—Two methodsmay be employed : (a) a lateral view of the skull, showing the air sinuses inprofile ; (6) antero-posterior, the plate on the front of the skull and the tubebehind. A direct antero-posterior view does notshow the sinuses at allwell, the overlapping ofthe shadow^ caused by theoccipital and temporalbones obscuring the detailin the frontal and acces-sory sinuses. There aretwo routes by which therays may be passed throughthe back of the skull.

(2) A better methodis to place the patient facedowaiw^ards on the photo-graphic plate, the latterbeing placed at an angle of 25 degrees.
