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 branchlet, 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 petrosal, 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
