Page 401 - The more thoroughly we comprehend that process of evolution by which things have come to be what they are, the more we are likely to feel that to deny the everlasting persistence of the spiritual element in Man is to rob the whole process of its meaning.
Page 174 - ... all the energy which, according to the first law of Thermo-dynamics, is resident in the coal. On a sounder view of the matter, the efficiency of the steam-engine is found to be so high, that there is no great margin remaining for improvement. The higher initial temperature possible in the gas-engine opens out much wider possibilities, and many good judges look forward to a time when the steam-engine will have to give way to its younger rival.
Page 191 - ... distances from the sun, their diameters and masses. More than thirty years ago, Professor Kirkwood supposed that he had discovered the relation in the analogy which bears his name. The materials for testing and establishing it were then, however, insufficient, and still remain so, leaving far too many of the data uncertain and arbitrary.- Could such a relation be discovered, it could hardly fail to have a most important significance with respect to theories of the origin and development of the...
Page 428 - Pacific coast, possesses, both for the construction and maintenance of a canal, greater advantages, and offers fewer difficulties from engineering, commercial, and economic points of view, than any one of the other routes shown to be practicable by surveys sufficiently in detail to enable a judgment to be formed of their relative merits, as will be briefly presented in the appended memorandum.
Page 250 - This was a continuation of the paper presented to the American association two years ago; and it is sought to show that the view which has been maintained, that a soil is a laboratory and not a mine, is erroneous; for not only the facts adduced by the authors in this and other papers, but the whole history of agriculture so far as we know it, clearly show that a fertile soil is one which has accumulated within it the residue of ages of previous vegetation, and that it becomes less fertile as this...

Page 399 - That the Conference proposes the adoption of a universal day for all purposes for which it may be found convenient, and which shall not interfere with the use of local or other standard time where desirable.
Page 234 - ... Energy become automatic is no longer conscious, or is about to become unconscious. That this is the case is matter of everyday observation on ourselves and on other animals. What the molecular conditions of consciousness are, is one of the problems of the future, and for us a very interesting one. One thing is certain, the organization of the mechanism of habits is its enemy. It is...
