Fifth Pair—These are 65 mm. long, measured under stan¬ 
dard con litions. with proximal articular widths of 18 mm. The 
epi-pleural processes are 15 nun. from the distal ends of the 
main ribs, and 22 nun. across the ribs and processes at their 
apices, and at their united base lines they measure 1 1 nun. 
across. The costals are 28 mm. long. 
Sixth Pair—These ribs are 68 mm. long, with proximal 
articular measurements equal to 19 nun. The epi-pleural pro¬ 
cesses arise 18 mm. from the distal ends, and expand to 22 mm. 
at their tips, with the main ribs included. The costals are 35 
mm. long. 
Seventh Pair—These ribs have a length of 67 mm., and 
proximal articular measurements equal to 20 mm. The pro¬ 
cesses arise 18 mm. from the distal ends, and expand at their 
tips to 13 mm. The costals are 40 mm. long. 
Kighth Pair- -'Phis and the succeeding pair of ribs were 
measured in situ upon the synsacrum, to which they were left 
attached for future reference. Their total length may be placed 
at 67 mm., with proximal articular widths equal to 22 mm. The 
processes arise 30 mm. from the distal ends, are but slightly 
developed, and measure 13 mm. across their tips, including, of 
course, the width of the ribs themselves. The costals are 47 
mm. long. 
Ninth Pair—These ribs are 67 mm. long, with proximal 
articular measurements equal to 21 mm. They develop no epi- 
pleural processes, but support costals 35 mm. long, which, as 
already state !, reach the sternum by direct articulation. 
BOXES OF THE PELVIC LIMB. 
Femur.-—This bone has a total length of 126 mm., with a 
proximal width of 27 mm., and a distal width of 28 mm. The 
diameter of the shaft in its centre is slightly under 13 mm. 
The trochanter major is highly pneumatic throughout, the 
actual pneumatic fossa being situated upon the convex pre- 
trochanterian surface, 14 mm. from the proximal end of the 
bone. The fossa, or foramen, is 6 mm. long and 3 mm. wide. 
There is no indication of a trochanter minor. The epi-trochan- 
terian surface is wide and evenly rounded, passing with a very 
slight interruption into the head. Below, the constriction form¬ 
ing the neck is well defused : the upper third of the head is ex¬ 
cavated for the ligamcntum teres. The nutrient foramen is 
situated, as usual, upon the posterior surface of the shaft, and 
in this case 65 111111. from the proximal end. 
l he popliteal fossa is large, but very shallow ; the hbular 
groove is deeply impressed, as is also the rotular channel. The
