Seite 176 - Malaspina glacier, as from the summit of the Chaix hills, for example, one sees that the great central area of clear, white ice is bordered on the south by a broad, dark band formed of bowlders and stones.
Seite 178 - Malaspina glacier is essentially englacial or subglacial. There is no surface drainage excepting in a few localities, principally on its northern border, where there is a slight surface slope, but even in such places the streams are short and soon plunge into a crevasse or a moulin and join the drainage beneath. On the lower portions of the alpine glaciers, tributary to the main ice sheet, there are sometimes small streams coursing along in ice channels, but these are short-lived.
Seite 109 - If this be not done, the precipitate should be re-dissolved with the least quantity of water, a few drops of hydrochloric acid added, and the precipitation repeated in the original solution. The filtrate is transferred to a weighed platinum dish and evaporated. Water is added before the alcohol has been expelled, and the evaporation continued. The residue is dissolved in water. Sulphuric acid is added in slight excess. This solution is evaporated to dryness, the residue ignited and weighed, and the...
Seite 484 - TYSON, PHILIP T. First report of Philip T. Tyson, State agricultural chemist, to the house of delegates of Maryland, January, 1860. Annapolis, 1860, 8°, XI, 145, and 20 pp.
Seite 39 - ... considered. With regard to the relationships of the mammals of the Lance Creek beds to those of the Puerco and Torrejon extremely diverse views have been expressed. Marsh (Amer. Jour.
Seite 176 - ... border, which, owing to the great obstacles it presents to travel, impresses one as being more extensive than it is in reality. The moraines not only cover all of the outer border of the glacier, but stream off from the mountain spurs projecting into it on the north. As indicated on the accompanying map, one of these trains starting from a spur of the Samovar hills crosses the entire breadth of the glacier and joins the marginal moraine on its southern border. This long train of stones...
Seite 64 - A good pocket-glass will show that the dark figures are striated, with lines at right -angles to the bounding surfaces. When the figure is nearly square the lines extend from each of the four sides, but when much elongated, as at c, they are parallel with the longer sides. Often these lines do not reach the middle of the figure, where only a confused crystallization can be detected. In the interior of the elongated figures the lines are quite irregular, often running together and showing a striking...
Seite 387 - If strontium is present to the amount of 0.001 grm. of the oxide or more a very decided separation takes place. If the amount is smaller it cannot be readily distinguished from the residual spots deposited on the bottom of the tube by the calcium salt. The alcohol containing the calcium salt dissolved is decanted upon a dry filter paper in a dry funnel and the residue washed in the tube with about 5 cm* of absolute ethyl alcohol, this also being filtered into the tube containing the amyl alcohol.
Seite 51 - ... sudden generation of steam under the alcohol. It has been my experience that in the presence of a few drops of water the boiling goes on quietly, the water escaping easily through the amyl alcohol, so that in the course of a few minutes the alcohol reaches its normal boiling temperature (128°-130° C.) In order that the inflammable fumes of the alcohol might not reach the flame during the boiling the beaker was placed upon a piece of asbestos board about 15 cm. square. When the temperature of...
Seite 316 - Definite amounts of a solution of strontium nitrate were measured from burettes into counterpoised beakers and weighed, as already described, the calcium nitrate was then added in solution, and the weight taken again. The water was evaporated and the dry salts dissolved again in the least possible amount of water, and boiled with amyl alcohol (30 cm3) as before.
