To have retained so many useless synonyms may, perhaps, require an apology. In fact, they were found in the pages of the work last mentioned, and had been introduced before its glaring defects showed that it was an unfaithful guide. Many could not be traced to an adequate authority; but it would have been improper to have rejected what others might, perhaps, find useful, and for which there might have been authorities, though we had not discovered them. Numerous, however, as they seem, more have been rejected than retained.

The references may appear, also, unreasonably numerous, and almost ostentatiously confined to foreign authors. The medical writings of our own country have not, however, been neglected; but these are, in general, within the reach of every practitioner: these only are pillaged, in every modern dictionary, while of many authors of credit the names are often unknown. We have too fastidiously arrogated exclusive merit to ourselves, and it appeared proper to point out the valuable observations of Senac, of Quarin, of Stoll, De Haen, Colin, Sarcone, etc. as well as of many Swedish and Danish physicians. Even Morgagni, as we have said, has been, of late, neglected. To lessen the extent, the Roman numbers relate to the larger portions of the work referred to - the Arabic numerals to the lesser.

In the Curae Posteriores many additions have been made, some of which, in the progress, had escaped attention, and others were designedly omitted, lest they might render the volumes too bulky. Various observations had also occurred in different publications and different collections since the articles were printed, and it was the author's ambition to render the work complete to the moment of publication. Somewhat may still have escaped him; but those who feel inclined to censure omissions, should look with candour on what has been done. The additions are referred to some convenient portion of the article; but they do not relate exclusively to that part, and are generally to be considered as a commentary on the whole, to avoid breaking them into too many detached parts.

To point out what is new, in these volumes, would be a tedious task: almost every article, at least every article of importance, may be styled original, scarcely in any instance copied from former authors, and usually connected with the collateral subjects. As already observed, it was designed to render the work one consistent whole, and the general principles will be found to pervade every portion; nor are the doctrines which limited the distinction of Con-oussio, forgotten under the article Ulcus.

Of the plates we shall add only a short account. The subjects have been chosen with great care; but the objects of the choice we must now explain. It is not necessary to say why the different views of the skeleton have been selected: these have always formed a portion of similar representations; and, as the basis of the whole, are highly necessary. The ligaments have been imperfectly represented, in every English publication, and the value of the present work is greatly enhanced by the elegant and accurate views of these connecting substances, from the superb volume of Caldani.

Views of the muscles have usually followed; but would have required many plates, without an adequate advantage. In the general practice of physic and surgery little could be gained by such representations, and we have already remarked, that it is impossible to teach the minutiae of anatomy by verbal instruction or engraved copies. If the osteology is well understood, descriptions will convey ideas sufficiently accurate for general purposes.

The course of the larger arteries is of more importance, and these have been represented, with care, from the works of Haller, not separately, but as related to the adjoining parts; and they recur in different plates, which contain the lymphatics and the vicera. The volumes of Mr. Hewson, and Mr. Cruickshanks, and the elegant engravings of Mascagni, have supplied the lymphatics: Loder, Haller, and Sandifort, the internal viscera. As the situation of these is often of considerable importance, in ascertaining the seat of a complaint, they have been represented in every view, and with great care, as the English works have been unusually deficient in this part.

The separate portions have been also supplied from the best anatomists. The elegant plates of Soemering have furnished representations of the eye: Mr. C. Bell's Anatomy those of the ear. We could not find a more accurate view of the stomach than in Cowper; and on again examining it, we perceive the constriction, mentioned by Mr. Home, as dividing the cardiac from the pyloric portions. Mr. Cooper has also supplied a good representation of the unimpregnated uterus, and its appendages; while, for the gravid uterus, and the natural situation of the foetus in utero, we have been indebted to the classical work of Dr. W. Hunter. Some other detached parts of less importance are represented in the plates of the arteries and the lymphatics.

A view of the brain has been supplied by Loder; and, when we reflected that, in very few circumstances, the course of the different nerves, in their progress, was of importance, and that, in these, the minute accuracy, acquired only by dissection, was requisite, we avoided enhancing the price of our work, by plates not generally useful. The surgical instruments represented are those most commonly employed, in the more improved practice of the art.
