With numerous Illustrations and Folding Plates. Second Edition, carefully revised. I2mo, y. 6d. cloth boards. "Mr. Davies has written a useful and practical hand-book on an important industry, with all the conditions and details of which he appears familiar.
Page 116 - I of the American Journal of Mathematics he has a note " On a Class of Transformations which Surfaces may Undergo in Space of more than Three Dimensions," in which he shows, for instance, that if a fourth dimension were added to space, a closed material surface (or shell) could be turned inside out by simple flexure without either stretching or tearing.
Page 330 - Not unfrequently in the mountain districts broad beams apparently of bluish light may be seen extending from the zenith downwards, converging and narrowing as they approach the horizon. This ray-like appearance is very similar to that seen before sunrise ; only the point from which the rays proceed is opposite the sun : the rays themselves are very broad and blue in colour ; and the spaces between them have the ordinary illumination of the rest of the sky. If we suppose in this instance that the...
Page 240 - I found that one ounce of lead was not sufficient on a surface of contact 1 centimetre square to maintain constant contact; and it was only by removing the musical box to a distance of several feet that I was enabled to preserve continuity of current with a moderate pressure. I have spoken to forty microphones at once, and they all seemed to respond with equal force. Of course there must be a loss of energy in the conversion of molecular vibrations into electrical waves, but it is so small that I...

I have spoken to forty microphones at once ; and they all seemed to respond with equal force. Of course there must be a loss of energy in the conversion of molecular vibrations into electrical waves ; but it is so small that I have never been able to measure it with the simple appliances at my disposal. I have examined every portion of my room — wood, stone, metal, in fact all parts — and...

The result was perfectly satisfactory ; that is, Mr. Bell wrote down my queer and purposely exaggerated pronunciations and mispronunciations, and delicate distinctions, in such a manner that his...
