Page 537 - Old Red Sandstone, or Devonian group. True Carboniferous Producti and Spiriferi have been brought home by Sir E. Belcher from Albert Land, north of Wellington Channel ; and hence we may affirm positively, that the true Carboniferous rocks are also present. Here and there bituminous schist and coal are met with ; the existence of the latter being marked at several points on the general chart published by the Admiralty. With palaeozoic rocks are associated others of igneous origin and of crystalline...
Page xxx - that the extent of the range of a species in depth is correspondent with its geographical distribution."* As regards the influence of light, Professor E. Forbes presents us with facts connected with the molluscs and other animals, deserving much attention and extended research, due allowances being made for the modifications produced, as he points out, and to be attributed in many cases...

Some beds have the external characters of " compact bitumen ; " but they generally exhibit in the cross fracture concentric layers, although from their jet-like composition the nature of the woody fibres cannot be detected by the microscope. Some pieces have a strong resemblance to charcoal in structure, colour, and lustre. Very frequently the coal may be named a
Page xxxviii - His attention was directed to the sciences of ornithology and entomology, then of chemistry, and subsequently of mineralogy and geology, including a thorough knowledge of analytical chemistry. In 1797 Prof. Jameson paid his first visit to the island of Arran, and in the following year he published his work on the ' Mineralogy of the Island of Arran and the Shetland Islands, with Dissertations on Peat and Kelp.
Page 166 - Concerning the climate of British New Guinea we are not in possession of sufficient data to enable us to write with any degree of authority, nor yet are we able to contribute anything of special use to climatology. Generally speaking it may be said that the possession is healthy, no dangerous epidemics being known, and, excepting occasional attacks of malarial fever, Europeans suffer no greater inconveniences...
Page 166 - He became a close observer and a broad thinker upon all those subjects which are connected with physico-chemical changes in rocks, and which at that time were the cause of great debate and much dogmatism. His work grew, and in his communication to this Society, entitled " On the Causes producing Foliation in Rocks, and on some observed cases of Foliated Structure in Norway and Scotland,

Page 512 - This coal resembles slate in appearance ; and though it requires a stronger draft than that of an ordinary chimney, yet it is found to answer tolerably well for the blacksmith's forge. Fossil remains are also found here in abundance ; and at the fort there was a pure stone, which had once been a log of wood...
Page xxxiv - Alps, thus pointing to a former connection in that direction. 5. The General Flora. — This universal flora is almost identical as to species with the flora of central and western Europe, and may be properly styled Germanic. The arguments by which these views are maintained are clearly and satisfactorily developed, but must be read and studied to be appreciated. That portion of the paper, however, which relates to the distribution of the marine plants and animals now inhabiting the British seas...
