The head-rest which I wish to present was designed by Dr. Hasslinger in Hajeck's Clinic in Vienna. While working in this clinic, I was much impressed with the advantages of this ingenious device and brought one home for further study (fig. 1).

A B Fig. 2.—Head-rest in two positions.
When one depends on an assistant to hold the head in a uniform position by use of the hand alone, the head is often unsteady and the soft parts of the neck unrelaxed. Again, it may be impossible to obtain the services of a trained assistant, in which case the operator may bring the head in any desired position for a prolonged period by means of the movable head-rest.
With this new device, it is not only possible to retain the head and cervical spine in marked dorsoflexion, but the elevation can be changed to any desired position
