Dear Sir : 



At the close of the present year we shall discontinue the 

 publication of the American Monthly Journal of Microscopy, but 

 in its stead we would call your attention to Science Record, a monthly 

 journal of scientific notes and news, in which all that relates to the Mi- 

 croscope, its use and its discoveries will occupy a prominent position. 

 Especial attention will be given to microscopical technique, including 

 descriptions of improvements in staining, section-cutting, mounting and 

 hints concerning the management and use of this important instrument. 

 All theoretical questions of little practical importance and less popular 

 interest will be omitted. 



Besides the IMicroscopical department. Science Record will strive 

 to give in a concise form and in popular language the scientific news 

 of the world, including, besides the important discoveries in all depart- 

 ments of science, personal notes, answers to correspondents, editorial 

 notes and reviews, and notices of books, papers and periodicals received. 

 Illustrations will be used when necessary to as large an extent as the 

 subscription list will warrant. 



The editorial management will be in the hands of J. S. Kingsley 

 of Maiden, Mass., and to him should be sent all exchanges, books and 

 papers for review as well as all correspondence relating to the literary 

 portion of the journal. Mr. Kingsley will be aided in his labors by 

 several of the prominent scientists of America and every care will be 

 taken to render the paper newsy, readable and reliable. 



A sample copy is sent you to-day. The subscription price is One 

 Dollar a year, payable in advance, and we hope to enter you upon our 

 lists. 



We are yours very truly, 



S. E. Cassino & Company.
