per cent of fat (15) in skim-milk as determined by analysis, an 
(16) in cream; total fat (17) in skim milk, and (18) in cream; 
percentage of fat (19) recovered in cream, and (20) lostin skim milk. 
The experiments represented by each series are repeated at Hi 
least three times. If the results do not all agree, work is con- 
tinued until the cause of lack of agreement is found and obviated, i. 
if possible. iis 
It is proposed to repeat the same series of experiments, using — 
the same degree of dilution but varying the temperature of the ks 
water added until a wide range of temperatures is tried, and, per- — 3 
haps, making other variations. Then the amount of dilution and — 
the same range of temperatures are gone through as before. 
The plan proposed involves an enormous amount of work, but | 
it is desirable that the ground should be covered so Mie ; 
that some definite results may be reached. “ 
Up to December first, eighty-one experiments were made, _ 
nearly covering the ground relating to dilution by adding two 3 
pounds of water at 35° Fahr., and at 130° Fahr. free to eight — 
pounds of milk. 
Inasmuch as this constitutes only a beginning of the work, the 
detailed data of the experiments will be reserved for publication 
until later, in a bulletin, when the investigation shall have covered _ 
more ground. | 
VII. INVESTIGATIONS ENTERED UPON AND Lines oF WorK PLANNED. 
All the lines of work previously noticed in this report will be 
continued during the coming year. In addition to these investi- — 
gations, others have been entered upon but are not yet carried 
far enough to report upon. These additional investigations haye 
reference to methods of analysis. 3 
It is hoped that time may be found during the coming year ial a 
carry on a series of feeding experiments in order to study the ~ 
effects of certain foods upon the yield of milk and butter, as 
regards both quantity and composition. ; ae 
So far as time permits, the Station will heartily co-operate in ~ 
carrying out the work of the Association of Official Agricultural — : 
Chemists, in analyzing for the reporters of the association such a 
substances as are especially connected with our work. To a cer- 
tain extent, the work of the Station can not be more proitebias 
employed than in aiding in the improvement of methods of 
analysis. |
