Side vii - Address delivered at the Anniversary Meeting of the Geological Society of London on the 20th of February, 1857.
Side 9 - Descriptions of new organic remains collected in Nebraska Territory in the year 1857, by Dr. FV Hayden, geologist to the exploring expedition under the command of Lieut. GK Warren, Top. Engr. US Army, together with some remarks on the geology of the Black Hills and portions of the surrounding country.
Side xix - TRAVELS, comprising OBSERVATIONS made during a RESIDENCE in the TARENTAISE, and various Parts of the Grecian and Pennine Alps, in Savoy, and in Switzerland and Auvergne, in the Years 1820, 1821, and 1822...
Side vii - Observations on the Genus Unio, together with Descriptions of New Species in the Family Unionidae.
Side 141 - Coal-Measures, they hold a position above the workable beds of coal, and that it is not probable a valuable seam of coal will be found north of the southern line of Nebraska. A bed of coal of inferior quality has been wrought near Leavenworth City, Kansas Territory, but it holds a lower geological position than the limestones of the southern portion of Nebraska, the dip of the strata being toward the northeast.
Side 89 - These beds may either belong to the top of the carboniferous system, or to an overlying deposit of the Permian or Triassic age ; and in either case the red sandstones which conformably overlie them will be equivalent to the New Red of western Nova Scotia and Connecticut, and probably Triassic or Permian.
Side 137 - Explanations of a second edition of a geological map of Nebraska and Kansas...
Side xvi - Memoirs of the Geological Survey of the United Kingdom. Figures and Descriptions illustrative of British Organic Remains.
Side 20 - Although they do increase the amount of inorganic matter removed through the urine, yet, as it is the organic matter which is generally considered as contaminating the blood in disease, it is evident they exert no effect whatever in depurating this fluid, but, on the contrary, are positively injurious.
Side 147 - ... remains detected, and those in a fragmentary condition. Passes gradually into the bed below. Most fully developed along the upper portion of Niobrara river and in the region around Fort Laramie. Seen also on White river and on Grindstone Hills. A dull reddish brown indurated grit, with many layers of silico-calcareous concretions, sometimes forming a heavy bedded fine grained sandstone ; contains comparatively few organic remains.
