valescent homes there were for the army and for other professions, but none for the sailors. That has now been changed, for this home will take seamen of the Imperial Navy or of the mercantile marine, as well as soldiers from the colonial or protectorate troops, to the number of 60, and also their officers to the number of 15. Retired and half-pay officers may be received if there is room. No serious cases requiring much attention can be received and no contagious diseases. The accommodation and recreation rooms for men and officers are quite separate ; there are smoking and writing rooms for each with all the foreign military and naval papers, and a good library. For their treatment there are douche, steam, and electrical baths, and even a small swimming-bath. There is central heating and electric light throughout. The association has provided the site and the house ; the medical treatment and maintenance are secured by a charge of 3s. 6d. daily for each man, 4s. 6d. daily for junior, 5s. 6d. for senior officers. The navy has taken ten beds, and it is hoped the large shipping firms will each similarly annex others.

A
HISTORY OF THE
CAVENDISH
LABORATORY.1
AFTER having successfully provided in the years 1864 and 1865 accommodation for the study of zoology, comparative anatomy, human anatomy, chemistry, mineralogy, and botany, the University of Cambridge turned its attention to the needs of the students who wanted instruction in heat, electricity, and magnetism. The prospect of expenses, however, very nearly defeated the good intentions of the syndicate which was formed to this end and which reported in favour of founding a special professorship and of supplying the professor with the means of making his teaching practical. It was not until October, 1870, that the opportunity came for making a real start with the Cavendish Laboratory. The Duke of Devonshire expressed a desire to carry out the recommendation of the syndicate, adding that he would be prepared to provide the funds required for the building and apparatus. 0 sing to a decision of the heads of the Colleges that the sums required under 1 A History of the Cavendish Laboratory, 1871-1910.

successively by three men of such great and such varied genius as Clerk-Maxwell, Rayleigh, and Th)mson, who have made the Cavendish Laboratory known throughout the world. The transactions of the learned societies record what valuable work has been done, and it is now most interesting to discover in the book referred to how that work came to be done, in a series of monographs contributed by competent writers like r. C. Fitzpatrick, Arthur Schuster, R. T. Glazebrook, H. F. bewail, E. Rutherford, C. T. Wilson, N. R. Campbell, L. R. Wilberforce, and the present professor himself. The history s a splendid record of scientific work and education.
DIPHTHERIA OF THE VULVA IN A CHILD.
DIPHTHERIA of the vulva or vagina is very rare, and has been observed in two conditions-in the puerperium and in children. In 1898 Whitridge Williams recorded the case off a woman who on the twelfth day of a normal puerperium began to complain of pain and swelling in the vulva. The inner surface of the labia majora and minora was covered by a greyish-white membrane which extended a short distance The diphtheria bacillus was found, and up the vagina. took recovery place under antitoxin. The infant and an elder child were subsequently attacked with diphtheria and died. In necropsies in cases of puerperal septicaemia dirtygreyish or yellowish membrane is frequently found in the uterus and vagina, and has been described in the older works as diphtheria, but is generally due to necrosis produced by the streptococcus or other organism. Very few cases of of vulva in the children have been recorded. It diphtheria or to be may primary secondary diphtheria of the throat. In the Nero York Medical Journal of Jan. 7th Captain L. L. Smith, of the Medical Corps of the United States Army, has reported the following case. On March 15th, 1910, he was called to a girl, aged three years, who was suffering from slight cough with a little pyrexia. The throat and nose were examined with negative result, and in a day have completely recovered. A or two she seemed to few days later he was again called to see the child, as attempts to micturate were unsuccessful and caused her to cry with pain. The meatus urinarius and labia minora were slightly inflamed and swollen. There was some mucoid vaginal discharge, but no membrane was seen. As hot applications to the vulva and lower abdomen failed to produce micturition a catheter was passed. The urine was
