ANNOUNCEMENT. 



These Science Studies of the Montana Agricultural College are in- 

 tended to afford a medium for the publication of papers dealing es- 

 pecially with pure science and general education, and are co-ordinate 

 with the bulletins of the Agricultural Experiment Station, which 

 consider the subject of science only in its economic aspect. The 

 two phases of pure and applied science are so closely interwoven that 

 any careful work in one usually necessitates the accumulation of 

 more or less data in the other, for the publication of which these 

 two parallel series are necessary.
