The operation is deferred for twenty minutes togive the anaesthetic solution time to obtain its maximum this interval the patient is kept under attentive observa-tion, and symptoms such as headache and nausea are combated bythe administration of cold black coffee. With regard to the operation, there are certain indispensabledetails to be observed; apart from these it is conducted in the usualmanner for a radical mastoid. To summarise them, a soft pillow.

Burrs may be substituted for thechisels with advantage ; no more force than is absolutely necessaryshould be exerted by the retractors. From time to time during thecourse of the operation cold black coffee is administered to thepatient; this is effected by allowing him to siphon it from a jug b_ymeans of a tube. The technique for acute mastoids only differs from the foregoingin that no injections of cocaine-tonogen solution are needed for theexternal auditory canal, and, moreover, an occasional supplementary 428 The Journal of Laryngology, [August, 1905. injection of eucaine solution is made near the tip of the mastoidprocess.
