in the center, and exhausted to a pressure of 0.000076 millimeter, or 0.1 M. The negative electrode, A, is formed by coating part of the outside of the bulb with silver, and it is in such a position that the focus of rays falls upon the carbon wool.
You have been told how the rule works. Press the "T" bulb again to click your shutter shut and prepare to set out on a picture taking excursion. Set the time scale at one twenty-fifth of a second, and leave it there. Load up a film. Replace the back of the camera. Take along a tripod. Don't forget that tripod!
When we reduce common air in a bulb to one one-thousandth of its normal density at the sea we get the possibility of continuous incandescent electric light by the vibration of platinum wire. When we reduce it to a tenuity of one millionth of the normal density we get the possibility of the X rays by vibrations of itself without any platinum wire.
But the luminous patches are constantly changing in position, which is especially well observable if one manages to produce very few, and this indicates that the configuration of the electrode is rapidly changing. From experiences of this kind I am led to infer that, in order to be most durable, the refractory button in the bulb should be in the form of a sphere with a highly polished surface.
Our bodies are no more independent organisms than is the lamp bulb: they express the spirit which is the essence of the self, and when that self withdraws the body is as dead as the grass or the worn-out bulb. Yet the failure of the bulb casts no reflection upon the generating station, for the current is still there.
The bulb has a very unpleasant taste, and is somewhat poisonous. It is not eaten by mice or grubs. The black aster beetle is fond of the flowers, and is quite a pest when very abundant. These insects have a preference among colors, and attack the red flowers first, especially a scarlet sort named Bertha.
The leaves, when young, are about six inches in length, of a flat shape and often three inches broad; but, strange to say, they shrivel or die off very early in the season even before the plant flowers, and then it is difficult to find the bulb.
There was nothing to indicate that he had succeeded; the faces of the different groups were still turned his way, and the futile searchlight still wandered around, unable to bring to their view the white tube with its cup-like base. Still waving the wandering beam of white light, the flag-ship passed on, bringing along the second in line, and again Metcalf turned on his bulb.
