Page 134 - FISHER, Hon. Fellow of Jesus College. I wish to correct an error in a paper " On the hypothesis of a liquid condition of the earth's interior in connection with Professor Darwin's theory of the genesis of the moon," read in May last year. It is unnecessary to go into all the geological arguments which favour that view. Many of them will be found well set forth in an article in the Fortnightly Review1 by Dr Alfred Russel Wallace, FRS The strongest argument on the other side is admitted to be the existence...
Page 113 - Duck, is such as almost to preclude the supposition of their being due to purely aqueous transport and deposition. It is, however, very suggestive of the results likely to be produced by marine glacial transport ; and the mixture of coarse and fine, angular, and waterworn material, much of which has clearly been derived from distant sources, would also favour this supposition.
Page 166 - K is constant. This is equivalent to supposing the current sheet to be a homoeoidal shell, for the thickness of such a shell at any point is proportional to the perpendicular from the centre on the tangent plane at that point, ie inversely proportional to L, so that if the sheet be made of a homogeneous conducting substance its specific resistance at any point will vary as L. Let...
Page 156 - England, whilst the upper unfossiliferous beds may be the equivalents of the Danian Beds. The strata are, on the whole, of shallow-water origin, and were deposited in shallow bays in the Upper Cretaceous sea of Southern and Central Europe, on the northern flanks of the Eastern Alps. Probably towards the close of Upper Cretaceous times the southern area of the Gosau District was cut off from the sea to form a lakebasin in which the upper unfossiliferous series was deposited. 2. "Artesian Borings at...
Page 20 - ... gleichnamig sind". Nur einmal fand er eine Blüte, „wo ein längeres und ein kürzeres Staubblatt gänzlich fehlten, während die beiden anderen sich normal ausgebildet zeigten". Willis hat (92, b, S. 20) diese Angabe im ganzen für richtig erklärt, seine eigenen Zahlen stimmen aber nicht recht dazu. „Out of 265 abnormal flowers, 179 had the abortion symmetrical. Of these, 142 were female, 26 had the two anterior (long) stamens missing, and 11 the two posterior (short).
Page 11 - Examination of this material shows that large brood chambers are formed at the margin of the disc during the later stages of growth. These are at first lined with a thin layer of protoplasm. At a later stage the central region of the disc is found to be empty, and the whole of the protoplasm is massed in the brood chambers in the form of spores. The spores have the structure of the "primitive disc," which during the early stages of growth Л the Orhitoliles occupies the centre of the shells.
Page 230 - Wahsatch according to King are about 50,000 ft. thick. The Cretaceous alone, in the Coast Range of California near the Bay of San Francisco, according to Whitney, are 20,000 ft. and in Shasta Co. according to Diller are 30,000 ft.
Page 128 - The author recorded his thanks to Prof. O. Lodge, FRS, for kindly exposing the plates to the electric spectrum for him, with most successful results. The author also found that the water of the Thames, examined in August and...
Page 128 - October, and differences were observable in the aspect of the colonies on plate-cultures. 2. Suspecting that this was concerned with light action, experiments showed that insolation not only kills off large numbers of the bacteria in the water, but in some cases shows...
Page 217 - ... Smith. The author described a method for preparing media suitable for the cultivation of bacteria. The principle of the method consists in the addition of a small percentage of alkali to fluids which contain proteid such as egg-white and serum of blood. The fluid is then heated to the boiling-point or over it in the autoclave. By this means it is converted into a clear transparent jelly. It is then a medium suitable for the growth of a large variety of germs. PARIS. Academy of Sciences, May 28....
