THE MICROSCOPE. 149 



" As a microscopist of 20 years, let me say that your editorial in 

 reply to Mr. Hitchcock is none too severe. Your journal is appreci- 

 ated by practical microscopists." 



" While I respect Mr. Hitchcock's ability, I regret the course he 

 has taken." 



Two of the above letters were from experienced editors of very 

 prominent scientific journals. 



Within the past ten days, a man " who is acquainted with nearly 

 every medical and pharmaceutical journal in the courtry," says: 

 " If the success of The Microscope in a financial sense at all 

 matches its literary style, I must congratulate you upon a 'strike' in 

 the field of periodical journalism." 



An advertiser in Mr. Hitchcock's journal, under date of Novem- 

 ber 3d, says: "Your journal is a bright, earnest sheet, and in the 

 direction of practice rather than theory. There is plenty of room 

 for your journal." 



Mr. Hitchcock ridicules us for calling attention to Dr. Hahn's 

 discovery. He calls it "sensational and highly improbable; not 

 deemed sufificiently authentic to deserve mention in these columns." 

 We reply by asking " What does the Royal Microscopical Journal of 

 London say about it ?" " What does Science say about it ?" 



Mr. Hitchcock is older than we are; has had experience in jour- 

 nalism; has written and said much on the theory of the microscope; 

 yet, notwithstanding this, we have added nearly 100 paid subscrib- 

 ers to our list since our October issue, and before this journal 

 reaches the reader the number will be largely increased. It is the 

 "familiar, colloquial style" that does it. The busy physicians and 

 pharmacists desire practical help, not theoretical. It is for this rea- 

 son that the first edition of our Histology was exhausted in less 

 than six months after its appearance, a revised second edition being 

 in press now. 



In conclusion, Mr. Hitchcock, we cordially invite you to give 

 us a visit. Our 400 students who study microscopy each year under 

 our supervision, will welcome you. We will show you over 100 com- 

 pound microscopes. You may use our immersions; we have a \, J, 

 -jJg-, ^g-, J^, and -Jjj-. We will show you specimens mounted by our 

 students, forming a part of their yearly total of 7,000. We will show 

 you as fine drawings of microscopical specimens, for .students' work, 

 as you have ever seen; and we will study over our test diatoms and 

 ruled plates as long as you may desire.
