There is an irregular-shaped metal frag-ment about I j/^ X 11/^ X ^ cm. in diam-eter situated cm. vertically beneath theskin mark on the right side of the head, thepatient lying on his left side with head ina true lateral position. The surface markingscorrespond to the inferior portion of the par-ietal bone nearly at the squamous suture SECTION 6 FiGUKK 9. being 5 cm. superior and cm. posteriorto the external meatus acusticus, Reids baseline being taken as a guide to these measure-ments. The anatomical location is in thesuperficial part of the right angular gyrus ofthe parietal lobe, being about i cm. withinthe brain substance. The location of themetal fragment corresponds to section 6 ofthe Eycleshymer-Shoemaker Cross Section Anatoiiiy, being 6 cm. from the posteriorsurface and cm. from the lateral side. Operative Findings.—As a result of theabove roentgen findings, it was decided toremove the foreign body, inasmuch as it wasquite superficial. On March 26th the skullwas trephined over the localization mark, thedura split and the foreign body was re-moved, it being imbedded just beneath thecortex, as the localization findings trephined bone was replaced and the pa-tient made an uneventful recovery.
