TRANSORBITAL lobotomy is a rather new procedure, and a relatively safe one, so that up to the present time there has been little material for the study of the lesions produced by the operation. Preliminary reports by Freeman,1 Freeman and Watts,2 and Walsh3 have been concerned principally with the location of the incisions in relation to the thalamofrontal radiation. The present study is based on 15 specimens from patients on whom necropsy was performed at various periods up to a year after operation. Details concerning these cases are given in the accompanying table.

In the peformance of transorbital lobotomy, a sharp slender instrument is inserted into the conjunctival sac 3 cm. from the midline, aimed parallel with the bony ridge of the nose and driven through the orbital plate to a final depth of 5 cm. within the frontal lobe. Lateral and medial cuts, through the white
