When the Merck company in Darmstadt provided Sigmund Freud with a gram of cocaine on credit in April 1884, the latter immediately proceeded to try out the effects of the one-twentieth gram dose on himself "during a slight upset brought on by fatigue." Subsequently, Freud not only systematized and "objectified" his experiments by testing the increase in arm muscle strength under the influence of cocaine with the dynamometer and the shortening of mental reaction time with Exner's neuramobimeter; at the same time, cocaine use became a dear habit to him. - Paper somewhat browned. - New half leather binding.
