to -which the Calocephalus vitulinus belongs, and seems to 
form a part of the osseous bulla. The fourth fragment is the 
basal portion of a horn of the red deer (Cervus elephas), with 
a part of the brow antler cut and fashioned by a sharp instru- 
ment. The fifth piece is a branchlet of the same species, cut 
and hacked apparently for the purpose of breaking it from 
the stem. The sixth fragment is a small bit of bone, evidently 
a portion of a lesser branchlefc, which is also cut and polished. 
The seventh specimen is a portion of the left side of the lower 
jaw of the Bos longifrons, and contains the second and third 
deciduous molars and first permanent molar. The third de- 
ciduous molar has three large vertical columns, each with an 
inner and outer acute summit, the inner summits rising higher 
than the outer. There are two accessory columns, one on 
each side of the outer surface of the large middle column, 
extending upwards to the base of its summit, with distinct 
concentric layers of crusta petrosa, enamel, and central den- 
tine. This three-columned deciduous tooth is known to be 
succeeded, between the second and third year, by a permanent 
premolar with only two columns. The loose teeth also belong 
to Bos longifrons ; the tooth marked No. 8 is the first true 
molar on the right side of the upper jaw ; No. 9 is the last 
permanent molar on the left side ; No. 10 is a third deciduous 
premolar on the right side ; No. 11 is the second deciduous 
premolar, also on the right side, and all belonging to the upper 
jaw. The larger column in these deciduous premolars is 
situated posteriorly, and the smaller in front ; which character 
serves to point out whether they belong to the right or left 
side of the jaw. The next two specimens likewise belong to 
Bos longifrons ; No. 12 is a cancellous horn core ; and No. 13 
is the distal portion of the right humerus. The species to 
which the name of Bos longifrons has been applied by Pro- 
fessor Owen is considered to be the original stock from which 
the present domesticated breed of small Highland cattle are 
derived. The fourteenth specimen is a portion of the right 
lower jaw of a small sheep, containing the two last premolars 
and first true molar, with sockets for the first premolar and 
for the incisors. The external opening of the inferior maxil- 
lary canal is situated nearly midway between the anterior
