AND SUPER MICROSCOPE 



enlarged by the original microscope. In other 

 words, the power of one microscope is employed on 

 that of another. 



The apparatus as we have described it gives 

 enormous magnifications and it is possible, by using 

 a suitable combination of objectives, to obtain a 

 magnification of ten thousand diameters. Ex- 

 pressed in non-technical language, a circle whose 

 actual diameter is equal to the thickness of the 

 paper upon which these words are printed, could be 

 so magnified by the super-microscope that it would 

 appear to be as thick as ten thousand similar 

 pieces of paper but, with this enormous magnifica- 

 tion, it is obvious that, even with such a marvellous 

 instrument, the whole of the circle from edge to 

 edge could not be seen at one time. With an ordi- 

 nary microscope a magnification of one thousand 

 three hundred diameters is considered highly satis- 

 factory. So that there is a great probability of 

 being able to see some of the minute objects which 

 are known to exist, but which have, up to the 

 present, eluded those who would view them, on 

 account of their minuteness. There is a possibility 

 also of discovering a new underworld of which no 

 man has yet dreamed. The man who uses his micro- 

 scope solely because of the pleasure he derives from 

 it, rather than he who uses it because it is essential 

 to his business or profession, will be more attracted 

 by the micro-telescope. By this we do not infer 

 that the instrument is not useful, as a fact it is of 

 the greatest importance in certain cases, especially
