Augsburg: ERV Dr. Erwin Rauner Verlag (ISBN 978-3-936905-23-6/pbk). Algorismus 60, 59-68 (2007). The author studies the position of the German geometer Eduard Study (1862-1930) with respect to exactness in geometry. It was at the time not unusual to discuss merely the ‘general case’ without paying attention to exceptions. The author discusses among other examples Study’s very critical opinion of Felix Klein’s “Lectures on Higher Geometry”For the entire collection see [Zbl 1123.01002].
