[Measuring of the human body with the "Differentiometer" (author's transl)].

The "Differentiometer" is a handy instrument suitable for many measurements of the human body. Many important parts of the human body in their length, in their geometrical position and in their relation to each other can be measured on the lying as well as on the standing patient. Some of these measurements could not be done clinically until now. With these measurements investigation by X-ray sometimes can be spared.
