Page 68 - Report on the geology of the area covered by the Seine River and Lake Shebandowan map sheets, comprising portions of Rainy River and Thunder Bay districts, Ontario.
Page 112 - All the islands we examined are, without exception, formed of tertiary coralliferous limestone, which has been elevated to a greater or less extent above the level of the sea, and then planed down by atmospheric agencies and submarine erosion, the greatest elevation being at Makatea (about 230 feet), and at Niau, where the tertiary coralliferous limestone does not rise to a greater height than 20 feet. At Rangiroa it was 15 to 16 feet high.
Page 221 - THE KINETIC THEORY OF GASES. Elementary Treatise, with Mathematical Appendices. By Dr. OSKAR EMIL MEYER, Professor of Physics at the University of Breslau. Second Revised Edition. Translated by ROBERT E. BAYNES, MA, Student of Christ Church, Oxford, and Dr. Lee's Reader in Physics.
Page 84 - William was a Presbyterian of the old school and strongly opposed to all theories of the evolution of man from brute ancestors, nor would he allow anything more than a very moderate antiquity for the species. The study of geology, too, he would have emancipated from " that materialistic infidelity which by robbing nature of the spiritual element and of its presiding divinity makes science dry, barren, and repulsive and diminishes its educational value.
Page 443 - The sign of this correction term shows that a real gas will effuse more rapidly or more slowly than an ideal gas of equal density and specific heat ratio according as K is positive or negative. (8.) The suggestion is made that possibly the anomalous results obtained with carbon dioxide and helium may be thus explained. The deviations of the observed results from the results calculated for an ideal gas are, in the case of CO2, in qualitative accordance with the theory proposed.
Page 371 - I have visited during this trip ; that we must look to submarine erosion and to a multitude of local mechanical causes for our explanation of the formation of atolls and of barrier and encircling reefs, and that, on the contrary, subsidence has played no part in bringing about existing conditions of the atolls of the South and Central Pacific.
Page 295 - ... .and that even when the most favourable conditions are selected, and the intensity of current and the length of the arc are maintained constant, it is difficult to obtain consistent results, variations of over 5 per cent, being by no means unfrequent. The crater of the arc does not, therefore, possess the qualities required of a standard. Incidentally the experiments made confirm the theory that the crater of the arc is at the temperature of volatilization of carbon.
Page 76 - These are the details of the experiment. As it is not likely to be often repeated, I have thought it worth while to place them on record as precisely as possible. The first question that suggests itself is, what evidence we have for believing that the seeds have actually been brought to the almost inconceivable temperature with which they were surrounded. That they were so brought, Professor Dewar himself has not a shadow of doubt. That substances at widely extreme temperatures can remain in juxtaposition...
Page 39 - It became very evident, after we had examined the south shore of the lagoon, that the ledge underlying the north shore is the remnant of a bed of Tertiary coralliferous limestone, which at one time covered the greater part of the area of the lagoon, portions of which may have been elevated to a considerable height.
Page 443 - Effect. As foreseen by the theory, the rate of effusion of argon, when compared with that of oxygen, is very considerably greater than the value as calculated by the law of the inverse square root of the density. The foregoing experiments agree uniformly in showing that the deviation amounts to 3J per cent. On the other hand, the results obtained with helium, although not very uniform, show pretty conclusively that its behaviour is unlike that of argon. According to the theory, however, it should...
