Further experiments brought about individual discoveries by the co-author and by Captain William E. Amos, MC, U.S. Army, Resident, that the vibra-puncture technique could be carried out with a minimum of discomfort and no visible epidermal alteration when the motor was operated at a very low speed.
Despite the most conscientious efforts on the part of the operator, attempts to obtain constant low motor speed
