11-^0 Journal of Applied Microscopy 



With the beginning of our fourth 



journal or volume the scope of the Journal is 



Annlicd I^icrOSCOnV broadened so as to include general 



a„j laboratory methods in those branches 



Laboratory Methods. ^^ science and industry in which the 



microscope is used.

curiosity shop to a substantial aid in 

 demonstration, just as the microscope has been elevated from the function of 

 a toy to that of the biologist's right hand assistant. 



The camera, popularly employed for recreation, now supplies one of the 

 readiest, most useful and reliable means for illustration and the recording of 

 facts and conditions. 



The stereopticon has advanced from the companionship of children to the 

 control of the lecture room. 



The countryside with its ponds and ditches, once the exclusive territory of 

 the naturalist, sneered at by the section cutter, is again sought by biologists, and 

 without a knowledge of the life of its denizens his work is balked. 



So through the list the index points to a Journal of Applied Microscopy 

 AND Laboratory Methods in which the microscope shall be the principal sub- 

 ject and the related methods be given their proper share of consideration. 

 In this decision our contributors and friends to whom the matter was first 

 referred have unanimously agreed. It is not proposed to lessen the amount of 

 material devoted to the microscope, but rather to give an additional number of 

 pages each month printed on a finer grade of paper suitable for the illustrations 



required.

Beginning with this number, Mr. Raymond Pearl, Zoological Laboratory, 

 University of Michigan, will conduct a department of General Physiology, which 

 will be devoted to the reviewing of current literature in the field of general 

 physiology, using the term in its broadest sense. No attempt will be made to 

 keep abreast of the enormous literature of medical physiology as ordinarily 

 defined, but we shall rather have to do with that physiology which treats of the 

 life phenomena of all organisms. A special feature will be made of the topics 

 of animal reactions and behavior which are now exciting such general interest. 

 The effort will be made to give practical accounts of all new methods of work 

 along the lines indicated, especially such as can be used by teachers in secondary 

 schools or colleges in demonstrating to classes.
