“Two specimens of prehistoric flint arrow-points or spear-heads found inserted in human bones were sent to the National Museum by Dr. John E. Younglove, of Bowling Green, Kentucky. One had pierced the pelvic bone and the other is still inserted in the head of a human femur. The material of both points is the black or brown lustreless pyromachic flint, common to the country in which it was found. The specimens came from a cavern about four miles northeast of Bowling Green, and an equal distance from Old Station. [Illustration: FIG. 92. (S. 1–1.) Showing relation of specialized leaf-blade implements of various kinds to the original blade. ] “Most of the specimens of arrows and arrow-wounds in the Army Medical Museum pertain to modern Indian warfare. The arrow-points of iron or steel show, by actual experience and ocular demonstration, the effect of these projectiles upon bones, the endurance of the patient, and the skill of the surgeon; consequently they are of considerable interest. They also show that none of the arrow-points were poisoned. [Illustration: FIG. 93. (S. 1–2.) Quartzite knife. P. D.

Seven days later he was admitted to the hospital at Fort Concho, Texas, having traveled part of the distance on foot. He complained of soreness from the gunshot wounds, but spoke lightly of the ‘scratch’ made by the arrow on the side of his head. The gunshot wounds healed, but cerebral complications developed. An effort was made to reopen the wound in the temple, which proved unsuccessful on account of the resistance of the temporal bones, and doubt as to the cause of the existing symptoms prevented the surgeon from making a free incision. The case terminated fatally September 19, and the autopsy revealed the real injury to have been caused by the entry of the iron arrow-head half an inch from the external incision. “A Mexican was killed by an arrow in an Indian fight seventy-five miles northwest of Fort Concho, Texas, February 22, 1868. He was treated by W. M. Notson, Assistant Surgeon, United States Army, who reported:— [Illustration: FIG. 94. (S. 1–1.) Seven chipped objects. In the centre is a peculiar object with wide shoulders and angular sides. This form is found in the East, but is not common. Its purpose has never been satisfactorily explained. The object to the right with straight sides and point made angular is also seldom found save east of the Mississippi River. Why it was made in this form is not known. Material: jasper. H. K.
