    ] 0] auricle, whence it flows in to the right ventricle; this also, when it is sufficiently distended, contracts upon its contents, and pro- pels the blood into the pulmonary artery, by which it is con- veyed to every part of the lungs. The pulmonary veins then receive it, and convey it to the left auricle, whence it is propel- led into the left ventricle, that it may again be distributed by the aorta, to every part of the body. The blood is thus continually circulating through the body; and this process may be considered as one of the most important actions that is performed in the animal machine. If it be stop- ped for a few seconds, all motion is suspended; and if it be prevented a longer time from going on, vitality is destroyed. The function of the lungs is of equal importance in the animal economy, and cannot be stopped even for a short time, without suspending, or totally destroying animation. Ancient phisiolo- gists had a very imperfect idea of the manner in which these or- gans so essentially contributed to the support of life: the mod- erns, however, have been more successful in their researches; they have discovered that the blood derives from the air, which is taken into the lungs, the most important properties, without which it would be a useless vapid mass totally inadequate to the purposes for which it was designed. If we examine the blood in the left ventricle of the heart, and in the arteries it will be found of a bright scarlet color, and replete with those prop- erties which render it capable of nourishing the body, and stim- ulating the whole system to action: in the veins it becomes of a much darker color; and when it arrives at the right ventricle is nearly black, and destitute of those enlivening qualities which it possessed in the left ventricle. Had not the Deity then pro- vided some means for its renovation, it would have been quite unfit for a second circulation, and the duration of life must have been short indeed; but from the right ventricle it is conveyed by the pulmonary artery of the lungs, at the moment they are distended with air: here the blood undergoes a wonderful alter- ation, it resumes its bright scarlet color, and is returned by the pulmonary veins to the left side of the heart, with all its original and essential qualities restored to it. It is proper to observe, that there are valves placed in such situations, as effectually pre- vent the blood from taking a retrograde course. Were it not for this contrivance, the blood would as readily be forced into the left auricle as into the great artery, when the left ventricle, which lies between them, contracts, or shrinks up; and so of the other parts. Hence we may learn how important are the functions of respi- ration and the circulation of blood, how essential to the life ©f animals, and how independent they are on each other.
