“THE USE OF TRACER ELEMENTS IN BIOLOGY”

and Therapeutics", by (Gias.), F.R.S. (EdiIi.); Hilton and Company and x 5!", pp. 875, with 43 of staphylococcal septiceemla, of the operation of vagotomy, of the therapeutic indications for aureomycin; but he would have heard that visceroptosis is still an acceptable diagnosis, that faradism is sometimes beneficial in constipation, that cholecystography is always dependable, and that the most the physician can do for peripheral arterial embolism is careful observation. In a work covering the whole field of medicine, it is not difficult to find points for criticism-much easier now than it was in Osler's day. But let it be therefore said at once that "Chamberlain" is a good medical primer, covering a surprisingly large field, printed on good paper, with an excellent series of coloured plates and illustrations. The reproductions of X-ray films are particularly satisfactory. The sections on blood disease, on the nervous system and on tropical diseases are perhaps the best. Within its province, and for undergraduate purposes, it succeeds very well, and can be commended to those whose responsibility it is to introduce students to the principles and practice of medicine. The illustrations alone make it a worthwhile possession at a surprisingly low price for today.
