I. SUMMARY OF LABORATORY WORK. 
While a statement of the number of determinations of different 
kinds does not include an account of all kinds of laboratory work 
and does not, therefore, necessarily convey an accurate idea in 
regard to the whole amount of laboratory work done, nevertheless, : 
it serves to give fairly adequate information in regard to the 
extent, character and variety of the chemical and allied work. It 
will be noticed that our chemical work has been mainly confined 
to two lines, investigations connected with dairy problems and 
analysis of fertilizers,
