    Supra-orbital ridge.—The eyebrow and supra-orbital ridge are examined by passing the finger over their surface. If any abnormal swelling is discovered, its connection v/ith the skin or bone, and its relation to the orbit and orbital contents, is investigated ; and it is also palpated to ascertain whether it fluctuates, is solid, or is as hard as bone. Proptosis.—If the eyes appear to differ in prominence, the examiner should stand behind the patient, who is seated, then raise each upper lid with the forefinger, and draw the head back- wards until the cornea of the unaffected eye is in a line with the eyebrowand the observer's eye; he will then be able to see if the cornea of the other eye is in advance of this plane. Enophthalmos.—When it is suspected that an eye is unduly sunken in its orbit, the observer holds a flat ruler, or a sheet of paper, edgewise against the angle of the mouth and the eyebrow, directly over the centre of the cornea, and notes the distance between the sur- face of the cornea and the ruler. By repeating the observation on the other side, an accurate measurement can be made of any difference in the position of the two eyes. The orbit.—The orbit is examined through the lids by palpation of the margins, and of the interval between the walls of the orbit and the globe ; but if it is desirable to feel very deeply,
