seeking Klemm papers

["Richard F. Lyon" <DickLyon@xxxxxxx>]

Otto Klemm apparently did great work on binaural 
localization, including time-intensity trading. 
But I can't find a clear statement of how small a 
time difference he found to be detectable.  One 
paper says 2 microseconds, but I suspect that's 
wrong.

I have his 1913 and 1914 papers (freely available 
online), but can't find these more important 
later ones:

Klemm, Otto (1918). Untersuchungen uber die 
Lokalisation von Schallreizen. 3. Mitteilung: 
Uber der Anteil des beidohrigen horens. Archiv 
für die gesamte Psychologie, 38, 71-114.

Klemm, Otto (1920). Untersuchungen über die 
Lokalisation von Schallreizen. 4. Mitteilung: 
Über den Einfluß des binauralen Zeitunterschiedes 
auf die Lokalisation. Archiv für die gesamte 
Psychologie, Bd. 40, 117­146.

Does anyone have or know where to find them?
