A publisher who pays much regard to usefulness and economy in reprints has put forth _Buchan's Domestic Medicine_ for something less than a crown, with a supplementary "Cholera Morbus, its history, symptoms, mode of treatment, antidotes,&c." By the way, we have often thought Buchan's book like the Dead Sea: you cannot fall into the latter without some of its water incrusting on you, and you cannot read Buchan without feeling an ache. Its popularity is founded upon the hackneyed adage "the knowledge of a disease is half its cure." People will pore over its sea of calamities till they almost fall into the fire, or get scalded with the water from a kettle, and then turn to the Index, Scalds, page 326: perhaps this is a good plan to test the practical value of a book, as the surgeon scalded two fingers and plunged one into turpentine and the other into spirits of wine to test their respective services in case of a scald. Here too we may notice a cheap _Companion to the Family Medicine Chest,_ with an alphabetical arrangement of Medicines, their properties, and plain rules for taking them; with the Cholera, of course, as a rider, and cautions respecting suspended animation and poisons. The little shillingsworth is in its fifteenth edition, so that many thousand persons must have taken many million doses by its prescription, and in some cases become their own medicine chests, with this book as their companion. * * * * * HERBERT'S COUNTRY PARSON, &c.
