Abstract
Apparatus for measuring the firmness of tissue, for example of skin in vivo, comprises a compartment open at one end and having a deformable bulb at the other end to allow the compartment near the open end to be subject to internal suction deforming a portion of skin against which the apparatus is applied to dome upwardly into the compartment. A plunger pressed upwardly by the doming skin actuates a pivotable pointer visible from outside the apparatus.
