figures enable the dissector to identify without trouble 

 most of the muscles. But this part of the work, at 

 least, contains too many inaccuracies to make it a safe 

 guide. In like manner the value of a recently pub- 

 lished hand-book^ is much impaired by inaccurate state- 

 ments regarding- the origin and insertion of many of the 

 muscles described. 



Finally, that most original and valuable work, the 

 "Anatomical Technology," only includes a description 

 of the muscles of the chest, shoulder and fore-leg. 

 The accurate nature of all the descriptions in the 

 "Technology" has long been recognized, and the 

 few points in which our description of the pectoral 

 muscles differs from that of Wilder and Gage*, are 

 doubtless varying points. In spite, however, of its ac- 

 curacy, the account given in the "Technology" of the 

 cat pectorals seems to us an unnecessarily difficult one 

 to follow. This is in part due to the manner in which 

 the group is subdivided. 



ABDOMINAL MUSCLES. 



External oblique. This muscle arises along its ex- 

 ternal border from the nine last ribs and from the lum- 

 bar fascia. The attachments to the ribs interdigitate 

 with the slips of the serratus niag-nus, and lie beneath 

 the latissirmcs dorsi. The lumbar fascia from which 

 the muscle arises is the superficial fascia which may 

 be peeled from the underlying transversalis abdom- 

 inis, and mav be traced to the spinous processes of the 

 vertebrae. 



Along its inner border the muscle passes into a broad,
