DISCOVER lies WITH THE MirROSCOPE 217 



of iiiuiiy onlo^cnotic cell ^oiiorations would \)c accounted 

 for. (The writer has already counted the chromomeres, 

 whose number is possibly equal to that of the genes.) It 

 may well be remembered that the genes are not only at 

 the foundation of the theory of inheritance, but also at 

 the basis of any future theory of life itself. 



Utilitarian Discoveries. — There are, no doubt, other 

 important discoveries, made with the achromatic micro- 

 scope, which from the standpoint of applied science, are 

 more important at present than the cell theory or the 

 chromosome theory. Among such are, above all, the 

 discoveries which constitute the science (and art) of 

 bacteriology (including here all microscopic parasites). 

 But these are, in the wTiter's opinion, not sufficiently 

 contributory to the science of biology to be ranked among 

 the few great fundamental discoveries in pure science, 

 however high they deservedly rank in applied science. 



Future Discoveries. — Further important biologcial dis- 

 coveries with the microscope will perhaps come from a 

 triple combination. The method of quickest fixing will 

 have to be combined with the sharpest staining process, 

 and also with the most correct microscopy. Colors of stains 

 should be adapted to the yellow-green (or other) screens 

 in use. Photographs taken with the microscope will 

 doubtless be sharp, if the laws of optics are obeyed as well 

 as they are in the taking of motion-picture photographs; 

 and such sharp photographs wdll perhaps lead to discoveries, 

 as is the case in astronomy. 



These sentences refer to biology, but it seems to the 

 writer that it is in biology especially that many important 

 discoveries with the microscope have been made, and are 

 to be expected in the future.
