ROCHESTER MEETING. 
In our next issue we shall have something to say about the 
approaching meeting of the American Society, at Rochester, 
N. Y. We shall then tell just how each member can have a 
copy of the proceedings to read at his leisure in thirty days 
from the date of adjournment. Wemay be rash enough to 
state that it is to be hoped the whole society will not become 
buried in diatomaceous material. 
We may ask if the criticism of ‘‘ Science ” is just, when it 
said in its issue of April 11th., that the twenty-six papers ‘ are 
mostly by amateurs, and show it, for the most part, more 
plainly than is consonant with a high scientific body.” This 
wonderful periodical further states that “there is not more 
than a single communication which appears to be the result of 
a serious and prolonged research by an experienced investi- 
gator.” 
Bnt our ideas on this subject will appear in due time. 
OE — 
While we shall make a special effort to have our next num- 
ber present the interests of the American Society, yet in the 
meantime we hope many of our readers will prepare live, prac- 
tical questions and papers for the meeting of that body. 
Let us realize in these young days of microscopical science 
that the question is not “ how much of microscopical literature 
have we at command ” as it is ‘“‘ How perfect are our methods 
of work ?”

NEW APPARATUS. 
We have seen lately two very fine pieces of apparatus. 
The one is a self-centering turn-table, the invention ot Mr. E. 
H. Griffith. The junior editor accepts the gift with becoming 
modesty. A prominent microscopist said to us a few days ago 
that “turn-tables were only good to throw at cats,” but we fear 
there will be trouble in our family if he should ever come West
