lg l Here follow the more important chemical analyses and inves=  
W, tlgations made in the Station laboratory during the year 1892,. ll* ‘
but not published in a.ny of the Bulletins. The work already  
m published is mainly fertilizer control work in Bulletins 41 and  
Of 43 ; some work on marls, in Bulletin 39 ; and the usual work in· l yi  
he connection with the study of methods of analysis by the Asso- `  
YQ? _ clatlon of Official Agricultural Chemists, and to be found in  
their proceedings. .  
BH, A number of analyses of commercial fertilizers have been  
,H_ made for farmers, but, being only of temporary interest, it is  
li, not thought necessary to publish them here. As a rule, as  
heretofore, the fertilizers sold to farmers and sent in by them A  
for analysis have, in most cases, come up to the required  
Daily tests of the milk of the Station cows have been made,  
and a large mass of figures is accumulating from which inter-  
esting results may be derived at some future time. _  
A number of rocks and minerals have been identified for  
various persons, and several analyses of potable water were- fFji°¥{.;i
made, which it is not thought necessary to report in detail.  
Butter.   {pj
A number of samples of butter made from milk of the Jersey  
Cows " Signal Ripple" and ··Jus·a Pogis," at the Station farm    
have been analyzed, The manipulation was as uniform as pos-   f
Bible, and the results show the difhculty of obtaining perfect  
uniformity in the product under ordinary conditions, as well as    
the difficulty of correctly sampling a small amount of butter.
