This is an atlas, and while auscultation is not discussed, apex cardiography and carotid pulse tracings are included. Several general shortcomings are obvious: (1) The tracings are taken with old equipment, probably of the 1950 vintage. (2) They are all taken with a similar filtration, ie, high-pass filters with slow slope, resulting in a combination of low- and high-frequency vibrations, which is neither scientifically useful nor similar to the response of the human ear.

Such indications had been agreed on and considered essential by international committees from 1950 to 1965. (4) There is a plethora of abbreviations (102). (5) The information supplied in the legends is inadequate for an undergraduate student and fails to give a
