it is familiar as a household word. The British medical man who does not know this book must indeed be a rara avis; its only fault is its size, for it is not a book one can conveniently carry about for ready reference, and its companionship is therefore restricted to the study and the consulting room. The nineteenth edition records advances in medical and pharmaceutical sciences almost up to the early summer of this year, which is saying a great deal, for anyone who has had anything to do with

... the preparation of a large volume of this nature, and one which must have a great circulation, can appreciate the difficulties in the way of keeping the matter quite up to date from p. 1 to p. 1712.

The medical portion of the book has been revised by Dr. Taylor Grant, and the notes on the medicinal properties of the drugs are really concentrated accounts of all that is worth knowing-for practical purposes-of the drugs in question. To prescribers these notes are very valuable, and hardly less useful are the prescribing notes which represent Mr. Squire's personal experience of over 40 years in the dispensing of prescriptions. Perhaps it is that pharmacists are rather shy about making suggestions to medical men, but authors of books of this class are not over-generous in their prescribing hints. And so we make the suggestion to Mr.
