Unlabelled:
The author publishes the results of examining the hands of 100 old subjects. The paper contains the impressions obtained by inspection and palpation (i.e. by non-invasive procedures) on the parallel nature of the senile degenerative symptoms and the psychosomatic status of the old subject.
Control:
examination of the hands of 100 middle-aged persons. It has been found that a pathological symptom absolutely typical and specific of old age cannot in itself be evaluated, but the simultaneous presence of a number of degenerative cases points to the biological aging of the chronologically old subjects. The subjects of inspection are: turgor of the skin of the hand, finger-nails, pathological pigmentations, vascularization under the skin, muscular atrophy, arthritic changes and hand tremor.
