[418] On p. 18 of his treatise he goes so far as to say: “There is no disease of the body or the mind which cannot be referred to masturbation.”
[419] Eulenburg refers also to “Persönliche Schutz,” by Laurentius; the “Jugendspiegel,” by Bernhard; the “Johannistrieb,” by B. Mohrmann; the “Krankheit der Welt,” by A. Damm.
[420] According to A. Jacobi (“The History of Pædiatry, and its Relation to Other Arts and Sciences,” p. 66 (Berlin, 1905)), this is not true of quite young children, at ages of from one to ten years, in whom masturbation does less harm than in half-grown or adult individuals.
