process.” That portion of the humeral head which fails to find 
lodgment in the articular cavity of the coracoid rests against a 
wide band of ligament that is stretched between the coracoid 
and the scapula* In consequence of this arrangement there is 
no “ os humero-scapulare " present.

The united clavicles form a powerfully constructed fur- 
culum, which is inrted ligamentously to the sternum, the liga¬ 
ment being attached to a process (interclavieal) developed at 
the blending point of the original clavicular bones. The extreme 
length of the furcultmi is 62 mm., and its greatest width 75 mm. 
Xeglecting the'Width of both bones, and measuring across the 
enclosed space, it will be found to vary from 48 mm. in the 
centre to 3b' mm. across'the upper processes. 'The greatest 
width of either moiety is at a point slightly lower than the cora- 
coidal articular surfaces, where the bones expand to 20 mm. 
Near the articular surfaces there are large fossre. penetrated by 
pneumatic foramina. When placed upon the measuring base 
line (the outer surfaces and processes being downwards) the 
iurculum rises 37 mm. vertically above the measuring board.

The humerus is 188 mm. long, with a proximal width of 
47 mm., including the ulnar tuberosity and delto-pectoral crest, 
while the distal width of the bone is 35 mm. There is a large 
sub-trochautcrian fossa, whose walls extend downwards for 20 
111m. before they subside upon the shaft: nowhere does its wi 1th 
exceed 12 mm. This fossa is extensively perforated by pneu¬ 
matic foramina. Iklow the humeral head there is a well-marked 
coraco-humeral groove, which, however, does not extend on to 
the palmar aspect of the bone. The nutrient foramina are 
situated as follows:—Immediately below the sub-trochantcrian 
fossa there is one, whose position upon the shaft is best stated 
by a measurement taken from the head of the humerus, under 
which conditions the distance is 57 mm. The second is upon 
tlie palmar aspect of the shaft, 66 mm. lower than the first one, 
and 68 mm. from the distal end of the bone. The supra condylar 
fossa is large, but shallow, and the ectepicondylar process, 
although present, only rises to 4 111111. above the general line of 
the shaft. In its centre the shaft is nearly round, its diameter 
being 13 mm.
