Study of the various fragments found, therefore, seems to lead to some- 
what diverse results. The temporal bone displays undoubtedly primitive 
features ; the skull-cap seems closest in point of size and general characters 
to the Cro-Magnon type ; the mandible appears to be in a slightly more 
advanced stage of evolution, and to be comparable on the whole to the 
Bantu. 
Note upon the Fragments of the Limb-bones of the Boskop 
Remains. 
By K. B. Thomson. 
The portions of the Boskop skeleton, other than those of the skull, have 
been submitted to me by Dr. Pcringuey of the South African Museum for 
a preliminary report. 
The fragments, as far as I can determine, consist of two portions of the 
femoral shaft, one j^art of each left tibia and fibula, and one part of each left 
radius and ulna, these latter four being in close relation to each other in a 
mass of what apj)ears to be ferruginous laterite. All the fragments are 
petrified to a large extent. Inspection under X rays has been of some help 
since certain exposed j)oi'tioiis of the bones are more opaque than the 
adjacent laterite. 
The upper fragment of the femur, which is possibly of the right side, is 
a portion of the shaft 131 mm. long, with a maximum breadth of 36 mm. 
The anterior and lateral faces are fairly intact, but the medial and posterior 
aspects are absent. Its condition is such that it is difficult to state not only 
to which part of the proximal three-quarters of a femoral diaphysis it may 
be apportioned, but also to which side of the body it may belong. 
The lower fragment of the femur belongs to the distal third of the right 
femoral diaphysis. It is 98 mm. long, with a greatest breadth of 46 mm. at 
its distal end. All the faces of this portion are pretty complete, the posterior 
one — planum popliteum — being the best preserved of all. Both epicondylic 
lines are distinct. 
The portions of the tibia and fibula are from the distal thirds of the 
diaphyses. The length of the tilnal fragment is 90 mm. and that of the 
fibula 56 mm. 
The radius and ulna are l^oth represented by considerable portions of the 
shafts, that of the ulna being represented from about a point midway 
between the coronoid process and the position of the nutrient foramen to a 
point roughly about 25 mm. (1 in.) short of the distal end. It measures 
155 mm. long. The radial shaft is more complete, is 188 mm. long, and 
embraces that portion from the region of the lower part of the neck to a 
point well towards the distal extremity.
