    they are placed in front of the lumbar vertebre, around the aorta and vena cava. ‘To these may be traced the lymphatics of the lower limb, as well as those which accompany several of the branches of the abdominal aorta. The efferent absorbent vessels which proceed from these glands progressively increase in size, while their number dimi- nishes, and at length they unite into afew trunks, which, with - those of the lacteals, form the origin of the thoracic duct. THE LYMPHATICS OF THE THORAX. The lymphatics of the thorax are divisible into two sets, viz. those derived from the walls, and those from the viscera of that cavity. The former are arranged in two distinct planes, one lying between the skin and the muscles, the other being deeply seated. The superficial lymphatics at the front of the chest run upon the great pectoral muscle, and for the most part are directed towards the axilla, where they enter the lym- phatic glands. Those upon the back lie on the trapezius and latissimus dorsi, and, inclining from various directions, also converge to the axilla, and end in the same series of glands as the lymphatics of the upper limb. ‘The deep absorbents at the fore part of the chest correspond, in their general distribu- tion, with the internal mammary artery: commencing in the muscles of the abdomen, they ascend between the fibres of the diaphragm at its attachment to the ensiform cartilage, and then continue behind the costal cartilages to the top of the thorax. In their course they receive branches from the anterior part of the intercostal spaces, and ultimately terminate on the left side in the thoracic duct, and on the opposite side in the right lymphatic duct. The deep lymphatics at the sides and back part of the chest follow the distribution of the aortic intercostal arteries: they receive absorbent vessels which come forwards, through the inter-transverse spaces, from the parts seated’in the vertebral grooves, and other vessels from each side which run along the intercostal spaces. AJ] these incline inwards to the spine, and terminate in the thoracic duct. The lymphatics of the lungs, like those of other organs, form two sets, one being superficial, the other deep-seated.
