The appearance of the eleventh edition of a work ought to be sufficient evidence of its popularity. This book has been before the medical public for many years. There is no other exactly like it in its combination of worldly wisdom and ethical advice. Numerous quotations interpolated in the book remind one of the Latin quotations in old Burton's "Anatomy of Melancholia," but they are so funnily chopped up and sawed off in some cases that the impression is somewhat different. We do not consider them a valuable addition.
