It seemed, with reason, to the editors of this series that room should be found in it for a work dealing with syphilis considered with reference to the army and the present war. The frequency of this infection in the army, among the workers in munition factories, and in the midst of the civil population where this is in contact with soldiers and mobilised workers, makes it, at the present time, a true epidemic disease, and one of the most widespread of epidemic diseases. Dr. Thibierge, whose previous labours guarantee his peculiar competence in these difficult and important questions, has, in writing this manual, very notably assisted in this work. But the treatment of syphilis has, during the last six years, undergone considerable modifications; the new methods are not yet very familiar to all physicians; and certain details may no longer be present to their minds. It was therefore opportune to survey the different methods of treatment, to specify their indications, and their occasionally difficult technique, which is always important if complications are to be avoided. It was necessary before all to state precisely and to retrace, for all those who have been unable to follow the recent progress of the therapeutics of venereal diseases, the characters and the diagnostic elements of the manifestations of syphilis. MALARIA IN MACEDONIA: Clinical and Hæmatological Features. Principles of Treatment. By P. Armand-Delille, P. Abrami, G. Paisseau and Henri Lemaire. Preface by Professor Lavern, Membre de l'Institut. Edited by Sir Ronald Ross, K.C.B., F.R.S., LL.D., D.Sc., Lieut.-Col. R.A.M.C. With illustrations and a coloured plate. Price 6/- net This work is based on the writers' observations on malaria in Macedonia during the present war in the French Army of the East. A special interest attaches to these observations, in that a considerable portion of their patients had never had any previous attack. The disease proved to be one of exceptional gravity, owing to the exceptionally large numbers of the Anopheles mosquitoes and the malignant nature of the parasite (Plasmodium falciparum). Fortunately an ample supply of quinine enabled the prophylactic and curative treatment to be better organised than in previous colonial campaigns, with the result that, though the incidence of malaria among the troops was high, the mortality was exceptionally low. Professor Laveran, who vouches for this book, states that it will be found to contain excellent clinical descriptions and judicious advice as to treatment. Chapters on parasitology and the laboratory diagnosis of malaria are included. An early announcement will be made in regard to further volumes under consideration. _The cost of postage per volume is: Inland 5d.; Abroad 8d._
