The physiology of the circulation in plants : in the lower animals, and in man : being a course of lectures delivered at surgeons' hall to the president, fellows, etc of the Royal college of surgeons of Edinburgh, in the summer of 1872 . eep,cat. rabbit, etc. For descriptions of the dissections, vide Gold-Medal InauguralDissertation On the Ganglia and Nerves of the Heart, deposited in theLibrarv of the University of Edinburgh in 1861. 2 K 246 DU J. BKLL PETTIGREW ON THE Secondly, That situated on the pulmonary artery (a), and betweenthat vessel and the left auricle (d), composed of branches from thefirst dorsal ganglion of the left side, left pneuinogastric, and leftrecurrent laryngeal. Thirdly, That formed on the coronary sinus (Fig. 147, j, r),composed almost exclusively of branches from the second and thirddorsal ganglia of the sympathetic of the left side. The aorticplexus supplies branches to that surface of the right auricle(Fig. 146, c) directed towards the aorta, and likewise to the rightventricle (e) and right coronary vessels (Fig. 149, h). These plexuses,as well as the distribution of the nerves on the anterior and pos-terior surfaces of the heart generally, are seen at Figs. 146 and147. Fig. 146.
