A Catalogue of Sixteenth Century Printed Books in the National Library of Medicine

many that the same type of pot was, and is still, in use in the paint and colour industry. A final miscellaneous group embraces bleeding bowls. Not all those objects sold as bleeding bowls by antique dealers have held blood though coming within the author's description as 'single-handed'. Those graduated in fluid ounces are without doubt the real thing: it might be prudent to consider all others suspect unless there is a satisfactory origin or provenance for them as bleeding bowls: they would have to hold at least four to five ounces. Curiously, the barbers' bowls, at least those with only a small indentation in the rim, seem more suitable for such a purpose than to be fitted to the neck when being sbaved. Still under the heading 'Miscellaneous', the reader will find himself consulting notes on such diverse items as inhalers-now to be found on most second-hand stalls-and phrenological heads. Those patented by Fowler of Ludgate Circus, London, had as long a life as any. It is a heartening statement in the Foreword by the Director of the Institute that a further volume will deal with other ceramic material. We may hope that there will be further volumes that in time will cover the greater part of the vast Wellcome Collections. John Crellin has set a high standard by this first catalogue. Not only will students of the history of medicine and the allied sciences benefit by it but 'pottery people' everywhere will need the book and the collecting public will have a good part of their insatiable appetite slaked by the perusal of this well-produced and scholarly volume.
