extremely small, and will only just give entrance to an ordinary 
dissecting needle; long after dissection blood was found oozing 
from them. .Below these foranrna the shaft is thin to trans¬ 
parency, and upon the inner side bends round in a semi-circle to 
a feather edge. Externally the shaft is squared, and presents a 
hat surface, 13 mm. wide in its centre. Posteriorly, the tendonal 
canal commences by two distinct but shallow grooves, that are 
bordered by the two calcaneal processes, and after a passage of 
30 mm. down the shaft they subside. The larger of the two 
processes is 11 mm. long. Ppon the whole the groove is flat 
and wide, reaching at a point situated 30 mm. from the proximal 
end of the bone a width of 15 mm., while in the centre of the 
shaft (which is 13 mm. wide) it measures 9 mm. 1 )i-tally the 
third un-ankylosed carpal, presenting an articular facet to the 
hallux, is 27 mm. long and 15 mm. wide at its trochlear surface. 
Trochlea Xo. 2 is the same width, viz., [5 mm., including the 
articular surface and styloid process; Xo. 3. is 8 mm. wide, and 
Xo. 4. 5 mm. wide (articular surface only). Trochlea Xo. 4 is 
drawn upwards 3 mm. from the common level of Xos. 2 and 3. 
while that of the hallux is 10 mm. higher still. The foramen for 
the passage of the anterior tibial artery is situated 17 mm. from 
the distal end of the bone, and through it a branch of the artery 
passes immediately through the hone, while at right angles to 
this foramen there is a second (as in the chestnut-faced owl), 
which transmits a tendon to the inter-trochlear space. 
TOES. 
Hallux*.—The first phalanx of this toe is a stoutly fashioned 
bone 40 mm. long, and proximally 17 mm. by 11 mm., while 
distally the measurements are 10 mm. by 10 mm. The articular 
surfaces are deeply impressed, and the processes and fossae for 
ligamentous and muscular attachment are in keeping with the 
need for enormous raptoral power. The second phalanx is the 
ungual one—a bone that measures 44 mm. along its chord. 
Proximally it is 15 mm. bv 12 mm. upon its articular surfaces, 
or 19 mm. if the process for the attachment of the erecting liga¬ 
ment is included. 
*Kote.—The measurements given for all ungual phalanges 
were made after the removal of the horny claw sheaths. 
Second Toe.—The second toe consists of three bones, the 
proximal one being practically ankylosed to the succeeding one, 
and, although the latter phalanx was separated during dissec¬ 
tion. it was only at the cost of a fracture of the under surface 
of the hone. The proximal phalanx is 16 mm. long, 18 mm. 
wide, and 12 mm. deep. The second phalanx is 33 mm. long.
