Page 131 - PRESIDENT, IN THE CHAIR, The following Communications were made to the Society : (1) On the Electric Discharge through rarefied gases without electrodes.
Page 229 - ... the hypothesis. On the other hand, if an essential part of the glow discharge is due to the breaking up of the molecules, we might expect mercury-vapor to present other and much simpler phenomena than other vapors. This is the case, for if mercury-vapor is sufficiently free from air, the electrical discharge through it shows no negative glow, no dark spaces, and no stratifications.
Page 321 - I is the moment of inertia of the body about the axis of rotation through the centre of inertia.
Page 84 - ... the form assumed by many salts in crystallizing is affected by the character of the solution. Thus alum, which from a solution in pure water always assumes the octahedral form, takes the cubic form when the solution has been neutralized with potash. To return to the cubic and dodecahedral cleavages. If we suppose the excursions of the parts of the molecule to be greater in one direction than in the others, the figure within which the molecule is comprised will be a prolate spheroid ; if less,...
Page 340 - The whole heat generated from first to last gives a supply of heat at the present rate of loss for 3560 million years. This amount of heat is certainly prodigious, and...
Page xx - On the Rotation impressed by Plates of Rock Crystal on the Planes of Polarization of the Rays of Light, as connected with certain peculiarities in its Crystallization : by JFW Herschel, Esq.
Page 170 - ... is sensibly perfect, and involves an acceleration of phase of half a wave-length. For smaller wave-lengths, corresponding to those of light waves, the circumstances of the reflexion are more complicated. We shall proceed on Maxwell's theory, which postulates the nonexistence of condensational effects : no other theory can make the velocity of propagation of waves of transverse displacement inversely proportional to the square root of the specific inductive capacity of the medium1. The first point...
Page xii - Rule 3. 3. One of the Secretaries shall have the care of the Readingroom; and his office shall be to procure and take care of the books, to see that the papers are filed, and the Room properly prepared for the reception of the Members ; to collect the bills, sign them, and send them to the Treasurer for payment. 4.

Page 216 - Sarasin noticed4 a species of Stilifer encysted on the rays of Linckia multiformis. Each shell was enveloped up to the apex, which just projected from a hole at the top of the cyst. The proboscis was long, and at its base was a kind of false mantle, which appeared to possess a pumping action. On the under side of the rays of the same starfish occurred a capuliform mollusc (Thyca...
