182 Description of the Plates. 



The integument has been turned back on the right side, together 

 with the musculo-cutaneous vein, the superficial branches of which 

 extend from the knee to the shoulder ; part of the muscular wall 

 of the body has been removed on that side, but part has been left 

 in situ ; and the main trunk of the musculo-cutaneous vein is seen 

 crossing a slip which the oblicfims externus muscle receives from the 

 scapula ; on the left side the muscular and cutaneous elements of 

 the wall have been turned back whilst remaining in their natural 

 connection with each other and Vv^ith the epigastric vein; the 

 shoulder girdle has been cut through the middle line, and fastened 

 out on either side so as to expose the lungs, heart, and great 

 vessels ; the liver has been removed with the exception of a small 

 part of its substance, as have also the stomach and intestines down 

 to the lower end of the rectum. 



a. Intermandibular space. The skin is left in situ anteriorly in 

 the symphysial angle; immediately posteriorly to its cut 

 edge is seen part of the mylohyoid or submaxillaris muscle ; 

 and posteriorly again, and at a deeper level, the converging 

 hyoglossi in the middle line, and on either side of them the 

 geniohyoids, with a glandular body resting upon each of 

 them. 

 h. Tetradactyle hand. The thumb has its basal joint more or less 

 tumid in this, a male, specimen. 



c. Muscles of thigh. The line points to the sartorius, which is 



bordered externally by the vastus internus, and internally 

 by the adductores and recti interni. See Ecker, Die Ana- 

 tomic des Frosches, p. 115. 



d. Point where the musculo-cutaneous veins, constituted by 



factors from the regions of the head and face, as also and 

 mainly from those of the back and flanks, turn inwards to 

 pass over a slip going from the scapula to the external 

 oblique muscle and join the axillary vein. See Ecker, I. c, 

 p. 81 ; Gruby, Ann. Sci, Nat., Ser. ii. tom. xviii., p. 224. 



e. Vein, called 'epigastric' by Rathke, ' umbilicar by Bojanus 



and Jourdain, ' vena portae accessoria' and ' vena ahdominalis 

 inferior s. anterior,' by other authors. This vein is mainly 

 constituted by the convergence of the two descending 

 branches from the femoral veins seen at / in the figure, 

 but it receives twigs also from the abdominal parietes, and
