scholarly journals Further note on a luminous glow generated by electrostatic induction in an exhausted vessel made of silica

1. A glow-bulb rotating within a shallow cylindrical inductor made with a dome-shaped end (devised by my son, E. J. Jervis-Smith, R. F. A.), placed symmetrically, with respect to the axis of rotation of the glow-bulb, exhibited the glow and magnetic phenomena described in the former paper and exhibited at the Royal Society on May 13, 1908. Sir Oliver Lodge has kindly repeated some of my experiments with glass bulbs, as set forth in the former paper, and also surrounded by a ring-shaped inductor, and has produced the same effects.

The present paper deals with the results obtained in the investigation of the atomic structure of rutile and cassiterite by the X-ray spectrometer. A detailed account of the method has been given by Prof. Bragg and his son, W. L. Bragg, in a series of papers communicated to the Royal Society. It consists essentially in allowing a narrow beam of monochromatic X-rays—in this case the rhodium rays—to fall on the face of the crystals, mounted on a spectrometer table, the axis of rotation of which passes through the face of the crystal. The beam is “reflected” by the atom planes parallel to this face, and thence passes into an ionisation chamber, containing methyl bromide in order to increase the ionisation current. The setting of crystal and chamber with regard to the incident beam corresponds to that for which ordinary light is reflected.

My dear Sir, The similarity of the laws of electrical and magnetic attraction has often impressed philosophers; and many years ago, in the progress of the discoveries made with the voltaic pile, some enquirers (particularly M. Ritter,) attempted to establish the existence of an identity or intimate relation between these two powers; but their views being generally obscure, or their experiments inaccurate, they were neglected: the chemical and electrical phenomena exhibited by the wonderful combination of Volta, at that time almost entirely absorbed the attention of scientific men; and the discovery of the fact of the true connection between electricity and magnetism, seems to have been reserved for M. Oersted, and for the present year. This discovery, from its importance and unexpected nature, cannot fail to awaken a strong interest in the scientific world; and it opens a new field of enquiry, into which many experimenters will undoubtedly enter: and where there are so many objects of research obvious, it is scarcely possible that similar facts should not be observed by different persons. The progress of science is, however, always promoted by a speedy publication of experiments; hence, though it is probable that the phenomena which I have observed may have been discovered before, or at the same time in other parts of Europe, yet I shall not hesitate to communicate them to you, and through you to the Royal Society.

In his long and distinguished career which bridged two centuries, Sir Oliver Lodge (1851–1940) was one of the most versatile intellectual figures in England. His discoveries in physics placed him in the first rank of British science. For his work in electricity, radio, and wave theory Lodge was awarded the Rumford and Alfred medals by the Royal Society. He also was a Romanes Lecturer at Oxford, a president of the British Association for the Advancement of Science, and the first Principal of the University of Birmingham. Lodge's publication record is breathtaking: more than 1,200 items, including nearly forty books, over a sixty-year period. While more than half of these were purely scientific or technical, it is significant that more than 100 pieces dealt with psychical research and an additional 170 books and articles dealt with topics in philosophy and religion. More than half of Lodge's writings in this latter category appeared between 1896 and 1914.

In the “Proceedings of the Royal Society,” 14th March, 1878, p. 179, Mr. George H. Darwin has published a criticism on ray proposed method of finding a limit to the duration of certain geological periods, published in the “Proceedings of the Royal Society,” 20th December, 1877, p. 534. My paper, of 20th December, consisted of two parts:—1st. A dis­cussion of the rate at which a “wabble ” of the earth’s axis of rotation caused by a want of coincidence between the axis of figure and the axis of rotation, would be destroyed by the friction of the ocean against its bed. 2nd. Speculative inferences from the solution of this problem, as to the duration of geological periods, depending on hypo­thetical geological assumptions as to the method in which Europasia was manufactured.


During the course of the magnetic re-survey of the British Isles, recently carried out by Mr. G. W. Walker under the auspices of the Royal Society, it was found that Melton Mowbray, Leicestershire, was a centre of pronounced magnetic disturbance, both vertical and horizontal. This result was in conformity with that obtained by Rucker and Thorpe in their surveys carried out 29 and 24 years earlier. So far as is known the only element that gives rise to magnetic phenomena on a large scale is iron. It appeared probable, therefore, that the local disturbances were to be connected with the distribution of iron in the rocks, and accordingly the origins of such disturbances were likely to be intimately related to the geological structure of the district.

In 1921 Oliver Lodge defended Philosophical Magazine against charges of mismanagement from the National Union of Scientific Workers. They alleged that its editors performed little editorial work, the bulk being done by the publishers, Taylor & Francis. Lodge reassured Nature's readers that the journal did consult its editors, and suggested ‘a conservative attitude towards old-established organs is wise; and that it is possible to over-organise things into lifelessness.’ The paper explores Lodge's response by considering the editorial arrangements at Philosophical Magazine . Founded in 1798, it remained remarkably unchanged and so appeared old-fashioned when compared with its closest rivals, Proceedings of the Royal Society and Proceedings of the Physical Society . We argue that for Lodge the management of Philosophical Magazine gave it the flexibility and independence required to sustain the kind of physics, also open to accusations of obsolescence, in which he believed.

In a paper recently read before the Royal Society, Professor Haughton has endeavoured by an ingenious line of argument to give an estimate of the time which may have elapsed in the geological history of the earth. The results attained by him are, if generally accepted, of the very greatest interest to geologists, and on that account his method merits a rigorous examination. The object, therefore, of the present note is to criticise the applicability of his results to the case of the earth; and I conceive that my principal criticism is either incorrect, and will meet its just fate of refutation, or else is destructive of the estimate of geological time. Professor Haughton’s argument may be summarised as follows:— The impulsive elevation of a continent would produce a sudden displacement of the earth’s principal axis of greatest moment of inertia. Immediately after the earthquake, the axis of rotation being no longer coincident with the principal axis, will, according to dynamical principles, begin describing a cone round the principal axis, and the complete circle of the cone will be described in about 306 days. Now, the ocean not being rigidly connected with the nucleus, a 306-day tide will be established, which by its friction with the ocean bed will tend to diminish the angle of the cone described by the instantaneous axis round the principal axis: in other words, the “wabble” set up by the earthquake will gradually die away.

The author commences this paper by taking a retrospective view of the principal facts which have been established regarding the magnetic disturb­ances, considered as a distinct branch of the magnetic phenomena of the globe, from the time when they were first made the objects of systematic investigation by associations formed for that express purpose, at Berlin in 1828 and at Göttingen in 1834, and dwelling more particularly on the results subsequently obtained by the more complete and extended researches instituted in 1840 by the British Government on the joint recommendation of the Royal Society and of the British Association for the Advancement of Science.
