With a desire to render this work more extensively useful, the author subjoins to the systematic name of every disease, its chief technical and vernacular synonyms; confining, however, the vernacular synonyms to the English, German, and French languages, the technical ones, principally to the Greek, Latin, and Arabic. In this department of research, his knowledge of the Oriental languages has enabled him to proceed with firm steps over regions into which but few of his predecessors in physiology have attempted to make even an entrance. But, besides this peculiarity, there is another, and a very prominent feature in Dr. Good's treatise, which, I understand, served more than every thing else to give it popularity.

"In order to afford relief to the dryness of technical definitions, and verbal criticism, the author has digested his notes into a running commentary, which he has endeavoured to render replete with interesting cases, valuable hints or remarks, and singular physiological facts, gleaned from a pretty extensive perusal of the most approved authorities, collective or individual, ancient or modern; occasionally interwoven with

similar illustrations, as they have occurred to the writer in his own private walk and intercourse of life."

This "running commentary," is printed with a small type, and occupies, on an average, more than half of the page. A copious nosological index at the end of the volume, greatly facilitates reference, and proportionally augments the utility of the whole.

STUDY OF MEDICINE.

The first edition of Dr. Good's "Study of Medicine" was published in 1822, in four thick 8vo. volumes. It presented a fairly proportioned complete picture of medical science, as it then existed. But, happily for the world, neither the healing art nor the theoretic considerations on which it so mainly depends, are stationary. They partake of the general intellectual impulsion of the present times: so that, while the principles experience extension and correction, the practical applications become, in consequence, more simple, powerful, and direct. Thus the exigencies of the profession, and the success of this work (so well calculated for their use) concurred in the production of a new edition in 1825; in which, by modifications in the substance in many places, and valuable supplementary matter in others, the progressive improvements have been duly recorded; the whole being now comprised in five volumes.* As the largest portion of

* In a letter addressed to Dr. Drake (bearing date December 11th, 1824,) Dr. Good gives the following account of the progress of the new edition, and of the improvements which he proposed it to exhibit.

"I am now hard at work in printing off my second edition,-two volumes at a time,--so that the whole will, I hope, be finished soon after the end of March. Having completed, however, the entire range of its

the new matter appertains to what in the former impression constituted the second volume, the author has effected his augmentations "by dividing this alone into two volumes, and adding a little to the paging of the next."

Dr. Good describes his object in this comprehensive work to be to unite those different branches of medical science, which, when carried to any considerable extent, have hitherto been treated separately by most writers, into a general system, such as may be contemplated in a single view, and pursued under a common study. The branches thus united, are, 1. PHYSIOLOGY, or the doctrine of the natural action of the living principle. 2. PATHOLOGY, or the doctrine of its morbid action. 3. NOSOLOGY, or the doctrine of the classification of diseases. 4. THERAPEUTICS, or the doctrine of their treatment and cure.

In the nosological arrangement, the author has made composition, I have nothing to do but to correct the press. But I have bestowed a good deal of additional labour upon it, to meet some of the hints that have been communicated to me. It will now form, as far as I think it should, a record of all the opinions and methods of the continent advanced in our own day; which has rendered it necessary for me to remodel the writing in some parts of most of the pages, as well as to wade through an immensity of trash, in pursuit of a little sterling matter: and, at the particular request of the Army Medical Board, and especially of the Director General, it will a little enlarge on a few of the diseases of warm climates, from documents of their own, which have not met the public eye. There are also other subjects which remain to be brought forward, and have either been started or have grown into importance since the first edition :as, Thomson's work on Varioloid Diseases, and the question it involves : Willan's speculations on the same subject, published posthumously: the destructive inflammation that occasionally takes place on dissecting with a punctured hand (Erythema anatomicum ;)-the singular emaciation or bloodlessness, described by some of the French writers (Marasmus Anhamia;) the Melanosis of Breschet and others; and the lateral curvature of the spine, or spinal muscles (Entasia Rhachybia.) Then there is an account to be given of Laennee's Stethoscope, &c.; how far Syphilis may be cured, or it ought to be attempted, without mercury; many of the new medicines lately imported from France, &c. You will hence perceive that I must have another volume."

slight alterations in the distribution of one or two of the diseases, as compared with his "System of Nosology;" to the first six classes of which, however, he adheres, on the whole, throughout these volumes. The first volume comprises, in 630 pages, the whole of Class I, and the two first orders of Class II.--Vol. II. in 662 pages, the remainder of Class II, and the two first orders of Class III.-Vol. III. in 518 pages, is devoted to the remaining orders, genera, and species of Class III. Vol. IV. in 688 pages, includes the whole of Class IV.-And Vol. V. in 738 pages, comprehends Classes V and VI.

The notes at the feet of the pages, consist principally of references to other works of celebrity, British and Foreign, on the same or connected topics; and the side margin of every page contains, in a smaller type, a brief running abstract of the contents of the several sentences on the page itself. Every distinct opening of pages, too, exhibits an abbreviated reference to the class, order, genus, species: thus conducing greatly to a ready consultation of the appropriate portion of the work to which a student may wish to turn. A copious index of double columns on 30 pages, containing a reference to any subject, as indicated by its Arabic, Greek, Latin, or English name, in addition to the other facilities just specified, gives to this work an advantage which few other modern treatises, on either the theory or practice of science, can boast of.

That an adequate judgment may be formed of the nature of Dr. Good's classification, in reference, not merely to its medical bearing, but to its technical elegance and logical precision, I shall extract from his introductory table all that relates to the first class.
