THE AMERICAN 

 JOURNAL OF MICROSCOPY, 



POPULAR SCIENCE. 



PROSPECTUS. 



The object of the JOURNAL OF MICROSCOPY is to diffuse a knowledge of the 

 best methods of using the Microscope; of all valuable improvements in the in- 

 strument and its accessories; of all new methods of microscopical investigation , 

 and of the most recent results of microscopical research, 'ihe JOURNAL does 

 not addiess itself to those who have long pursued certain special liues of re- 

 search, and whose wants can be supplied only by elaborate papers, which, from 

 their thoroughness, are entitled to be called monographs rather than ruere arti- 

 cles. It is intended rather to meet the wants of those who use the microscope 

 for purposes of general instruction, ai d even amusement, ard who desire, in 

 addition to the infoimation afforded by text-books, such a knowledge of what 

 others are doing as can be derived only from a periodical. "With this object in 

 view, therefore, the publishers propose to make the JOURNAL so simple, practical 

 and trustworthy, that it will prove to the advantage of every one owning even a 

 pocket magnifier to take it. 



ILLUSTRATIONS. The JOURNAL will be freely illustrated by engravings 

 representiig either objects of natural history or apparatus connected with the 

 microscope. 



EXCHANGES. An important feature of the JOURNAL is our exchange column, 

 by means of which workers in different parts of the country are enabled, with- 

 out expense, except for postage, to exchange slides and materials with each other. 



TZEIFLJVEJS. 



In order to bring the AMERICAN JOURNAL OP MICROSCOPY within the reach of 

 every one, the subscription rate has been made very low 



FIFTY CENTS PER YEAR. 



To those who send three subscribers we will Bend an extra copy free. Those who 

 desire to obtain the JOURNAL WITHOUT COST, can do BO by sending us the regu- 

 lar subscription price for any journal or magazine, in which case we will send the 

 periodical ordered and the JOURNAL OF MICROSCOPY too. There may be a few 

 cases in which we cannot do this, but they are very rare. The postage on copies 

 sent to Europe, however, is such that there are many cases in which we cannot 

 extend this privilege to our foreign subscribers. 



All subscriptions are payable in advance, the rate being too low to warrant us in 

 opening book accounts. 



SUBSCRIBERS IN GREAT BRITAIN. The JOURNAL will be sent, postage paid, 

 for 2s. 6d- per year. English postage stamps, American currency or American 

 postage stamps taken in payment. In return for a postal order or draft for 1 Is., 

 eleven copies of the JOURNAL will be furnished and mailed to one address. Make 

 all drafts and postal orders payable to John Phin. 



VOLUME I. BACK NUMBERS. We have on hand a few copies of Tol. I., bound 

 in hai dsome cloth cases, which we offer for $1.25. We cannot eupp'y complete 

 sets in sheets, but can furnish any numbers, except NOP. 1 and 4, for four cents 

 each. For clean copies of Nos. 1 and 4 we are willing to pay 8 cents each. 



The JOURNAL OF MICROSCOPY, from its very nature, is a visitor to the very 

 best families, and its value as an advertising medium has therefore proved to be 

 much above that of average periodicals. A few select advertisements will be 

 inserted at the rate of 30 cents per line, nonpariel measure, of which twelve 

 lines make an inch. Address
