COMPARATIVE MYOLOGY. 



A.N extensive section devoted to this subject would be somewhat out of place 

 in an ordinary class-book ; • therefore for fuller descriptions and details the 

 student must have recourse to exhaustive works of reference, or, what is still 

 better, to his own dissections and observations, bearing in mind the typical 

 branch of the subject. We shall endeavour to point out where the more 

 important muscles of the domesticated animals present features which, for our 

 purpose, are worthy of comparison with those of the selected type ; and in 

 this attempt we observe very generally the same sequence as to regions and 

 groups that we have adopted in describing the muscles of the horse. 



RUMINANTIA. 



Subcutaneous Region. 



The panniculus carnosus in the cervical region is mostly aponeurotic ; a 

 muscle which resembles the sterno-niaxillaris of the horse is sometimes 

 regarded as constituting its inferior tieshy portion. In the head it resemblefi 

 that of the horse, but there is a fleshy expansion in the frontal region — the 

 so-called frontalis muscle — which is apparently a part of the panniculus. In 

 the trunk there is no very important deviation from the arrangement already 

 ■described.
