The tests were made with needles on patientssufficiently intelligent to make comparatively accurate observations;certain inaccuracies are, however, bound to occur, as marginal areas 568 LOCAL ANESTHESIA show diminished sensibility and adjacent surfaces are overlapped bythe opposite nerve in a zigzag manner. In the median line of the face the limits between the two sides wererather sharply defined, as variations were not so numerous as had pre-viously been supposed; still this overlapping may take place suffi-ciently in spots to make it always advisable to anesthetize both sidesin operations approaching the median fine. On the skull, in the midline, the area of anesthesia extended wellup toward the vertex capitis, but laterally in the region of the auricle.

He calls attention to this extendedarea of anesthesia as offering favorable opportunities by this methodfor trephining, etc., upon the sinciput. In the face the area of distribution of the cervical nerves (nervusauricularis magnus, cutaneous colli) projects from below laterally moreor less extensively into the trigeminus region, so that we never canreckon on pure trigeminus anesthesia in the region of the auricle,lateral temples, cheeks on the sides, the parotid gland, at the angleof the jaw and chi
