The acromial deltoid is small, and arises from the top of the 
acromion (0* 1 2). The clavicular is much larger, arising from the clavicu- 
lar inscription, where it blends vs^ith the cleido-mastoid and clavicular 
trapezius (0'54). The scapular is much smaller (0*09), arising from 
the middle third (Galera, or half, Civet) of the spine of the scapula, 
and inserted the highest up of all, under the acromial part. The 
clavicular part is inserted partly into the brachialis anticus, and 
partly into the humerus (Galera), or into the radius (Civet). 
Supraspinatus was in two parts in the Civet, one from the 
epiphysial element of the prescapula, the other weaker from the upper 
surface of the spine ; it exceeded infraspinatus by about ^ (supra- 
spinatus = 0-34). 
Teres minor arose from the anterior third of the scapular border, 
and was quite distinct in the Civet. In Galera it is very short, and its 
nerve has no ganglion ; its tendon of origin is slightly connected to 
that of the long head of the triceps. 
Subscapularis is Aveak (0*35), with three sets of fibres ; a middle, 
Avith a tendon in front; a supra- marginal, and an infra-marginal. 
In the Galera there are four slips, of which the inferior (subscapulo- 
humeral) is the most detached and fleshy; none of the capsular 
muscles pierce the Shoulder joint. 
Serratus magnus arises from 4-7 cervical vertebrae and 1-7 ribs in 
Civet (8 in Galera). It has nothing remarkable about its lower 
border, nor has it any anomalous relation to the rhomboid, where the 
prolonged scalenus posticus lies in front of it. It does not extend 
far forwards. 
Scalenus anticus is small, and passes from the sixth cervical trans- 
verse process to the first rib. S. medius arises from the 3rd-6th verte- 
brae. Scalenus posticus passes from the 4th-6th vertebrae to the 3rd- 
6th ribs inclusive. The rectus abdominis in Viverra is inserted into the 
whole length of the mesosternum and by tendinous fibres into the pre- 
sternum. There are seven inscriptions in Yiverra, six in Galera, in 
which the muscle is attached to the first rib. The external oblique 
in the latter arises from the 5th~14th ribs. 
The great pectoral consists of four laminae ; 1st. Presterno-hume- 
ral, slender, transverse, and with no fibres common to its fellow of 
the opposite side. This in Galera is distinct, and less superficial. 
2nd. Anterior meso-sterno-humeral passed from the first and second 
sternebers, to be inserted at the lowest point of the pectoral crest of 
the humerus ; the posterior meso-sterno-humeral arises from the 2nd to 
the 5th sternebers, is inserted into the upper part of the pectoral crest. 
4. The xiphisterno-humeral is slender, and inserted into the fascia 
over the origin of the biceps, beneath the others. These parts in the 
Civet are to each other as the following proportions: — 0"13, 0*37, 
0.96, 0-16, 
The fourth pectoral, or the brachio-lateral part of the panniculus, is 
large and extensive, and is inserted into an ' ^ achselbogen, " closely 
tied to the humerus.
