    the anteriw cutaneous branches of four or more loiver thoracic nerves [524] with corresponding vessels [446] in company, are to be preserved and followed out from their emergence in an outer and inner series through the sheath of the rectus muscle. Further out will be found the linea semilunaris indicating the outer margin of that sheath, and external to this the aponeurosis of the obliquus externus muscle continued, towards the side of the abdomen, into its muscular fibres, which are directed outwards and upwards [376]. As the reflection of the fascia from the surface of those fibres is continued, there will be found emerging from between them, along the side, the lateral cutaneous branches [524] of the lower inter- costal nerves; and these, being at once pursued to their distribution, will be found each to divide into an anterior and posterior branch, respectively turning forwards and backwards. Also near the crest of the ilium two trunks will be found turning down over the gluteal region, namely, the lateral branch of the last dorsal nerve [524], and behind it the iliac branch of the ilio-hypogastric [525]. These nerves having been preserved, the dissection is to be pursued further back, till the posterior border of the external oblicme muscle of the abdomen is reached in the hollow outside the position of the erector spinse muscle; and the attachments of the muscle to the eight lower ribs, and their interdigitation with origins of the latissimus dorsi [254] and serratus magnus [256] muscles are to be made distinct. An oblique incision is to be made through the external oblicpae muscle about two inches from the
