In both genera, as in the okapi, there is a vacuity in front of the orbit.
A preorbital vacuity of such dimensions as to exclude the lachrymal bone from articulation with the nasal.
In the skull the gland-pit is shallow, and the vacuity of moderate size; the nasal bones are well developed, and much expanded at the upper end.
Adherents of the Yoga philosophy and the system of ascetic practices enjoined by it with the view of mental abstraction and the supposed attainment of superhuman powers - practices which, when not merely pretended, but rigidly carried out, are only too apt to produce vacuity of mind and wild fits of frenzy.
The squamosal bone is large and either in contact with the frontals and parietals or separated from them by a vacuity; the orbit is sometimes roofed over by bone.
