On removing the cal-varium (which was done without injury to the brain substance) the meningealarteries were found fully injected. On removing the dura the terminal branchesof the cerebrals were found fully injected. To prevent the escape of the injec-tion mass the internal carotids and basilar artery were ligated before viscus was then removed from the skull and was placed in a specimen jarcontaining a 10 per cent solution of formaldehyde and sufficient cotton to give.

After an immersion of 48 hours it was removed from thespecimen jar and the exposure to the x-rays was made. Two exposures weremade. The first was of the entire brain with the base toward the plate. Thesecond was of both hemispheres with the mesial surface of each toward theplate. With both hemispheres on the same plate the lateral view was foundto be of much value on account of presenting both a normal and an abnormalspecimen for differential study. To illustrate the results of this method, photographs of two plates are pre-sented (Figs 2 and 3). There was a clinical diagnosis of cerebral hemorrhage. The autopsy diag-nosis made without sectioning the brain was arteriosclerosis; dififuse subarach-noid hemorrhage from the right and left posterior cerebellar arteries; throm- R
