PROCEEDINGS OF SOCIETIES. 31 



lensos I may add the following remarks. Worked with their im- 

 mersion fronts, I regard the ^ths and ^\ths above mentioned as 

 superior in defining power to the dry ^V*^ ^^^ Tcr*^ ^^ *^^ same 

 makers. This is shown on test-objects, such as the AmpMpleura 

 pellucida, &c., and on anatomical preparations, as well as on the 

 Nobert's plate. The immersion objectives in question combine, with 

 exquisite defining power, unriveUed flatness of field and depth of pene- 

 tration. In all these qualities the two immersion yV*-'^^ excel any 

 objectives it has been my fortxme to obtain from any source. I make 

 this statement with pleasure, out of justice to the makers, with whom 

 I have no personal acquaintance. I should take still greater pleasure 

 in being able to announce that I had obtained from them, or from any 

 other makers, still better objectives. 



Very respectfully, 



J. J. Woodward, U. S. Army.

 i^laa diameter, the same as those of the small so-called " moose deer" 

 of Ceylon.
