Whatever you do be careful not to get the plate connections of the battery reversed. Now connect one of the posts of the rheostat to one terminal of the filament and the other terminal of the filament to the or negative terminal of the A or storage battery and the + or positive terminal of the A or storage battery to the other post of the rheostat.
But the difference in the phaenomena to which it will give rise is immense: in the first place it will develop a vast quantity of physical force cleaving the water in all directions with considerable rapidity by means of the vibrations of the long filament or cilium. Nor is the amount of chemical energy which the little creature possesses less striking.
In some cases by the nutriment originally deposited by the mother the filament acquires parts not exactly similar to those of the father, as in the production of mules and mulattoes. In other cases, the deficiency of this original nutriment causes deficiencies of the extreme parts of the fetus, which are last formed, as the fingers, toes, lips.
For a moment the intolerable glow continued, and then like an extinguished filament it disappeared, revealing a black waste from which blue smoke arose slowly, carrying off with it what remained of vegetation and of human flesh. Of the aviators there was left neither blood nor bone they were consumed as completely as the five souls who had gone inside.
Since the electrons are negative charges of electricity they are not only thrown off by the hot wire but they are attracted by the positive charged metal plate and when enough electrons pass, or flow, from the hot wire to the plate they form a conducting path and so complete the circuit which includes the filament, the plate and the B or plate battery, when the current can then flow through it.
They had sketched them and appeared to be busily weaving in the preliminary bag made of transparent and glittering filament. A few of the creatures began to turn yellow, though as yet they had not devoured their last meal. Jenny picked them up and held them to the morning light.
All that poor filament on which it experiments or gets started must be broken off and saved for embroidery floss, since it is fit neither to be woven into broad goods or twisted into sewing silk. The reeler begins to wind where the end of the filament becomes strong. He then must combine enough fibres of the same size and strength to make a thread uniform in size.
I say slender support, for it is evident that in order to confine the heat more completely to the incandescing body its support should be very thin, so as to carry away the smallest possible amount of heat by conduction. Of all the supports used I have found an ordinary incandescent lamp filament to be the best, principally because among conductors it can withstand the highest degrees of heat.
Even to the end of days, it is pretty certain that the minutest particle of earth that a dewdrop, scarcely distinguishable as a separate object that the slenderest filament of a plant will include within itself secrets inaccessible to man. And yet, compared with the mystery of man himself, these physical worlds of mystery are but as a radix of infinity.
From the filaments of bamboo fiber the next step was to filaments of cellulose in the form of cotton, duly prepared and carbonized. Later came the metalized carbon filament and finally the employment of tantalum or tungsten.
