    culation; the other to distribute the blood, after having been thus renovated in the lungs, to the general system. Hence the former set, including veins, a sinus, an auricle, a ventricle, and arteries, are, in Dr. Barclay’s Nomenclature, denominated pulmonic, and the blood which they contain, and which is of a dark colour, is termed pulmonic blood. In the same manner, the latter set of organs, comprehending also veins, a sinus, an auricle, a ventricle, and ar- teries, are denominated systemic; and the florid blood which they contain, is termed systemic blood. It may be proper to remark, that the merit of this nomenclature consists, not in the novelty of the terms, but in the more precise and definite application of terms long in use among anatomists, but hitherto employed in a manner so vague and ambiguous, as to mis- lead the learner in Human Anatomy, and be almost wholly in- applicable to Comparative. As the terms are drawn from parts long known and described in anatomical works, a knowledge of those parts once acquired leads to the ready application and use of the terms. They are the more easy of apprehension to the anatomist, as being accommodated to an established custom among anatomi- cal writers, of describing the body and its parts as a cube or six- sided figure, whose surfaces point upwards, downwards, backwards, forwards, to the right and to the left; and whose parts are situated towards the circumference, the centre, or an imaginary plane, di- viding the body into similar halves. It is this imaginary plane which has furnished the only strictly new aspect in Dr. Barclay’s Nomenclature. The uses and advantages of many of these terms will be illus- trated by the notes to the following pages; but to render them more familiar, we shall here contrast them with the usual terms in the following Tabular Outline.
