read and discussed at the time designated—also that the Pub- 
lishing Committee may select such as they may think best for 
publication. Veterans in any work, especially in Microscopy, 
are often asked simple questions which they are unable to an- 
swer, and amateurs often desire information which they have 
been unable to find in books. No name will be read in connec- 
tion with the communication,and it is earnestly desired that prac- 
tical questions, no matter how simple, will be sent in at once. 
If you wish to know what is meant by the standard length of 
tube—whether a large tube is better than a small one—why an 
object seen through an objective on one stand looks clear, 
and hazy when used on another; how to measure angle of ap- 
erture; how to determine the quality or the power of an ob- 
jective or an ocular; how to sharpen your section cutter; or 
how to cut certain sections; how and when to secure certain 
kinds of microscopical material; or if you desire for yourself, 
or for the benefit of others, information of any other kind, please 
sit down at once, write the questions and send them in.

preparations and will do much toward retaining our reputation 
for hospitality. . 
The Powers Hotel, than which few exist in this country 
with better accommodations, has been fixed upon as headquar- 
ters. The spacious parlor has been reserved for the Reception 
Committee, and visiting members will be favored with reduced 
rates. The First Baptist Church, situated almost directly oppo- 
site, has been offered for the place of meeting and two large 
rooms in the same edifice will be arranged for exhibition pur- 
poses. The Corinthean Academy of Music will probably be 
retained for the President’s address. The drill hallof the State - 
Arsenal, the largest by far in the city, will be used for the
