100 INTRODUCTION TO SCIENCE 



Science, and only when their work has been fully 

 accomplished shall we be able to realize von 

 Helmholtz's prediction and conceive all scientific 

 formulae, all natural laws, as laws of motion. 

 This goal we must, however, admit is at present 

 indefinitely distant." 



Not only so, but as the only Bio-physics we 

 know of is the physical and chemical study of 

 various processes that occur in organisms, and 

 as no vital function whatever has yet been re- 

 described in bio-physical terms, and as the 

 results of bio-physical analysis do not seem to 

 help us to understand the growth and activities, 

 the development and evolution of living creatures 

 which require interpretations different in kind 

 from those of Physics we are of opinion that 

 Bio-physics might be completed without Biology 

 having more than begun. 



It is greatly to be regretted that an elaborate 

 and vividly clear classification of the sciences by 

 Prof. Patrick Geddes has not yet been published, 

 and therefore cannot be included here, though 

 the most convincing one we know. Some indica- 

 tion of it may be obtained from the following 

 scheme of anthropological studies published in 

 1903 by Prof. A. C. Haddon, for which he was 

 largely indebted to Prof. Geddes: 



EXACT SCIENCE. We have seen that Prof. 

 Karl Pearson has distinguished Precise Physical
