Page 623 - A is a piece of brass rod with a hole bored through it through which the cathode rays pass on their way to the target B, a copper plate which is at the end of and in metallic communication with a cylinder of wire gauze. The variation in the speed of the cathode
Page 159 - Porcupine in 1868 during the survey of the North Atlantic. The microscopic study of these specimens shows that in B,ockall there exist rocks of exceptional interest, which are not represented in our islands, but have analogues in the Christiania district of Norway, where they have been so well studied by Prof. WC
Page 510 - “The amplitude, as we shall see presently, remains the same, and the increase of energy density is due solely to the fact that more waves are present in unit length of the train after the compression than
Page 783 - fact that the limiting value of the cathode deposit for actinium is higher than that for radium is exactly what would be expected when we consider that the recoil atom from actinium A is expelled with a greater velocity than that from radium A. Moreover, since the recoil deposit atom of thorium has a velocity
Page 769 - was produced by means of an ordinary waterblower. This gave the desired high velocities of the air current, which could not be conveniently obtained by means of a Mariotte's bottle or a gasometer. In order to obtain constancy of flow three regulators were installed in the system : a waterpressure regulator, in series with the
Page 159 - obtained a fragment from this rock, which later found its way into the collection of the Geological Society. More than 30 years afterwards, the specimen was recognized; it was then mislaid for another 30 years, and in 1895 was brought to me by the late Prof. T. Rupert Jones. ‘ He not only carefully studied all the literature connected with
Page 158 - it has a circumference of only 100 yards and a height of 70 feet, and, except in the very calmest weather, is quite inaccessible. It is the haunt of seabirds and, with its whitened top, resembles a sailing ship, for which it has often been mistaken. The rock rises from a bank (the ‘¿Rockall Bank ‘) upon which there are
Page 771 - springbrass clip slipped over the brass rod to connect the central electrode with the electrometer system. E is a guard tube, which is always kept earthed to prevent any leakage over the surface of the insulators. F is a brass ring which was employed in order to remove the ebonite plug P and
Page 427 - amount of emanation decays beyond a certain value. In Table I. the amount of charged gas activity is approximately proportional to the quantity of emanation in the vessel as measured by the saturation current (cf. 2, 16, and 19). If in Table II. we calculate the ratio of the gas activity obtained with
Page 781 - difference in this particular phenomenon may be more strikingly shown by considering the curves of ionization and activity corresponding to an infinitesimal amount of emanation in the vessel. These were obtained by the method used by Wellisch for the case of radium by producing the curves of fig. 2 and of the corresponding
