A SELECTION of books and manuscripts, to illustrate a series of lectures by Dr. Douglas Guthrie on the history of medicine, has been placed on view in the Upper Library Hall of the University of Edinburgh. Included among manuscripts of the thirteenth century are beautifully written copies of the “Breviarium Medicum” of Serapion, a Syrian physician of the ninth century, and of Avicenna's “Canon of Medicine”, a favourite text-book, by the “Prince of Arabian Physicians”, which retained its popularity for many centuries and is said to be used still by native practitioners in India. There is also a fifteenth century manuscript of the “Regimen of Health of Salerno”, the best-known work of that famous school of medicine. It contains a full-page illustration of a medieval physician and one of his patients. A modern manuscript of much interest, on loan from the Royal College of Surgeons of Edinburgh, is a volume of notes of lectures on surgery, delivered by Lister while he was at Glasgow, containing the first written account of his “antiseptic principle”. Among the printed books the greatest rarity is “Christianismi Restitutio”, published in 1553 by Michael Servetus, who suffered death by burning at the hands of Calvin. Although it is a theological work, it contains an account of the pulmonary circulation. Only two other copies of the book are known to exist. There are also on view first editions of “De Re Medicina” by Celsus, dated 1478 ; Vesalius' “Fabrica”, 1543; Harvey's “De Motu Cordis”, 1623 (from the library of Alexander Monro tertius) ; Willis's “Cerebri Anatome”, with illustrations by Sir Christopher Wren ; Jenner's “Inquiry into the Causes, etc., of Cowpox”, 1798; and of W. T. G. Morton's brochure on the use of ether as an anaesthetic, 1847. One of the show-cases contains a collection of illustrated herbals, and a catalogue, dated 1683, of the Physic Garden, Edinburgh, which occupied part of the present site of Waverley Station. The exhibition is remaining open, during library hours, until the end of June.
