Page 911 - 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 1054 - The character and scope of this series will be best indicated by a reference to the names and subjects included in the subjoined list, from which it will be seen that the cooperation of the most distinguished professors in England, Germany, France, and the United States, has been secured, and negotiations are pending for contributions from other eminent scientific writers.

The Preparation of Potash and Soda Salts, the Manufacture of Sulphuric Acid, and the Recovery of Sulphur from Soda-waste, of course occupy prominent places in the consideration of chemical manufactures.
Page 1052 - I have followed the rule adopted in my first volume, of reprinting the Preface to the tenth edition, by which the reader will be directed to those numerous and important additions and corrections which I found necessary, in consequence of the progress of the science during the fifteen years which separated the ninth and tenth editions.
