A 1873 manual to cure stuttering
Eduard Günther. Praktische Anleitung zur vollständigen Heilung des Stotterns für Eltern und Lehrer sowie zum Selbstgebrauch. von Ed. Günther, Hauptlehrer der Taubstummen-Anstalt zu Neuwied. Neuwied & Leipzig, Druck und Verlag der J.H. Heuser'schen Buchhandlung, 1873. 22,5 x 15,5 cm. , X, 127,  pp. Original printed boards (the back with a publisher's stocklist). Paper browned, boards with some wear, otherwise in very good condition.
First edition of a German manual to cure stuttering, by an author who established an institute for deaf-mutes in Neuwied (Germany) in 1854.
The first two pages include favourable reviews of Günther's method, then follow a brief preface and 50 exercises in a fascinating design that resembles avant-garde poetry of the interbellum. The manual was apparently rather successful: it was reprinted in 1888 and 1893; this first edition, though, is surprisingly rare.
