Page 545 - There went up a smoke out of his nostrils, And fire out of his mouth devoured; Coals were kindled by it. He bowed the heavens also, and came down; And darkness was under his feet. And he rode upon a cherub and did fly; Yea, he did fly upon the wings of the wind.
Page 293 - "Gneissoid series in Nova Scotia and new Brunswick, supposed to be the equivalents of the Huronian (Cambrian) and Laurentian.
Page 307 - To give a stronger impulse and a more systematic direction to scientific inquiry, — to promote the intercourse of those who cultivate Science in different parts of the British Empire, with one another and with foreign philosophers, — to obtain a more general attention to the objects of Science, and a removal of any disadvantages of a public kind which impede its progress.
Page 549 - H, 1880. IT is not my intention in this paper to enter into a minute account of the construction and comparison of the various standards of length which have been made the basis of measurements, either in trigonometrical surveys of the earth's surface, or in more strictly physical investigations. Many of these possess a certain historical interest, even when they have...
Page 10 - It consists essentially of a cartilaginous cushion, supporting, as on a pulley, an elastic strap, which bears a long series of transversely disposed teeth. The ends of the strap are connected with muscles attached to the upper and lower surface of the hinder extremities of the cartilaginous cushions ; and these muscles, by their alternate contractions, cause the toothed strap to work backwards and forwards over the end of the pulley formed by its anterior end. The strap consequently acts...
Page 192 - The author described the arrangement of these parts in detail, and indicated their agreement with the same parts in Osmunda regalis. He did not venture to refer the Fern, to which this stem had belonged, positively to the genus Osmunda, but preferred describing it as an Osmundites, under the name of 0. Dowkeri. The specimen was silicified, and the author stated that even the...
Page 104 - ... vitrified aspect of the felspar crystals of many trachytes ; the broken and dislocated appearance of the leucites, felspars, and other crystals in many basalts ; the frequent arrangement of the longest axes of such crystals in the direction of the rock, that is, of the movement of the lava when liquid ; the finer grain often exhibited towards the tail or extremity of a current than at its source, as if the crystals had been broken up by friction as the matter moved on ; the brecciated lavas which...
Page 254 - ... that those bones were laid there. The branches of the fern in every layer as we opened them were very distinguishable, as were the seeds of the rushes and the tops of boughs. The whole matter smelt very sour as it was dug ; and, tracing it, I found it 34 feet long and about 20 to 22 feet broad.
Page 493 - It differs from the adult simply in possessing a less number of abdominal feet (gills), and in having only a very rudimentary spine. Previous to hatching, it strikingly resembles Trinucleus and other trilobites, suggesting that the two groups should, on embryonic and structural grounds, be included in the same order, especially now that Mr. E. Billings has demonstrated that Asaphus possessed eight pairs of five-jointed legs of uniform size.
Page 305 - His home was full of maps, sections, models and collections of fossils ; and his hourly talk was of the laws of stratification, the succession of organic life, the practical value of geology ; its importance in agriculture, engineering and commerce ; its connection with physical geography, the occupations of different people, and the distribution of different races. In this happy dream of the future expansion of geology, his actual professional work was...
