THE MICROSCOPE. 169 



DR. FELL'S paper has awakened .some of the sleeping brothers 

 and he has been "criticised." The cause will not suffer by it 

 neither will Dr. Fell. 



THE first official document from the office of the president of the 

 American Society has reached us. It gives the list of new 

 officers, and urges all members to keep alive to the interests of 

 American Microscopy. We notice at the head of President 

 McCalla's last letter that he had then written eighty-four official 

 letters. Let us all do our share toward making the Chicago meet- 

 ing a success. 



MRS. STOWELL gives a paper before the "Michigan State 

 Teachers Association," December 28th, on "The Microscope 

 in our Public Schools." 



HOW convenient it is! Webster, Klein and Smith are now 

 easily handled. All because L. W. Noyes invented his ingen- 

 ious holders. They are an ornament as well as great convenience.

A LETTER from Mr. Walmsley bearing date of November 14,, 

 says that his article will "surely be ready for the February 

 issue." 



G. A. Vicker's method for killing and preserving insects: 

 " Place a drop of the acid (pure crystallized with just sufficient 

 water added to keep it fluid) on a slide and drop into it the living- 

 insect; it will be seen to struggle for a second or two, then the limbs, 

 wings, and tongue become extended; it then becomes beautifully 

 clear and transparent. The acid should now be drained away, a 

 drop of balsam put on, the cover applied. — Northern Microscopist. 



Dr. Klein has been testing the value of Pasteur's "vaccin char- 

 bonneaux" and declares it a failure. He also thinks the fluid dan- 

 gerous, introducing the anthrax where it does not exist.
