MICROSCOPE: DR. J. W. EVANS 121 



There are two directions in which we may look for an increase 

 in the demand for instruments of this type. The first is the general 

 adoption by chemists of optical methods of studying crystalline 

 chemical products, and the second, the stimulation of the demand 

 for British instruments in other countries. Every encouragement 

 should be given to those engaged in original scientific work to design 

 new or improved types of microscopes or accessories, and each new 

 type should be fully described in the scientific and technical journals 

 by the inventor, whether he is a member of the staff of a University 

 or of that of an optical factory. If this policy is effectively pursued, 

 other countries will turn to British makers for the supply of instru- 

 ments of the latest and most novel patterns. 



It was by such methods that the well-known German makers 

 obtained the commanding position they held before the war, and it 

 is only on these lines that our country can hope to take the place 

 that it ought to have in the manufacture of specialised types of 

 microscopes. 



The working out of new ideas involves, however, considerable 

 expense, far greater than is afterwards required to construct similar 

 instruments when standardised and produced on a large scale, and 

 it is absolutely necessary that pecuniary assistance should be, in the 

 first place, forthcoming, if success is to be ultimately achieved.
