ation with Professor John O. Reed 1902, 1907; "Laboratory Exercises,"
1903; "Heat" in Blakiston's text book 
of Physics, 1908; and over forty arti
cles on physics in scientific journals. Among the more recent of which 
are "The Silver Coulometer, 1905; 
" E.M.F. of Weston and Clark Standard Cells," 1906; "Das elektrochem
ische Aequivalent des Silbers," 1906; 
 "Experiments on Heusler's Magnetic
Alloys," 1906; "Photoelectric Proper-
ties of Selenium Cells," 1907; "Standard Cells," 1907; and "Peculiarities in 
the Elastic Properties of Certain Substances," 1908.

Professor Guthe is 
also a member of Sigma Xi and the
 American Association for the Ad
vancement of Science, of which he is
 vice-president and chairman of the 
physics section. He is also member of 
the Committee on Physics in two
 other Associations, a member of
