during the corresponding periods, owing to the ease with which the effectiverays are absorbed. A second series of experiments designed to test the relative values of direct sunshine and of sky-shine " demonstrated that the scattered rays were from a half to two-thirds as effective as the direct sunshine, a point of practical importance as indicating a means of applying an efficient dose of ultra-violet rays in cases where radiant heat is undesirable. Animals exposed to light were not only protected from rickets, but also showed an increased resistance to deliberate infection, twice as many of the irradiated rats surviving an intraperitoneal injection of pathogenic bacteria as did controls kept in the dark. The intestinal contents of the irradiated rats were found to be more acid than those of the controls, indicating a better digestion in the former. Tests carried out with various special glasses transparent to ultra-violet rays convinced the writers that for glazing ordinary windows they were of little value, owing to the small amount of sky-shine that is available.

HARVEY TERCENTENARY. THE Royal College of Physicians of London is celebrating the tercentenary of Harvey’s great publication from May 14th-18th. We have already set outa provisional programme of arrangements, and we are asked to make it known that the College has reserved a proportion of tickets for such Members and Licentiates of the College as may wish to be present One hundred at certain parts of the celebrations. tickets are available for the conversazione at the Hall of the Merchant Taylors Company at 9 P.M. on Tuesday, May 15th ; each ticket-holder is invited to bring a lady with him. A similar reservation for Members and Licentiates, without ladies, has been i made for the banquet at the Guildhall at 7 P.M. on Wednesday, May 16th. There will be an inclusive’ charge of 2 guineas for each dinner ticket, which should be sent as soon as the applicant receives notice that a ticket has been allotted. Some tickets will also be allotted to Members and Licentiates for the I demonstrations in the Physiological Department of

IN THE EYE. A CASE which illustrates the need for care in using silver nitrate to prevent ophthalmia is recorded by Dr. J. G. F. Heal in a recent number of the British Journal of Ophthalmology. As the mother was believed to have gonorrhoea, the doctor ordered nitrate of silver in a strength of 1-5 per cent. to be dropped into each eye three times a day, and at least five instillations had been done before Dr. Heal was He found the child with conjunctival called in. haemorrhage and steamy cornea on both sides, and on one side the haemorrhage proved so persistent that on the fourth day the infant had to be put under chloroform so that the bleeding-points could be touched with a cautery.

KIENBOCK’S DISEASE. Dr. F. W. Van Valkenburg,l who records an illustrative case, defines this condition as a chronic slowly progressive type of osteitis of the semilunar bone. ’The following three forms have been described by W. Miiller, the classification being based on their aetiology : (1) an anatomical form due to abnormal pressure lines from anatomical abnormalities ; (2) an occupational form due to repeated minimal trauma ; and (3) a traumatic form due to a single violent injury. The patient’s first complaint is that of a lame wrist which may or may not have been preceded by a history of trauma. The disease does not usually become well developed until after the lapse of six or eight months, when examination reveals definite tenderness over the .semilunar bone, limitation of flexion, and extension of .the wrist, and localisation of pain over the semilunar bone on tapping the head of the third metacarpal with the fist closed and the hand in ulnar adduction. The head of the third metacarpal will also be found to be on the same level as those of the second and fourth, whereas normally it is more prominent. X ray examination at an early stage is usually negative, but after seven to nine months the semilunar bone appears whiter and more dense, and later still shows fragmentation and atrophy. Kienbock’s disease must be distinguished from tuberculosis, syphilis, and chronic arthritis of the wrist due to other causes. In the early stage conservative treatment in the form of immobilisation for one or two months with massage and electricity is indicated, but operation is required in long-standing cases and those in which conservative treatment has failed. In Dr. Van Valkenburg’s case, which occurred in a man aged 39, a cabinet-maker by occupation, the condition developed without any history of injury to the wrist. The Wassermann reaction in the blood was negative. In spite of a wrist support the joint became much more painful and in the course of a few months X rays showed the typical 1

MAXIMA CHARTA. Senator Copeland introduced into Congress last month a Bill which would give the same rights and privileges to the degree of doctor of osteopathy as to that of medicine. This information has to be set against other news from America, printed in another column, which suggests that chiropractic has suffered something of a set-back. According to the Journal of the American Medical Association the Copeland Bill is framed upon remarkably generous and comprehensive lines. It contains, for instance, a definition of drugless healing which is to cover " any system of healing that teaches that disease may be prevented, relieved, or cured without the use of drugs, medicine, or operative surgery." Any five or more adherents of any so-called drugless method of healing can present a petition (if the Bill should become law) demanding the appointment of an official and permanent board of examiners, and thereupon their particular cult will apparently be recognised as on an equal footing with the orthodox practice of medicine and surgery. The only limitation, we are told, upon the official recognition of any particular drugless cult is the requirement that the petitioners should somehow differentiate it from the unrestricted practice of the healing art. It is difficult to comment further upon Senator Copeland’s proposals without a study of their exact text; but it is understood that they include the licensing of osteopaths to practise surgery and to prescribe drugs, the issuing of licences with reciprocal effect, and the general authorisation of diagnosis and treatment either

What may perhaps be described as freak legislation is by no means confined to America, but for the present the sheet-anchor of the qualified medical practitioner in this country-namely, Section 32 of the Medical Act of 1858-looks like holding fast.
