Page 440 - This force consists in the action only; and remains no longer in the body, when the action is over. For a body maintains every new state it acquires, by its vis inertice only. Impressed forces are of different origins as from percussion, from pressure, from centripetal force.
Page 155 - The change in the number of lines of force passing through the coil in the same direction relatively to the coil, produced by the half-turn, is plainly equal to twice as many times the area of the turn of mean area as there are turns in the coil (the effective area swept over) multiplied by the total intensity of the earth's magnetic force at the place of experiment.

Page 440 - An impressed force is an action exerted upon a body, in order to change its state, either of rest, or of moving uniformly forward in a right line. This force consists in the action only and remains no longer in the body when the action is over. For a body maintains every new state it acquires, by its inertia only. Impressed forces are of different origins, as from percussion, from pressure, from centripetal force.

He has also shown how to rule a plane surface with lines so disposed that the grating shall of itself give well-focused spectra. • "In the same way we may conclude that in flat gratings any departure from a straight line has the effect of causing the dust in the slit and the spectrum to have different foci — a fact sometimes observed " (Rowland, " On Concave Gratings for Optical Purposes,
