Supposing, then, that we take a plate of a wedge form, which grows gradually thicker from edge to back, we ought to expect, in red light, a series of recurrent bands of light and darkness; the dark bands occurring at thicknesses which produce retardations of one, three, five, etc., half wave-lengths, while the bright bands occur between the dark ones.
The asbestos lining, shown in fig. 13, may be of various thicknesses, according to the size of the chimney and the tube; the reason for this will be apparent to many; but being a most important factor in the heating of the tube, and consequently the working of the engine, it will be advisable to deal with this point more fully.
In the softest places, rude gates or hurdles, some 8 or 9 feet long by 4 feet wide, interwoven with heather, were laid in double thicknesses, their ends overlapping each other; and upon this floating bed was spread a thin layer of gravel, on which the sleepers, chairs, and rails were laid in the usual manner. Such was the mode in which the road was formed upon the Moss.
"It's no use your a-calling o' me, Sir! His lines are as few as can be he is most economical in this respect and loves to leave as much white paper as he can; but one feels in his best work that one line more or one line less would impair the perfection of the whole that of all the many directions, curves, and thicknesses they might have taken he has inevitably hit upon just the right one.
Put the seeds on several thicknesses of moist blotting paper on a plate, cover them with more moist paper, and invert another plate over them, taking care to allow the free entrance of air. If possible, it is by far the best way to have the seeds growing in the schoolroom, and make it a regular custom for the pupils to observe them every morning and take notes of their growth.
The following instance will show you the frightful destructiveness of the French shells: A dugout five meters deep, surrounded by two meters fifty centimeters of earth and two thicknesses of heavy timber, was broken like a match."
"The plates into which the substance is divisible have been formed in succession, and certain intervals of time have elapsed between their formation; in general, every two contiguous laminae are separated by a thin iridescent film, varying from the three to the fifty millionth part of an inch in thickness, and producing all the various colours of thin plates which correspond to intermediate thicknesses: between some of the laminae no such film exists, probably in consequence of the interval of time between their formation being too short; and between others the film has been formed of unequal thickness.
This gradually increased, in the same manner as the positive current, until it also, in turn, produced its flame of fire, and burned through many thicknesses of the prepared paper; it then subsided, again to be followed by the positive current. This state of things continued during the entire evening, and effectually prevented any business being done over the wires."
Denison had half-a-dozen cartridges in his hand; each one was tightly enveloped in many thicknesses of paper, seized round with twine, and had about six inches of fuse, with the ends carefully frayed out so as to light easily. "Give me some of those," said Saunderson.
Max had long ago showed the greenhorns how to fold this, so that while one part lay between their bodies and the ground, they would have several thicknesses over them, to be pulled up as the night grew cooler. Besides, each boy had a rubber poncho in which the blanket could be wrapped during the day, to keep it from getting wet while in the canoes.
