GENERAL CONSIDERATIONS ON THE STRIPED MUSCLES. 241 



coverin- muscles sliould not be entirely excised, but ought to be cut through tlie middle, across 

 tbeir fibres and the euds thrown back ; in this way it is always pc^sible to replace a muscle 

 bv brlDcring the two portions together ; the study of its relations is then much more easy. The 

 cellular^issue is got rid of by removing it with the forceps, and carrying the edge of the 

 scalpel in the re-entering angle formed by the cellular layer and the surface of the muscle. 

 This method also suffices for removing aponeuroses when they are slightly adherent to the 

 muscular fibres. But when they give attachment to these by their under face, as may be 

 noticed in the external scapular aponeurosis, it is necessary to have recourse to the method 

 indicated above. To remove fat, glands, etc., scissors will be found very advantageous. 



Order tofolloio in preparing all the muscles of the same subject, so as to derive most advantage 

 therefrom 1. Place the subject in the first position, and commence by studying the muscles of 

 the inferior abdominal region. Then excise them, leaving the posterior extremity of the 

 deep pectoral muscle, the prepubic tendon, and the crural arch intact. The abdommal cavity 

 having been emptied of the viscera it contains, dissect and study successively the diaphragm.

 position, and one after another may be dissected the muscles of the ear, those of the superior 

 cervical region, the croup and costal regions-except the triangularis sterni-and the spinal 

 region of the back and loins. . ,. . ,

* ^I'^Separate the two posterior limbs by sawing the femurs through their middle, and proceed 

 to the dissection of the muscles of the posterior leg and foot. 



5. By means of another application of the saw across the middle of the loms, the pelvis is 

 completely isolated for the preparation of the coccygeal muscles, and the deep muscles of the 

 internal crural region, nearly as they are represented in figures 39 and 40. 



6. The animal being placed on its side, the pectoral cavity is opened by sawing through 

 the ribs near their extremities ; on the two particular portions thus obtained may be 

 studied, in one part, the triangularis sterai, and in the other the deep muscles of the inferior
