mesial face of the trapezius laterally and to the 
longissimus dorsi ventrally and spinalis dorsi 
mesially and ventrally. Secondary abscesses 
of fistula of the withers said to be located “un- 
der the scapula” are in reality located under 
this muscle, resting upon the longissimus dorsi 
but without any obstacle against the filtration 
of pus further down than under the upper part 
of the serratus dorsi. Pus seldom goes to a 
lower level because the latter muscle is at- 
tached firmly to the costal surface and above to 
the mesial face of the scapula, forming a space 
having a firm floor but without anterior and 
posterior walls. 
Rhomboideus Cervicalis 
The rhomboideus cervicalis is the forward 
elongation of the thoracalis, extending toward 
the head along the ligamentum nuche as far 
forward as the axis. Its insertion is the an- 
terior part of the mesial face of the cartilage of 
prolongation. Its surgical importance lies in 
the fact that its ventral margin just in front of 
the scapula affords a point of invasion into the 
seat of a typical fistula (Fig. 2). It is also so 
closely related to the ligamentum nuche that 
it seldom escapes attack from the morbid pro- 
cess. and when heedlessly sacrificed in resect- 
ing the ligamentum nuche a pronounced de-
