THE PRIVILEGES AND RESPONSIBILITIES 
OF THE CHEMICAL ANALYST* 
In his presidential, address on ‘‘ The Dig- 
nity of Analytical Work,’’ delivered before 
the American Chemical Society in 1897, 
Dr. Charles B. Dudley directed attention 
to the claims which may be asserted in be- 
half of analytical chemistry as an impor- 
tant and dignified branch of chemical sci- 
ence, and the necessity for intelligent, 
careful work on the part of even the 
routine analyst. From a somewhat differ- 
ent standpoint, Dr. W. F. Hillebrand, of 
international reputation as an analyst, pre- 
sented at the Philadelphia meeting of the 
Society, in 1904, a critical review entitled 
“Some Thoughts on the Present Condi- 
tions of Analytical Chemistry,’’ which was 
based upon his experience as chairman of 
committees intrusted with the formulation 
of standard methods of analysis and the 
investigation of the causes for the remark- 
able variation in the results of different 
analysts examining a given sample of ma- 
terial. He sounded a definite and clear 
note of warning with respect to the prev- 
alence of a lack of care and intelligence, 
and ascribed the conditions, in part at 
least, to faulty training in our educational 
institutions. Within the past month there 
has appeared an interesting brochure from 
the pen of Dr. Wilhelm Bottger, professor 
at the University of Leipzig, entitled 
“‘Der Stand und Wege der Analytischen 
Chemie,’’ in which he criticizes the too em- 
pirical nature of much of the analytical
