Two men were told to grasp the feet and two more the head, and were directed to make careful but strong extension.

At the same time the physician placed his right hand against the neck just over the pomum Adami, and his left against the occiput, and, while extension was being made, he flexed the head forward until the chin nearly touched the breast, after which the head was returned to its normal position.

The manipulation was accompanied by a clicking sensation, caused by the replacement of the dislocated vertebra.

The patient immediately showed signs of relief and improved rapidly.

Perceptible but feeble movements were made by all the limbs except the right arm.
