ARTIFICIAL LIGHT. 201 



an absurd attempt to display the hateful markings ; an 

 attempt, too, as futile and puny as that of the child who 

 cries for a piece of the moon. And why? Simply be- 

 cause the object-glass employed is not suited to the work 

 in hand. Nor is the picture overdrawn, as more than 

 one lady can attest, or the " looker on in Venice " 

 vouch for. 



To all such, to all who value the microscope as an aid 

 to scientific investigation, let me urge the importance 

 of studying well the nature, capacity and capabilities 

 of the objective, and to this end, and in the special line 

 we have been discussing, the Wenham "reflex" will 

 prove itself a valuable and important accessory, and a 

 time saver of the very first water.
