Page 56 - ... the practicability of applying the treatment in cases where the uterus is impenetrable; the permanence of the benefits derived from the treatment in the mitigation of the symptoms and the reduction of the tumors ; the relation of the menopause to the production or dispersion of fibroid enlargements. It would take up too much of your time if I were to consider these in detail, and it is needless, as Apostoli himself is here, on the invitation of your president, to give any required information....
Page 25 - In the former, the flow of the tide always creates a strong current upwards, whilst in the Amazons the turbid flow of the mighty stream overpowers all tides, and produces a constant downward current. The colour of the water is different, that of the Para being of a dingy orange brown, whilst the Amazons has an ochreous or yellowish clay in it.
Page 128 - Anderson, the eminent telegraph-engineer, says, in a letter to me : — " Perhaps the most marked experience we have had of currents at great depths was in the case of the Falmouth cable near Gibraltar. At 500 fathoms the wire was ground like the edge of a razor, and we had to abandon it and lay a cable well inshore. Captain Nares, of the surveying ship
Page 15 - If we take the mean annual discharge of the Mississippi at 541,666,666,666 tons* in round figures, there are 150 million tons of solids in solution per annum poured into the Gulf of Mexico by the Mississippi, a truly remarkable quantity, which if reduced to rock at 15 feet to the ton is represented in round numbers by 80 square miles, 1 foot thick. According to Messrs. Humphreys and Abbot the proportion of sedimentary matter to the water by weight is...
Page 128 - ... about the 25th parallel, where it attains a depth of 6267 metres. Then it gradually rises towards the Azores and the 35th parallel, where it is about 3000 metres. These results are far from agreeing with the curves indicated on the most recent bathymetric . charts. The bed of the Sargassum Sea seems formed of a •thick layer of a very fine mud of a pumice nature, covering fragments of pumice and volcanic rocks.
Page 14 - I found great difficulty in obtaining answers to my various questionings. Years elapsed and letters innumerable were written before I could alight upon any analyses of the waters of the Mississippi, reliable or otherwise. At last through the kindness of Prof. JW Spencer, of the State University of Missouri, I was supplied with the following analysis: Analysis of Mississippi water near Carrolton, a few miles above New Orleans...
Page 30 - Gulf-stream slope, in this region, and the remarkable absence of actual mud or clay deposits indicate that there is here, at the bottom, sufficient current to prevent, for the most part, the deposition of fine argillaceous sediments over the upper portion of the slope, in 65 to 150 fathoms. Such materials are probably carried along till they eventually sink into the greater depths nearer the base of the slope, or beyond, in the ocean basin itself, where the currents are less active.
Page 119 - ... extended plain sloping, and that not rapidly, at the borders towards the continental shore lines. The more it is found necessary to sound the ocean, the more apparent, I am convinced, will these inequalities become. A very good example of the truth of this remark has just come to hand, as Prof. Verrill, describing the work of the US steamer "Albatross " in 1884,* says that five stations in depths below 2,000 fathoms were between N. lat. 36° 05' 30" and 37° 48
Page 16 - Mississippi is lowered at the rate of one foot in 6,000 years, but this rate has been calculated from the removal of sediment alone; if we add to the matter removed mechanically that in solution it will raise the rate to one foot in 4,500 years.
Page 57 - ... looking like fine ground glass. 3. Sand mechanically broken into sharp angular chips, showing a glassy fracture. 4. Sand having the grains chemically corroded, so as to produce a peculiar texture of the surface, differing from that of worn grains or crystals. 5. Sand in which the grains have a perfect crystalline outline, in some cases undoubtedly due to the deposition of quartz over rounded or angular nuclei of ordinary non-crystalline sand.
