Present and Future Conditions. 



The field to be occupied by the "American Journal of 

 Science and Arts/' as seen by its founder in 1818 and 

 presented by him in the first number, as quoted entire on 

 an earlier page, was as broad as the entire sphere of 

 science itself. It thus included all the departments of 

 both pure and applied science and extended even to music 

 and fine arts also. As the years went by, however, and 

 the practical applications of science greatly increased, 

 technical journals started up, and the necessity of culti- 

 vating this constantly expanding field diminished. It 

 was not, however, until January, 1880, that "the Arts" 

 ceased to be a part of the name by which the Journal 

 was known. 



About the same date also — or better a little earlier — ■ 

 began an increasing development of scientific research, 

 particularly as fostered by the graduate schools of our 

 prominent universities. The full presentation of this 

 subject would require much space and is indeed unneces- 

 sary as the main facts must be distinct in the mind of the 

 reader. It is only right, however, that the large part 

 played in this movement by the Johns Hopkins Univer- 

 sity (founded in 1876) should be mentioned here. 



As a result of this movement, which has been of great 

 benefit in stimulating the growth of science in the
