    nected with the descent of femoral hernia. For this purpose an incision is to be made from the neighbourhood of the anterior superior spinous process of the ilium inwards, in the line of the gi-oin, and carried half way down the inside of the thigh. The large flap of integument thus marked out is to be raised and tm-ned outwards. The subcutaneous fascia is then to be laid bare by the removal of fat, and it will be advantageous if this can be done in concert with the dissector of the abdomen. Various small superficial arteries and veins will be seen, viz.: the super- ficial epigastric, superficial circumflex iliac, and superior and infe- rior superficial pudic. The fascia lata will be laid bare, and the cribriform fascia overlying the saphenous opening. On the surface of the fascia lata will be brought into view the internal or long saphenous vein passing into the saphenous opening, frequently presenting two branches ; nearly in front of the femoral artery, the cmral branch of the genito-crural nerve; and internal to the anterior superior spine of the ilium, the external cutaneous nerve. A twig of the ilio-inguinal nerve may also be seen distributed to the skin of a small part of the thigh close to the pubis. The bor- der of the saphenous opening is to be made distinct by removing the cribriform fascia, and in doing this the superior cornu or falci- form process is to be shown with its attachment to the pubic por- tion of the fascia lata. This falciform process is then to be separ- ated from the fascia lata and turned to the outside sufficiently to expose the infundibuliform or crural sheath, investing the femoral vessels, and the dissector may examine the three compartments into which this sheath is divided, and which contain respectively the artery, the vein, and a lymphatic gland; the latter blocking up the crural aperture between the femoral vein and Gimbernat's licrament, through which femoral hernia descends. All the rela- tions of these parts are to be carefully studied with special reference to the operations for strangulated femoral* hernia. The incision on the inner side of the thigh is now to be pro- longed downwards towards the middle line beyond the knee, and the dissection of the front of the thigh continued. The two middle and the two internal cutaneous branches of the anterior crural nerve, together with the branch from the internal saphenous
