The den-tiaskiascope, or endodioscope, first described by Dr. Macintyre and usedfor examining the hard and soft tissues about the bones of the face, nose,and larynx, deserves mention. Dr. Macintyre writes as follows :^ Thefluorescent screen is placed inside of the mouth and the Crookes tube out-side, or vice versa.

The more obtuse the facial angle, the more acuteshould be the angle between the bundles of rays and the base of the skull, or a line co
