Page 265 - I was examining the condition of the wire in a darkened room, when a new and unexpected change revealed itself. During the cooling of the wire it was found that just as it reached a very dull red heat, a sudden accession of temperature occurred, so that it glowed once more with a bright red heat. Illuminating the index and scale of the apparatus, which was watched by an assistant, it was at once found that the reheating of the wire occurred simultaneously with the momentary elongation.

It seems probable, almost certain indeed, that analysis similar to that of § § 38 and 39 will demonstrate that the steady motion is stable for any viscosity, however small ; and that the practical unsteadiness pointed out by Stokes forty-four years ago, and so admirably investigated experimentally five or six years ago by Osborne Reynolds, is to be explained by limits of stability becoming narrower and narrower the smaller is the viscosity.

M'Kenny Hughes, MA, FGS The Author observes that amongst the raised beaches of SW England we generally find included the sand cliffs of Saunton Down and Middleborough on the coast west of Barnstaple. These deposits possess a further interest owing to the occurrence at their base of large boulders. In 1866 Mr. Spence Bate, in opposition to the prevailing view, concluded...
Page 449 - The difficulties in this apparently sufficient explanation were overlooked until after an explanation on the undulatory theory of light was proposed. This new explanation was at first almost as simple as the former. But it failed to account for the fact proved by experiment that the aberration was unchanged when observations were made with a telescope filled with water. For if the tangent of the angle of aberration is the ratio of the velocity of the earth to the velocity of light, then, since the...
Page 284 - But of such glacial epochs there was no valid evidence. Another inference from Dr. Croll's theories, that each glacial epoch consisted of a succession of alternating cold and warm or interglacial phases was also questioned, such alternations as had been indicated having probably been due to changes in the distribution of land and water, not to cosmical causes. The time requisite for such interglacial periods as were supported by geological evidence was more probably hundreds than thousands of years....
Page 221 - ... The author concluded that wherever we can fix the top or base of the London Clay, we get a northerly dip of 2£° to 3°, showing a fairly constant thickness of from 330 to 340 feet The same thing occurs from Odiham on the west to Ash on the east, whilst at Brookwood the London Clay is thicker. He also assumed the existence of a passage from the London Clay up into the Bagshot beds in the deep wells or borings at Wellington College, at Brookwood, and at South Camp. Hence at these points there...
Page 254 - Mutter." to become sensibly greater, the position of the light on the scale was noted and the action of the steam stopped. The annular space was now filled with cold water, and in about ten minutes afterwards the position of the light on the scale was again noted. The difference between the two readings was a measure of the amount of temporary twist or untwist produced by the change of temperature, the last being, on the average, 85° C. In several cases the heating and cooling were repeated with...
