0, occipital protuberance ; C, 

 ti'ausverse process of the atlas ; D, 

 first dorsal vertebra ; L, first lum- 

 bar vertebra ; S, first piece of tlie 

 sacrum ; Co, first piece of tlie 

 coccyx ; a, acromion ; h, Ijase of 

 the scapula ; i, crest of the ilium ; 

 1, ui)per and back part of the sterno- 

 mastoid muscle; 2, splenius, levator 

 ainruli scapulcT, and other deep 

 lunscles ; 3, 3, upper and lower 

 Gild? of the line of origin of the 

 trapezius muscle ; 3', triangular 

 tendon attached to the inner end of 

 the spine of the scapuhx ; + , half of 

 tiie oval tendon belonging to the 

 two ti'apezius muscles in the lower 

 cervical and npper dorsal region ; 



4, 4, latissimns dorsi ; 4', 4", line 

 along which the latissiraus dorsi 

 takes origin from the lumbar fascia ; 



5, infrasi^inatus ; 6, teres niiinor ; 

 7, teres major ; 8, deltoid ; 9, ex- 

 ternal olilique muscle of the ab- 

 domen; 10, gluteus medius, covered

 gluteus maximus from the posterior 

 part of ilium to the coccyx ; 11', 

 its insertion into the fascia lata

floor of tlie bicipital groove 

 of the humerus, a little 

 higher than the insertion of 

 the teres major. From this 

 twisting of the muscle upon 

 itself, the anterior surface of 

 the tendon is continuous 

 with the posterior surface of 

 the rest of the muscle. 



Briation.f. — The latissimiis 

 dorsi is subcutaneous, except at its 

 origin from the dorsal vertebra;, 

 where it is covered by the 

 trapezius, and at its insertion, 

 where it dips into the axilla. 

 It rests on part of the rhom- 

 boideus major and infraspina- 

 tus, on the teres major, seiTatu-s 

 posticus inferior, vertebral apo- 

 neurosis, external intercostal
