The margins of this laceration at all points were jagged and irregular, with additional lacerations extending in varying directions and for varying distances from the main laceration.
In addition, there was a laceration of the corpus callosum which is a body of fibers which connects the two hemispheres of the brain to each other, which extended from the posterior to the anterior portion of this structure, that is the corpus callosum. Exposed in this laceration were portions of the ventricular system in which the spinal fluid normally is disposed within the brain.
When viewed from above the left cerebral hemisphere was intact. There was engorgement of blood vessels in the meninges covering the brain. We note that the gyri and sulci, which are the convolutions of the brain over the left hemisphere were of normal size and distribution.
Those on the right were too fragmented and distorted for satisfactory description.
When the brain was turned over and viewed from its basular or inferior aspect, there was found a longitudinal laceration of the mid-brain through the floor of the third ventricle, just behind the optic chiasma and the mammillary bodies.
This laceration partially communicates with an oblique 1.5 cm. tear through the left cerebral peduncle. This is a portion of the brain which connects the higher centers of the brain with the spinal cord which is more concerned with reflex actions.
There were irregular superficial lacerations over the basular or inferior aspects of the left temporal and frontal lobes. We interpret that these later contusions were brought about when the disruptive force of the injury pushed that portion of the brain against the relative intact skull.
This has been described as contre-coup injury in that location.
This, then, I believe, Mr. Specter, are the major points with regard to the President's head wound.
Mr. Specter. Do you have an opinion, Dr. Humes, as to whether there were dumdum bullets used specifically on this wound which struck point "A" of the head, on 388?
