THE MICROSCOPICAL JOURNAL ADVERTISER. 



TWO MICROSCOPICAL JOURNALS 



A Great Change. — From iSSi to 1893 two American micro- 

 scopical periodicals struggled along on the same plane, both 

 fearing continually to lose advanced subscribers by catering to be- 

 ginners, and dreading equally to lose their less advanced patrons 

 because of the matter being too abstruse or " too scientific." Now, 

 the Microscopical Journal will not hesitate to publish the 

 most abstruse contributions to microscopy and biology. It will 

 epitomize the information of permanent value in this science. It 

 will not cater to beginners. The Microscope, on the contrary, 

 endeavors to publish nothing but what everybody can compre- 

 hend, even the 15-year-old boys, of whom several are now sub- 

 scribers, as well as the people, who, while not scientists, wish to 

 learn something of microscopy and to be able to entertain their 

 children with something besides talk. Its matter will often be of 

 temporary interest rather than of permanent value. It is for popular 

 matter. 



How to Begin. — If you know absolutely nothing about a 

 microscope, you can buy a good instrument for from $16 to $30. 

 and by taking The Microscope you can learn how to entertain 

 yourself and friends many a leisure hour. It is one of the most 

 fascinating of recreations. You will need some objects for exhi- 

 bition. See our advertisement of microscopic preparations illus- 

 trating vegetable life at about 5 cents each. Any question that 

 you desire to ask you can get answered in our columns. We 

 also offer the following premiums. 



Premiums. — For every new subscription to The Microscope 

 accompanied with $1 we will give the choice of one of Sutton's 

 slides of American woods. The money must be sent direct and 

 not through any agent for you ,to secure the premium ; other- 

 wise the agent gets the premium. 



Of popular interest ; Ironwood (transverse sectic**" ; Syca- ' 

 more (tr. sec.) ; Spruce (tr. sec). 



Of scientific interest : White pine {Pinus strobus)^ Jong* 

 sec. ; Beech {JFavus sylvaticd) , tr. sec. 



For every new subscription to both The Microscope (price 

 $1) and the Microscopical Journal (price $2) accompanied 

 by $3 we will give one of each of the 5 slides free. Or we 

 will sell either of the slides at 20 cents each, which is the very low 

 price put upon them by Mr. Sutton in his advertisement in the 

 Journal. All subscriptions should end with the volume in Dec. 



New^ Societies. — To encourage the formation of new micro- 

 scopical societies, we will send The Microscope free for one 

 year to ever charter member (not exceeding 15) who participates 

 in the organization. The secretary is to send us a report of each 

 meeting of the society for publication. A model for a constitution 

 and by-laws can be found in The MicroscoPE for May, 1S93.
