THE EVOLUTION OF THE SCIENTIFIC 

 INVESTIGATOR.* 



Among the tendencies characteristic of 

 the science of our day is one toward lay- 

 ing greater stress on questions of the be- 

 ginning of things, and regarding a knowl- 

 edge of the laws of development of any 

 object of study as necessary to its complete 

 understanding in the form in which we 

 find it. It may be conceded that the prin- 

 ciple here involved is as applicable in the 

 broadest field of thought as in a special 

 research into the properties of the minutest 

 organism. It, therefore, seems meet that 

 the comprehensive survey of the realm of 

 knowledge on which we are about to enter 

 should begin by seeking to bring to light 

 those agencies which have brought about 

 the remarkable development of that realm 

 to which the world of to-day bears witness. 

 The principle in question is recognized in 

 the plan of our proceedings by providing 

 for each great department of knowledge a 

 review of its progress during the century 

 that has elapsed since the great event which 

 the scene around us is intended to com- 

 memorate. But such reviews do not make 

 up that general survey of science at large 

 which is necessary to the development of 

 our theme, and which must include the 

 action of causes that had their origin long 

 before our time. The movement which 

 culminated in making the nineteenth cen- 

 tury ever memorable in history is the out- 

 come of a long series of causes, acting 

 through many centuries, which are worthy
