The author reviews recording techniques as used in physiologic and clinical experimentation. There are ten chapters. They extend from a description of a simple kymograph, a photocell, a flow-meter, and a plethysmograph to electronic equipment. They include electrocardiography, electroencephalography, and the various means of producing electric stimulation of biologic objects.
In about 200 pages the treatment of so many apparatuses and their application is, of course, brief and cursory. However, the book will serve well as a source of basic information. The language is simple and clear. References are almost entirely German.
