Dr. Palmer noticed that the janitor, Harvey Lillard, who worked in his building, was nearly deaf. Dr. Palmer inquired about the cause of his deafness and was informed that when Harvey was exerting himself in a cramped, stooped position, he felt something give in his back and immediately became deaf. Harvey had been nearly deaf for 17 years.
Dr. Palmer decided to examine Harvey. Upon examination, he noticed a bump, which he determined to be a spinal vertebrae out of position. Harvey said he noticed this bump right after he lost his hearing.
