take extensive prehistoric studies in Asia 

 Minor and in the region of the Caucasus. 

 His studies in prehistoric archeology, which 

 apparently are so remote from his original 

 anatomical work, are in reality closely con- 

 nected with his researches on the early his- 

 tory of the races of Europe. Anatomical 

 data alone cannot solve these intricate prob- 

 lems, and Virchow's extensive activity in 

 the field of prehistoric archeology is anoth- 

 er proof of his thorough and comprehensive 

 method which utilizes all the available 

 avenues toward the solution of a scientific 

 problem. 



Physical anthropology and prehistoric 

 archeology in Germany have become what 

 they are largely through Virchow's in- 

 fluence and activity. His method, views 

 and ideas have been and are the leading 

 ones. His greatness as a scientist is due 

 to the rare combination of a critical judg- 

 ment of greatest clearness and thorough- 

 ness with encyclopedic knowledge and a 

 genius for grasping the causal relation of 

 phenomena. His critical judgment was so 

 strong that, in an address delivered in the 

 summer of 1900, he was even led to doubt 

 the desirability of the strong preponder- 

 ance of his influence upon current opinion. 

 "With profoi;nd admiration and gratitude 

 we regard his life's work which has deter- 

 mined the course of a new science.

SCIENTIFIC RESEARCH: THE ART 



OF REVELATION AND OF 



PROPHECY, II. 



XI. 



Collaboration of all sciences, physical 

 and metaphysical, must ultimately be the 

 task of the investigator and the end of 

 research. The several sciences are the 

 formulated expressions of nature's law of 

 a universe, and all are functions of force, 

 movement, energy, of life and its material 



foundations. To discover the relations of 

 the sciences and to reduce them all to de- 

 partments of one all-comprehending system 

 will prove, if it can be achieved, the highest 

 result of research. Already, the thermal, 

 luminiferous, electrical, mechanical, chem- 

 ical, and to a certain extent the biological, 

 sciences are known to be divisions of the 

 more comprehensive science of energetics; 

 all treat of manifestations of energy and 

 its conversion from form to form and its 

 transfer from point to point. Already it 

 is known that other manifestations of force 

 and energy, if not still-disguised illustra- 

 tions of familiar forms, are existent in 

 the animal machine, and it is suspected by 

 some, believed by others, admitted to be 

 possible by yet others, that those energies 

 which pervade the more ethereal atmos- 

 pheres, the vital and perhaps other ener- 

 gies, are transformations of the familiar 

 kinds. The question has even been seri- 

 ously and honestly asked whether spiritiial 

 life and energies may not have definite 

 relations of quantity, and even of trans- 

 form ability, with those characterizing the 

 physical world. Vital energy, moral force, 

 the efforts of genius, exhibit themselves in 

 the individual in larger or lesser degree as 

 his supply of potential energy in form of 

 food varies from excess to deficiency and as 

 his physical powera fluctuate. 



Are there two universes, the seen and the 

 unseen? How is the seen related to the 

 unseen? Are there deflnite quantitative 

 equivalences among the forces and the 

 energies of the one and of the other? 

 Wliat are these equivalences among the 

 energies of, the unseen, if they exist, and 

 what the facts and laws, the algebraic state- 

 ments of law, and the values of the con- 

 stants representing facts at the points, the 

 surfaces, of junction? 



These and other questions constitute 

 problems for the coming investigator, fa- 

 miliar with the phenomena of the seen and
