This is a timely production, written by a man who appears to have sterling honesty as well as sterling sense, and devoted to a subject as interesting as any which can engage the attention of the community. We hope it will attract sufficient attention to insure its extensive circulation, and bring it within the notice of all families. The author grapples with his subject thoroughly, and almost exhausts it. Owing to the various forms, genteel and vulgar, which quackery has assumed in our day, no person, intelligent or ignorant, is safe from some one mode of its operation, as it has contrivances for every age, disposition, grade of mental development, and social station. Dr. Hooker has gone elaborately over the whole matter, and has really given the philosophy as well as the facts of empiricism, both as it exists out of the profession and in it. He does not spare those physicians who follow medicine as a trade, instead of pursuing it as a profession, “and study the science of patient-getting to the neglect of the science of patient curing,” while in showing the processes of the quack in experimenting on the credulity of his victims, he has done an essential service to the health of the community. We can but reiterate the hope that the volume, full as it is of practical wisdom, will be extensively circulated, and do its part toward enlightening the most quack-ridden people on the face of the earth. * * * * * _History of England from the Invasion of Julius Cæsar to the Abdication of James the Second.
