I believe, however, that the size or deep-seat-edness of a growth should not stop us from operating on a patient whois certain to die unless relieved, because many cases of this kindhave shown that in these days of antiseptic surgery a patient may Fig. TUMOR Photograph of tumor of left temporo-sphenoidal lobe, causing hemianopsia, word-deafness, ataxic aphasia, hemiplegia, motor oculi paralysis, and convulsions. thus be snatched from out of the shadow of death. Considering allthese difficulties, therefore, the question arises as to what percentageof success we can expect in operations for cranial tumors. The accom-panying table is based upon an investigation made for me by myfriend Dr. 11. S. Newton : Total number of operations for tumor to Sept. 15, 1892.
