referable to the mastoid. The X-ray mayaid in clearing up such cases. Bussey (11) has recently re-ported li cases (13 collected from the literature, and one ofhis own) of mastoid abscess, in which the signs were anomal-ous, few or no symptoms referable to the mastoid, and no dis-charge from the ear. The X-ray may be valuable in this type. Only a small number of the milder acute cases were exam-ined, and no conclusions could be drawn. In several aslight haziness over the mastoid was noted wihioh disappearedagain after spontaneous recovery. It is not unlikely that valu-able information may be gained regarding the milder acutecases, if plates more technically perfect than those to be ex-hibited are obtained. Those severe acute cases accompaniedby extensive bone destruction with abscess formation can, ofcourse, be easily recognized.

Lange: Mastoid Examination 9 mastoid was diagnosed from the skiagram and verified byoperation. In one of these cases the drum could not be seenowing to swelling of the external auditory canal. Furunculosiswas being considered until the X-ray showed the bone destruc-tion in the mastoid. In conclusion, it may be stated that the interpretation ofmastoid skiagrams demands much study, and the enthusiasticco-operation of the otologist. Without the latter, little canbe accomplished, for the otologist must correlate the X-rayand the clinical findings, and check up the results by opera-tion. For such aid in interpretation and for the privilege ofexamining many of the clinical cases, I am indebted to Dr. S.Iglauer (12) at whose suggestion and direction I undertookthe work. Since writing the above it has been found advantageous incertain types of skulls to decrease the angles of inclination ofthe axis of the rays.
