Wayfarers in Medicine

confuLsing, especially since little atteml)t is made to give the old terms, which might have been done by putting them in brackets after the newv ones. If the student confines himself to this teaching no doubt it will be easy enough to understand, but one feels that he will be greatly confused if he tries to correlate P'rofessor Percival's terminology with that most commonly taught outside Edinbur-gh. In a book such as the Atlas mentioned above, unorthodox teaching is acceptable because here the text is of less importance than the illustrations and the Atlas is intended for post-graduate students to use in conjunction with larger textbooks. There are other controversial points in the book, perhaps of less importance. Erythema induratum is described as the commonest form of sarcoid. Ther-e are very fewv who wvill agree with this statement unless one is prepared to alter the definition of the word "sarcoid." The section on ringworm is not good: one feels that here the author hals over-condensed the subject so that much of it is liable to lead to confusion. On page 197 it is stated: "The microsporon is a purely human type and does not affect animals." One feels that this is far too broad a generalisation, liable to lead the student into difficulty when he hears of the microsopron canis, etc. On the other hand, the chapter on acne is uindouLbte(dly very good and full of souLnd reasoning and the slhorter pIarts on prognosis and tr-eatment in general at the beginning of the book are really excellent. There are a fewv misprints: vitamin regains its long lost "e" on pages 173 and 176, "consititute" appears on page 288 and "fibron tissue" under fig. 226. The word "tubercular" is used repeatedly, rather than "tuberculous," and the term "cheiropompholyx" should not, strictly speaking, be applied to the feet. No doubt these little slips will not appear in future editions and it is to be hoped that the author will add another few pages and make clear some of the points mentioned above. IThe book would be of very much greater teaching value, outside Edinburgh, if this wxere done. In conclusion it may be said that this book is beautifully produced in a non-austerity fashion by the publishers and one feels that despite its unorthodox teaching it will be as much a success as previous editions.
