THE BRITISH JOURNAL OF SURGERY.

Up to the present no attempt has been made to issue inthis country a journal exclusively devoted to surgery, thoughin several other countries surgical journals of one kind oranother have existed for some years. At last Messrs. John

Wright, of Bristol, have decided to bring out the BritishJoecrnal of S1trgery. A very strong editorial committee hasbeen formed, including some of the best-known names insurgery in the British Isles, and Mr. E. W. Hey Groves is to

act as editorial secretary. We welcome the appearance ofthe first number; it consists of 152 pages, it is quartoform, and it is well printed on good paper. So muchfor the appearance of the journal. As to its contentsan equally favourable verdict may be given ; it containsa number of valuable papers, every one of which is

of great interest, and where needed illustrations have

freely been provided. A short introduction from the Pre-sident of the Royal College of Surgeons of England, SirRickman Godlee. sets forth the aim of those who are e

responsible for the new venture, and this is followed by avery good photogravure of Lord Lister, with a brief apprecia-tion of his work for British surgery. Dr. David Newmanhas written a paper on Renal Varix and Hypersemiaas Causes of Symptomless Renal Hasmaturia, illustrated withseveral coloured drawings. Mr. D’Arcy Power has a paperin which he urges the need for earlier operations in cases ofgall-stones; the paper is based on 90 cases, and we must

subscribe to the conclusions at which he arrives. Mr. Albert

Carless describes a case of a boy who had two dermoid cystsin the mid-line of the perineum. The two cysts communi-cated, and from the hinder of the two swellings there ranbackwards a narrow, hollow channel as far as the anal

margin. The two photographs show the condition very
