The. past history of SCIENCE is a sufficient guarantee of its future 

 usefulness. Such a Journal is essential to the advance and proper recognition 

 of the scientific work of each country, and in America, where men of science are 

 scattered over a great ar^a, with no single center for personal intercourse, it is 

 peculiarly needful. With the growth of science and scientific institutions in 

 America SCIENCE will occupy an even more important position than at present. 

 It will continue to set a standard to the popular press in its treatment of scien- 

 tific topics, to secure that general interest in science so essential to its material 

 support, to enlarge the place of science in education and in life, and to demon- 

 strate and increase t.ie unity of science and the common interests of men of 

 science
