SEPARATES. 



One hundred separates of 

 each original paper accepted 

 are furnished the author, 

 gratis. Separates are bound 

 in special cover with title. 

 A greater number can be had 

 at cost of printing the extra 

 copies desired. 



The science teacher who has not provided himself with some sort of camera 

 and has not learned how to make good reproductions of objects with it is depriv- 

 ing himself of one of the surest means of teaching his subject successfully. Next 

 to the object itself, nothing is so satisfactory as an actual photograph. Descrip- 

 tions and drawings are necessary, but they are more or less inaccurate and cannot 

 give the student the clearest conception of the object. Not many schools are 

 provided with a working museum or herbarium, but the camera in the hands of any 

 teacher is the means of bringing a great many things to the attention and interest 

 of students that would otherwise be unavailable. Field work with classes is more 

 or less expensive and time consuming, and therefore cannot always be indulged in 

 to such an extent as to be very beneficial. The habits of plants in their native 

 haunts, differences in form of different species, differences in form of the same 

 species under different conditions, differences at different stages of development, 

 at different times of year, and numberless other interesting and instructive obser- 

 vations that cannot be brought to the class-room in any other way, may be 

 recorded and presented almost as forcibly as though the students were taken to 

 the field, and with far greater comfort and saving of time. The same is true of 

 every other branch of science teaching. 



With a camera one can soon accumulate a collection of illustrations from 

 different localities that will be of no small value. 



To do this does not require a great outlay. The better the tools the better 

 the results, but even with an inexpensive box camera one may record observa- 

 tions that will be found exceedingly useful. 



Not the least benefit derived from such elementary work is the introduction 

 to the methods of general photography, and, what is more important, photomicro- 

 graphy, a subject now indispensable in every microscopical laboratory. 



The editor has had the pleasure during the past month of forwarding the 

 applications of a number of our readers to the secretary of the American Micro- 

 scopical Society, and would be glad to forward information to any others who 

 would like to be affiliated with this, the only national society for the improve- 

 ment of the microscope and the encouragement of original research in this field. 

 The American Microscopical Society has been organized twenty-three years, 

 and is worthy of the support of all interested in the advancement of laboratory 

 practice.
