Page 27 - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
Page iv - Society answerable, for the certainty of the facts, or propriety of the reasonings, contained in the several Papers so published, - which must still rest on the credit or judgment of their respective Authors.
Page 392 - ... he before knew from feeling, he would carefully observe, that he might know them again; but having too many objects to learn at once, he forgot many of them; and (as he...
Page 430 - Exper. 3. Experiments analogous to the former, and equally simple, may also be made with many metallic solutions. If, for instance, the solution contains copper, it will be precipitated by a piece of iron, and appear on its surface. Upon silver merely immersed in the same solution, no such effect is produced ; but, as soon as the two metals are brought into contact, the silver receives a coating of copper.
Page 432 - I considered that the decomposition must depend on duly proportioning the strength of the charge of electricity to the quantity of water, and that the quantity exposed to its action at the surface of communication depends on the extent of that surface...
Page 293 - ... two cases, it would not admit of any chasms or openings. Therefore, it must be concluded that this shining matter exists in the manner of empyreal, luminous, or phosphoric clouds, residing in the higher regions of the solar atmosphere. The Doctor then is of opinion that the spots are only accidental openings between the luminous clouds, through which we behold the opaque body of the sun, or the inferior less luminous clouds; hence the spots appear of different shades. The Doctor...
Page 431 - The explanation here given receives additional confirmation from comparative experiments, which I have made with common electricity ; for it will be seen that the same transfer of chemical power, and the same apparent reversion of the usual order of chemical affinities in the precipitation of copper by silver, may be effected by a common electrical machine.
Page 316 - To those acquainted with agriculture who may remark that wheat is well known to grow in climates much colder than ours, and that a proper distribution of rain and dry weather are probably of much greater consequence than the absolute quantity of light and heat derived from the sun, I shall only suggest that those very circumstances of proper alternations of...
Page 329 - Ac velut ille canum morsu de montibus altis actus aper, multos Vesulus quem pinifer annos defendit multosque palus Laurentia, silva pastus harundinea, postquam inter retia ventum est, 710 substitit infremuitque ferox et inhorruit armos, nee cuiquam irasci propiusque accedere virtus, sed iaculis tutisque procul clamoribus instant...
