Strana 75 - I have to thank you for the patience with which you have listened to me, and once again for the many kindnesses you have done Lady Dufferin and myself during our stay amongst you.

Strana 330 - Iron Ship Building, its History and Progress, as comprised in a Series of Experimental Researches on the Laws of Strain; the Strengths, Forms, and other conditions of the Material ; and an Inquiry into the Present and Prospective State of the Navy, including the Experimental Results on the Resisting Powers of Armour Plates and Shot at High Velocities.
Strana 79 - It is hardly possible to avoid associating our conception of an object of definite globular figure, and of such enormous dimensions, with some corresponding attribute of massiveness and material solidity. That the sun is not a mere phantom, but a body having its own peculiar structure and economy, our telescopes distinctly inform us. They show us dark spots on its surface, which slowly change their places and forms, and by attending to whose situation, at different times, astronomers have ascertained...
Strana 243 - practical men ought to have known that the cable was defective, and to have been aware of the locality of the defects before it was laid.
Strana 307 - From these experiments it is evident that wrought-iron girders of ordinary construction are not safe when submitted to violent disturbances equivalent to one-third the weight that would break them. They, however, exhibit wonderful tenacity when subjected to the same treatment with one-fourth the load ; and assuming, therefore, that an iron girder bridge will bear, with this load, 12,000,000 changes without injury, it is clear that it would require 328 years, at the rate of 100 changes per day, before...
Strana 82 - Since the earth revolves about an axis passing through the poles, the equatorial portion of its surface has the greatest velocity of rotation, and all other parts less in the proportion of the radii of the circles of latitude to which they correspond. But as the air, when relatively and apparently at rest on any part of the earth's surface, is only so because in reality it participates in the motion of rotation proper to that part, it follows...
Strana 142 - ... or spindle penetrates the first floor, and from thence ascends to the top of the mill, and in its passage gives motion to the different machines for dressing, cleansing...
Strana 92 - ... already shown that the temperature increases in the ratio of the depth as we penetrate below the earth's surface; and, having ascertained the melting point of any solid body at the pressure of the atmosphere, we had then to determine, by the apparatus just described, the effect that greatly increased pressure had upon the material at different degrees of temperature. For this purpose we commenced with substances such as spermaceti, bismuth, &c., which melt at a low temperature; and, by means...
