Page 142 - NB, All the above exercises are to be sent in to the Vice-Chancellor privately ; each is to have some motto prefixed, and. to be accompanied by a paper sealed up, with the same motto on the outside ; which paper is to enclose another, folded up, having the candidate's name and college written within.
Page 142 - Name and College written within. The papers containing the Names of those Candidates who may not succeed will be destroyed unopened. Any Candidate is at liberty to send in his Exercise either written (but not in his own hand) or printed or lithographed.
Page 289 - 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 that the so-called raised beach is the undestroyed remnant of an extensive district of wind-borne sand similar to that which now exists on Braunton Burrows. The points to which attention was invited are as follows : — 1. Is this deposit on the southern slope of Saunton Down...
Page 144 - Committees for the several Sections before the beginning of the Meeting. It has therefore become necessary, in order to give an opportunity to the Committees of doing justice to the several communications, that each Author should prepare an Abstract of his Memoir, of a length suitable for insertion in the published Transactions of the Association, and...
Page 144 - If it should be inconvenient to the Author that his Paper should be read on any particular days, he is requested to send information thereof to the SECRETARIES in a separate note.
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 188 - 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.
Page 143 - Master and Senior Fellows of St John's College, at the request of the Senate, to propose for its adoption an amended Scheme.
Page 276 - The fact that the steady motion breaks down suddenly, shows that the fluid is in a state of instability for disturbances of the magnitude which cause it to break down. But the fact that in some conditions it will break down for a large disturbance, while it is stable for a smaller disturbance, shows that there is a certain residual stability, so long as the disturbances do not exceed a given amount....
Page 190 - This and (8) are two equations for the determination of v and p. Eliminating p between them, we find a single equation which, with proper initial and boundary conditions, determines the one unknown, v. When v is thus found, (8), (7), (9) determine p, u, and w. 30. An interesting and practically important case is presented by supposing one or both of the bounding planes to be kept oscillating in its own plane ; that is, F and § of (6) to be periodic functions of t.
