annoyed at the correction, but we went 
to press a week earlier than usual—in 
fact a day or two before your letter 
came. You will remember it was 
Christmas week. 
H. A. R.—We would rather not 
express any opinion upon the subject 
of your letter. Try both naturalists. 
A, A. C.—We think the least you 
could do, if you wished your letter 
forwarded, would be to enclose a 
stamp. 
T. B. K.—The matter will be under 
review next month, and then you will 
be able to judge whose was the prior 
instrument. 
J. C. C.—We shall be glad to receive 
the copies of Nos. 1 and 4 of THE 
NORTHERN MIcrRoscorisT you offer ; 
full price will be paid for both. 
B. T.—The aperture shutter has 
been used successfully in photo-micro- 
graphy, especially for high powers. 
Dancer or Collins will supply you. 
H. G.—We shall return you the 
transparencies in a few days; they are 
very clean for gelatine plates. 
A. P. Y.—See last year’s volume for 
the terms and conditions of the verifi- 
cation department. We cannot add to 
our labour in the direction you wish,
