66. lappuse - Yet nature is made better by no mean, But nature makes that mean: so, o'er that art, Which you say adds to nature, is an art That nature makes. You see, sweet maid, we marry A gentler scion to the wildest stock, And make conceive a bark of baser kind By bud of nobler race: this is an art Which does mend nature, — change it rather; but The art itself is nature.
3. lappuse - The world goes ahead because each of us builds on the work of our predecessors. "A dwarf standing on the shoulders of a giant can see farther than the giant himself.
122. lappuse - Are not gross bodies and light convertible into one another, and may not bodies receive much of their activity from the particles of light which enter their composition ? ... The changing of bodies into light and light into bodies is very conformable to the course of Nature, which seems delighted with transmutations.
162. lappuse - In verbis etiam tenuis cautusque serendis, Dixeris egregie notum si callida verbum Reddiderit junctura novum. Si forte necesse est Indiciis monstrare recentibus abdita rerum, Fingere cinctutis non exaudita Cethegis Continget, dabiturque licentia sumpta pudenter ; Et nova fictaque nuper habebunt verba fidem si Graeco fonte cadant, parce detorta.
85. lappuse - How these attractions may be performed, I do not here consider. What I call 'attraction' may be performed by impulse, or by some other means unknown to me. I use that word here to signify only in general any force by which bodies tend toward one another, whatsoever be the cause.
400. lappuse - A Leyden jar of one square foot coated surface has its interior connected with a Cuthbertson's electrometer, between which and the outer coating of the jar are a pair of discharging balls fixed at a certain distance (about \ an inch apart).
204. lappuse - Wislicenus consider to be non-nitrogenized food ; the results of its consumption being force, or work, heat and carbonic acid. They adopt the view " that the substances, by the burning of which force is generated in the muscles, are not the albuminous constituents of the tissues, but non-nitrogenous substances, either as fats or hydrates of carbon.
162. lappuse - ... thus, when a substance, such as sulphuret of antimony, is electrified, at the instant of electrisation it becomes magnetic in directions at right angles to the lines of electric force ; at the same time it becomes heated to an extent greater or less according to the intensity of the electric force. If this intensity be exalted to a certain point the sulphuret becomes luminous, or light is produced : it expands, consequently motion is produced ; and it is decomposed, therefore chemical action...
203. lappuse - ... present resources exhausted, the more we can invent new modes of conversion of forces, the more prospect we have of practically supplying such want. It is but a month from this time that the greatest triumph of force-conversion has been attained. The chemical action generated by a little salt water on a few pieces of zinc will now enable us to converse with inhabitants of the opposite hemisphere of this planet, and " Put a girdle round about the earth in forty minutes.
xiv. lappuse - ... electricity magnetism; and so of the rest. Cause and effect, therefore, in their abstract relation to these forces, are words solely of convenience. We are totally unacquainted with the ultimate generating power of each and all of them, and probably shall ever remain so; we can only ascertain the normse of their action: we must humbly refer their causation to one omnipresent influence, and content ourselves with studying their effects and developing, by experiment, their mutual relations.
