injury. Before, he had been a farm boy, but he now blossomed 
out as a school teacher, and subsequently as phrenological 
lecturer, temperance orator, Justice of Peace, map agent, labor 
agitator, and saloon keeper. He recently died in Grand Rapids, 
Michigan, from the effects of chronic alcoholism, and the only 
marked mental aberration ever manifested was a decided disin¬ 
clination to pay his lawful debts, including the extremely mode¬ 
rate bill of the attending surgeons. 
4. In July, 1872, I was personally called to see a Norwegian 
with a transverse cut across the head and through the brain, ex¬ 
tending from one and one-eighth inch above, and one and a fourth 
inch anterior to, the left ear, to a point precisely opposite the tip 
of the right auricle. The cut was made by a band saw bolted to 
the circumference of a horizontally moving circular plane twenty- 
seven feet in diameter, the general appearance and application 
being that of an enormous trephine. The wound was nearly 
eight inches in length, following the contour of the head, and 
seven-eighths broad, scalp and brain being excessively lacerated. 
Above two ounces of disintegrated cerebral substance was re¬ 
moved. The case was very like those already narrated, and sim¬ 
ilarly treated, recovery being complete. Once, suspicious 
symptoms presenting, the lower edge of the wound was freely 
incised, penetratieg the cerebral tissue to the depth of an inch or 
more, and followed by free evacuation of pus. Seven months 
later the patient succumbed to the effects of an alcoholic debauch, 
and a post mortem revealed the brain perfectly healed, normal, 
and without any evidence of disease. 
5. This, reported by Doctor Folsom of California, was a 
wound made by a saw running longitudinally, and extended from 
a point on the frontal bone one-and-one-half inches above the 
nose, to a little to the left and below the occipital protuberance. 
In its course it divided the superior edge of the left parietal. 
Nine inches in length by one in breadth, the depth varied from 
two-and-a-half to three inches. Recovery was perfect, with no 
impairment of mental faculties.

stick seven-eighths square and seven inches long was driven into
