regarded the unseated Monkey, utterly confounded by his downfall, and the accompanying shouts of laughter from the bystanders. The Pig-tailed Baboon being very clever, very agile, and able to use his jaws admirably in digging, eating, and fighting, should have a good skull, and certainly that of an adult, although useful is extremely ugly. The brain-case is even for a Baboon small in comparison with the rest of the skull, and it is hidden in front by the large prominences over the orbits; it swells out behind, and is marked by a side crest, which passes backwards to meet that of the other side from above each ear. The orbits are separated by a straight (vertical) ridge of bone, which gives a curious look to the face, and makes the eyes look straight to the front along the swollen nose. The openings for the nostrils in the skull (anterior nares) are large and rather oval, and the upper jaw is as it were nipped in above the grinders, and then swollen out above. The long nose bones (nasals) are separated by a slight depression from the great ridges of the upper jaw. The huge upper canine teeth are most extraordinary. They are slim, slightly curved, long (1½ inch), and sharp at the tip; when examined they are almost rapier-shaped or triangular in outline, the front of the triangle is grooved, and the back is a sharp cutting edge. The groove is for the top of the lower canine which works into it, and the sharp edge behind cuts upon the tooth in the lower jaw behind the lower canine (the first pre-molar), pushing it backwards and displacing it. These fangs are very terrible to look at, and yet it appears that their principal work is done with the back edge of the upper one grinding and cutting on the curiously-started tooth of the lower jaw. They are capital holders, root-cutters, and nut-crackers. THE SPHINX BABOON.[64]
