 ette Station." 



Mr. Holman made an oral communication in relation to a 

 new microscope, lately invented by him, by which objects dis- 

 tant from its front lens over two and a half feet could be 

 readily examined in their habitat. For example, at that dis- 

 tance a salamander of a few inches in size would appear some 

 thirty inches in length, and its whole circulation of blood 

 would be plainly visible. The instrument uses a photographic 

 lens as an object glass, and is really a short-focus telescope. 



Pending nominations Nos. 1220 to 1229 (inclusive) were 

 read.
