And as the parallel rays are merely perpendiculars to the waves which fall on the concave surface, which waves are parallel to AD, it will be found that as they come successively to encounter the surface AB, they form on reflexion folded waves composed of two curves which originate from two opposite evolutions of the parts of the curve AFE. So, taking AD as an incident wave, when the part AG shall have met the surface AI, that is to say when the piece G shall have reached I, it will be the curves HF, FI, generated as evolutes of the curves FA, FE, both beginning at F, which together constitute the propagation of the part AG. And a little afterwards, when the part AK has met the surface AM, the piece K having come to M, then the curves LN, NM, will together constitute the propagation of that part.
Pinch the nostrils, and try to pronounce slowly the words "Lincoln," "something," or any other words which require the sound of m, ln, or ng. Experiment 190. To illustrate the passage of air through the glottis. Take two strips of India rubber, and stretch them over the open end of a boy's "bean-blower," or any kind of a tube.
The cannon that he passed, with the exception of the Montigny mitrailleuses and the American gatlings, were all beautiful pieces, bronzed and engraved with crown and LN and eagle, but for all their beauty they were only muzzle-loaders. In a little while he came to the head of the column.
If we apply the term "unnatural" to the matter instead of the manner of Carlyle and Tennyson, then away with genius, for intellectual originality is tabooed! no man is privileged to think his own thoughts. That is the law nowadays nowhere except in the sanctum of the Gal-Dal News, where Col. Jenkins takes the editorial eyas and teaches it to soar ln exact imitation of himself.
Now it appears that AK and BL dip down toward the side where the air is less easy to penetrate: for AK being longer than BL, and parallel to it, it follows that the lines AB and KL, being prolonged, would meet at the side L. But the angle K is a right angle: hence KAB is necessarily acute, and consequently less than DAB. If one investigates in the same way the progression of the portion of the wave KL, one will find that after a further time it has arrived at MN in such a manner that the perpendiculars KM, LN, dip down even more than do AK, BL. And this suffices to show that the ray will continue along the curved line which intersects all the waves at right angles, as has been said.
The case of Archbishop Sancroft. ln 1683 King Charles II. issued a Cabinet Order on behalf of the Brethren; the order was accompanied by an account of their distresses; the account was "recommended under the hands" of William Sancroft, Archbishop of Canterbury, and Henry Compton, Bishop of London; and in that account the statement was deliberately made that the Brethren deserved the assistance of Anglicans, not only because they had "renounced the growing errors of Popery," but also because they had "preserved the Succession of Episcopal Orders."
