    heart of any one of the larger animals. Figures 4 and 5 are ac- curate sketches from preparations in the Museum of St. Bar- tholomew's Hospital, exhibiting vertical sections of the anterior aortic and pulmonary valves of the ox. Any doubt as to the nature of this disposition of parts in the human heart, is at once removed by an examination of the same parts on a larger scale. This arrangement appears of importance when viewed in connexion with the functions of the valves. Dr. Reid* describes the reflux as sustained in part by the festooned rings at the base of the valves, but in fact they are thinnest at this very part, correspond- ing to the central portion of the convexity of the valve; and if the description previously given of the formation of the tendinous festooned rings be a correct one, it is obvious why it is so—the thicker portions being the projecting angles, at the junction of two valves, to which points the tendinous fibres of the valves converge. Probably this arrangement will be better understood from the accompanying sketches than from any lengthened verbid description. Now, inasmuch as the posterior portion of the aortic orifice is continuous with the left auriculo-ventrioular ring, no
