; THE MICROSCOPE. 4! 
E. CASSINO & CO. are soon to issue a translation of Dr. 
- Julius Behren’s work entitled “A Complete Guide to the Use 
of the Microscope in Botanical Research.” [t will contain four 
hundred large 8vo pages, and over one hundred illustrations. 
Every microscopist will await the appearance of the book with the 
keenest interest. We shall offer the work for sale at club rates in 
our future numbers. 
E have before us some of the slide-carriers offered by Milton 
Bradly & Co., in our advertising columns. They are so 
cheap and simple that all of our subscriber’s should send the 
requisite number of stamps for them. 
E notice that at the last meeting of the American Society of 
Entomologists, our Secretary, Prof. D. S. Kellicott, was 
elected President for the ensuing year. In a late number of the 
Canadian Entomologist Prof. Kellicott has an illustrated article on 
the external anatomy of the “Psephenus Lecontet.” 
LEASE remember that all old subscriptions to volume three have 
*now expired and that for eighty cents you can receive our 
journal for the balance of this year. It is only eighty cents to you; 
it is hundreds of dollars to us; it is our success or failure. Please 
show interest enough to renew promptly. We acknowledge all re- 
ceipts of money. Do not send any more stamps, but postal notes 
_ or money orders.
