(After Ulascagni.) a, Saphena major vein. 6, Inguinal glands. c, Commencing branches. <i, e,f,g. The continuations of the vessels simi- larly marked in the former wood-cut. At least two lymphatics, which are united frequently by short branches crossing from one to the other, accompany eacli of these arteries, and all are ultimately conducted by the blood- vessels to the popliteal glands, in which they terminate. The vasa efferentia of these glands, from two to six in number, entwine around the popliteal and femoral vessels, having frequent communications with each other by short cross brandies, until they reach the inguinal region, where they terminate for the most part in the deep-seated cluster of inguinal glands; one or more, however, may reach the superficial glands or even those accompanying the external iliac artery above Poupart's ligament. The deep- seated lymphatics in their course are joined by branches which have accompanied the principal ramifications of the bloodvessels ; they also at various points form communications with the superficial lymphatic vessels. The superficial lymphatics of the lower extre- mities may be divided into two groups; one con- sisting of numerous vessels which follow more or less the course of the saphena major vein and terminate in the inguinal glands; the other com- posed of but few vessels, which, accompanying- the saphena minor vein, join the popliteal glands. The latter take origin from the dorsal surface of the little toe and from the outer edge of the dorsum and sole of the foot; they proceed with the branches of the saphena minor vein in the direction of the external malleolus, from thence to the outer edge of the tendo Achillis, where they glide with the vein under the fascia of the leg to reach the centre of the gastrocnemms muscle, between the head
