Conversely they believe that changes in the opposite direction in any of the above factors in the blood count are favourable. Their observations upon pneumonia comrr,se 131 blood counts upon 40 cases, almost all of which were cases of lobar pneumonia, though a few examples of broncho-pneumonia were included. They findi, that leucocytosis occurs as frequently in fatal cases as in those which recover, and that this leucocytosis is due to an increase in the neutrophiles. When this increase in neutrophiles is excessive a very severe infection is indicated. Arneth’s differential count shows a constant shifting to the left in pneumonia, but appears to bear no relation to the clinical course of the disease. These results in pneumonia are somewhat in opposition to those of the earlier observers and require confirmation. Dr. Muller and Miss Reed’s paper is a useful study of an interesting question, and contains numerous references to the literature of the subject.

AN AUTUMN VACATION
COURSE
IN
PARIS.
IT is officially announced by the Faculty of Medicine of the University of Paris that a vacation course on clinical practice and the application of laboratory methods to clinical diagnosis will be given at the Medical Clinic of the Hotel. Dieu under the direction of Professor A. Gilbert, commencing The course will comprise 28 lessons, and on Sept. 23rd. will occupy 14 days, a morning and an afternoon class being held daily. The students will receive individual instruction in the examination of patients, prescription writing, the management of apparatus, and laboratory methods, and will be allowed to take away the preparations made by them. With Professor Gilbert are associated in the course Dr. Herscher, Dr. Lippmann, Dr. Jomier, and Dr. Maurice Villaret, of the clinical department; Dr. Paul Descomps, of the department of pathological anatomy ; M. Deval, head of the chemical laboratory ; and in the specialties, Dr. Guilleminot, Dr. Durey, and Dr. Dausset. A certificate will be given at the completion of the course, which is open to foreign medical men. The fees are 100 francs, which should be sent by Post-office order to M. Deval, Chef de Laboratoire, Hôtel-Dieu, Paris.

In a recent careful study in comparative anatomy Gordon Wilson, of Chicago, has shown that the tonsil secretes The r6le of the tonsils as or excretes into the pharynx. of infection Professor Mackenzie considers greatly portals exaggerated. He admits that they are so in certain cases, but to a less extent than the more abundant and receptive lymphatic structures of the nose and naso-pharynx. The tonsils are frequently held responsible for the results of morbid conditions situated elsewhere. If obstruction to to due adenoids be tonsils will often the removed, respiration take care of themselves. Even if they remain large and are causing no trouble they may be safely left, and as growth of the child proceeds they will become less conspicuous. The mere size of the tonsil Professor Mackenzie considers no indication for removal. A large tonsil does not necessarily mean a diseased one, nor does a small one mean a That the tonsil has one. some healthy important function is shown by its frequent growth after enucleation. Another point is that the tonsils play an important part in the mechanism of speech and song. They influence the action of the surrounding muscles On the other and modify the resonance of the mouth. hand, they may be so enlarged as to cripple both these functions, and then should certainly be removed. The changes in anatomical relations produced by tonsillectomy cannot be foretold, no matter how skilfully the operation is performed. The adhesions and contractions which sometimes follow, even in the best of hands, often ruin the singing voice. Professor Mackenzie shows that he would long hesitate before advising the operation in a great singer, or one depending on the voice for a livelihood. He considers that tonsillectomy is a dangerous operation which should be done only in a hospital or other place where there is every facility to meet the gravest emergency. It should be done only by a surgeon skilled in its performance, thoroughly equipped for every accident, and fully alive to the fatalities which have sometimes followed. He does not decry the many excellent measures which modern ingenuity has devised for operation on the tonsil when there are definite reasons for their application. -
