    First, on the circulation of the blood ; Secondly, on the structure and functions of the lungs ; Thirdly, on the atmospheric air; and then proceed, ■ Fourthly, to describe to you the method of using the Zapuron in eases of suspended animation. First, the circulation of the blood. In the process of circulation, the blood is conveyed from the left ventricle of the heart by the aorta, or great artery, and its branches, to the minutest and most remote parts of the body ; and there, passing from the extremities of the smallest arteries into the incipient veins, circulates through them into their larger branches ; afterwards into the right auricle ; and, in succession, to the right ventricle. It is, with the fresh supplies that it receives from the chyle passing into the subclavian vein, forced thence into the pulmonary artery, and, after circulating through the lungs in its passage, is returned by the pulmonary vein into the left auricle, and thence into the left ventricle of the heart. The same round recurs, and this is what is called the circulation of the blood. We next turn our attention to the lungs. The lungs are two spongy and vascular organs, of considerable size, situated in the lateral parts of the chest. Their parenchyma or substance is divided and subdivided into large and small lobes; the number, form, and dimensions of which are difficult to be explained. I An attentive examination of one of the pulmonary lobes shews that it is formed of a strong texture, the areolae, or small cavities of which, are so minute, that a strong convex lens is requisite to discern them distinctly. ! These areolae communicate with each other, and are enveloped by a thin coat of cellular tissue, whicli separates them from the lobes that are
