摘要:

During the year 1932, many difficult problems arose affecting the welfare of the British Institute of Radiology and its Journal. Attempts were made, with more or less success, to solve some of these problems; others remain to be dealt with, and it is hoped that satisfactory solutions will be arrived at in the near future.

摘要:

Mr. President, ladies and gentlemen: I need not say that no one here regrets more than I do that the Minister of Health, Sir Hilton Young, is unable, because of his Parliamentary duties to-day, to accept your invitation to open this Exhibition. You will agree with me that I am a very poor substitute for a Minister of the Crown, for I can only claim to have been the obedient servant of the Ministry for a great many years. I have come here, therefore, to represent the Minister, and also, if you will allow me to be so bold, to represent myself. I am here for two reasons. In the first place I had a pressing invitation from my friend and colleague, Dr. Stanley Melville, the Consulting Radiologist to the Ministry of Health; it is through him that I come to support this very admirable society, the British Institute of Radiology. But, also, I am here because I have for many years been keenly interested in the subject of radiology. It is a great pleasure to carry out the honourable task of opening your Exhibition.It has been said by some of the great leaders of science, including the President of the British Association, that our discoveries in science are so rapid and so fundamental that they have outstripped the capacity of the average man ever to appreciate or to apply them; and perhaps that truth, remarkable as I think it, has a definite application to the great subject, to the triumphs of which you and I are met here to bear witness.

摘要:

One of my predecessors in the alarmingly erudite succession of Silvanus Thompson lecturers commenced his paper as follows:—“For the privileged position I occupy to-night I can at least claimonequalification.”I am in a regrettably different position, for I can claim no qualification, unless it be the entirely vicarious one of having presided—as a layman—over the National Radium Commission for the past three and a half years,i.e., since its inception.

摘要:

The subject of my lecture, the neutron and its properties, has at present no professional applications for the radiologist, but it has some points of general interest apart from its mere novelty.The conception of a neutral particle is not new. It was suggested by Rutherford in 1920 that a proton and an electron might unite much more intimately than they are combined in the hydrogen atom and so form a particle of a new type, which would have peculiar and interesting properties. The suggestion was made partly because such a particle would be the first step in the formation of atomic nuclei from the two units, the proton and the electron, and partly also to make it possible to understand how complex nuclei can be gradually built up from simpler ones.Experiments were made in 1921 by the late Professor Glasson and by Roberts to detect the formation of such neutrons when an electric discharge was passed through hydrogen, but with negative results. The possibility that such a particle might exist was, nevertheless, not lost sight of. I myself made some experiments to detect them—in electrical discharges and in both radioactive and artificial disintegrations—but with no successThe first step towards the discovery of the neutron was given by the experiments of Mme. Joliot-Curie and M. Joliot, who were investigating the properties of a radiation emitted from beryllium when bombarded by α particles.

摘要:

Prof. Jellinek, of Vienna, whose work on electrical injuries and accidents is well known to engineers and practitioners of electrotherapy, has been awarded the Prix Barbier by the French Academy of Science. It was this distinguished worker who first established the fact that people who were regarded as dead after electric shock were really in a state of suspended animation and could be restored by artificial respiration. In consequence of this teaching countless lives have been saved.

摘要:

The Presidential Address by Prof. Hopwood was the terminal event of the scientific proceedings of the Congress, and was delivered before a large audience at the Central Hall, Westminster, on Friday afternoon, December 9. It was accompanied by lantern slides, and followed by a cinematograph demonstration.Prof. Hopwood said that every congress he had attended had organised some excursion for its members, and he proposed to take the audience on an excursion along the new arterial road which has been driven right through science and medicine, the road of radiation.[The President here showed the electro-magnetic spectrum, indicating the different classes of radiation, from the longest to the shortest waves.]He then showed examples of recent research in various fields of radiological interest, commencing with a record of experiments carried out by Prof. Bose in the Bose Institute at Calcutta. These experiments related to the effect of short wireless waves on the growing wheat plant. When a strong wireless signal was received by the plant, the plant showed a retardation in growth. Less strong signals showed a retardation of growth followed by growth stimulation, while weak signals were followed by stimulation only. There is a lag of two or three seconds between the transmission of the stimulus and the effect produced.

摘要:

(1) Fractures in the region of the neck of the femur are usually subdivided into the intra- and extra-capsular variety. This classification is faulty and misleading.(2) An analysis of the injuries, in the region examined in this series, shows them to be readily classifiable into five types. Although certain authors have attempted to subdivide the trochanteric variety into two, I am of the opinion that this is not practicable, since a large proportion are true neither to the intertrochanteric nor to the pertrochanteric type.(3) Since the great majority, at least, of the trochanteric fractures would, according to the older classification, have been called “extra-capsular,” and since it is stated that this type occurs generally in muscular adults and infrequently in old age, the large proportion found in this series directly contradicts the modern teaching.(4) It is submitted that even trochanteric (the so-called extra-capsular) fractures are not due to direct external violence in the aged. The suggested mechanism can be regarded as a compression action of the affected limb, resulting when the whole weight of the body is suddenly thrown upon it. The bone breaks in the vicinity of its angle (the region of the intertrochanteric line), and not through its weakest point, the neck.(5) The transcervical, and presumably also the subcapital fractures, are caused by an axial torsion of the cervix femoris.(6) In the trochanteric fractures there is usually impaction of the upper fragment into the lower. Sometimes, in addition, the great trochanter is comminuted, but more commonly the small trochanter, with or without a thin portion of the shaft, is chiselled off by the most inferior part of the upper fragment, which almost invariably has a sharp lower angle.(7) The subtrochanteric fracture is in reality a fracture of the shaft proper. It involves the inferior portion of the trochanter major. There appears to be no definite agreement about the trauma producing it.(8) “Avulsion fractures” of the trochanter major consist of the detachment of the tip of that prominence, presumably as a result of spasmodic muscular action.(9) The degree of shortening of the limb varies considerably in the first three varieties discussed, and it is no criterion, clinically, of the type which has occurred.(10) The fracture most frequent in the aged is that through the mass of the trochanter major, and X-ray examination alone reveals the nature and extent of the damage.

摘要:

The inaugural meeting of a local section of the Institue of Physics was held at Manchester on Friday, November 18 last. Twenty-eight members and visitors were present. This is the first local section to be formed in this country, but there have been in existence for some time local sections in Australia and India. Professor W. L. Bragg, F.Inst.P., F.R.S., was elected Chairman, and Dr. H. Lowery, F.Inst.P., Local Honorary Secretary; a provisional committee was appointed consisting of these officers and Mr. W. Jackson, A.Inst.P., Mr. F. Oldham, A.Inst.P., Mr. S. W. Redfearn, Dr. F. C. Toy, F.Inst.P., and Dr. R. S. Willows, F.Inst.P. During the course of the meeting many of those present expressed their opinions as to the directions in which the new local section would prove valuable and the general enthusiasm shown augurs well for its future success.
