During the coming year, the microscope will continue 

 and expand its popular features. People not accustomed 

 to the use of these instruments will be able to appreciate 

 pictures of invisible life. Arrangements have been made 

 to illustrate each number in the style of the present is- 

 sue. Dr. Shanks will continue the Replies to Queries, 

 and each subscriber will be privileged to submit 10 ques- 

 tions. Mr. Willson will continue the Practical Sugges- 

 tions. Dr. C. Q. Jackson of Pittsburg has accepted the 

 Department of Science-Grossip. Whatever will tend to 

 increase popular interest in the Microscope will receive 

 our cordial support.
