Page 82 - The outline of the trap, as given on all maps heretofore published, has been incorrect. Instead of the broad area of trap on the southwest limb of the crescent, a belt of hard, black and purplish shale from half to three-quarters of a mile in width extends north from Stanton to Prescott brook. To the west of this shale there is a strip of trap a quarter of a mile wide and a mile and a half long, separated by it from the main mass of the trap. I am at present by no means certain whether this hard,...
Page 326 - ... disease has attracted considerable attention in recent years in many portions of this State, — malarial fever, — and portions of this valley have suffered from it, and severely, when the limited population is taken into account. One farm-house was found not far removed from the meadows, but lying many feet above their level, which, well built and well cared for, had failed to offer adequate protection against an influence which, originating beyond the immediate surroundings of the house itself,...
Page 181 - From an examination of fossils brought from that quarter of the United States, from a personal inspection of some of its strata, and the perusal of most of the publications •which bear a reference to it, I wish to suggest that what is termed the alluvial formation in the geological maps of Messrs.

Page 180 - Reference is made to the wide distribution of fossil shells, and vertebrate remains, and many localities are cited. A second work of the same general character, so far as it relates to the geology, was published in 18'22, by Parker Cleveland, entitled "An Elementary Treatise on Mineralogy and Geology...
Page 162 - The comparative absence of crystalline pebbles and the great abundance of crystalline residuary material indicate that at the beginning of Newark time the rocks were very deeply disintegrated. The thickness of this mantle is best explained by supposing that the adjoining land was at or near base-level. The presence of pebbles several inches in diameter in the Newark beds indicates that during the period of deposition the streams had a velocity not consistent with streams on a peneplain. It is believed,...
Page 211 - Murray and Renard, the authors, present the latest results upon the character and distribution of greensand, and at the same time propose a theory to account for the chemical changes which have taken place to produce the mineral glauconite which characterizes all greensand deposits.
Page 180 - Geological Essay on the Tertiary Formations in America," in the American Journal of Science and Arts for 1824.' This was the first attempt at a correlation of the deposits of the Coastal Plain on scientific grounds, and although thus early in the history of the subject, minute comparisons, which are always unsatisfactory, were made, yet the knowledge of the Maryland Tertiary formations was materially advanced.
