The present number closes the fifth consecutive year of publication of the 

 Journal of Applied Microscopy and Laboratory Methods. Since its begin- 

 ning, our single purpose has been to make it a journal of work for workers by 

 workers, and its function has not only been the publication of original work within 

 the field of methods and apparatus, but also the publication of compilations of 

 methods on specific subjects, making them readibly accessible. The result has 

 been, in the five volumes already issued, a very large mass of work, methods, 

 and formulae, brought together in convenient form for daily reference, and the 

 fact that very large numbers of complete sets have, within the past two years, 

 been ordered by libraries and laboratories, encourages us in our policy of broaden- 

 ing the scope of the Journal still more, as we have progressively done each 

 year, until, when we have succeeded in obtaining the support of workers in biolog- 

 ical sciences very generally, we hope to make the Journal a hand-book of labo- 

 ratory work, not only confined to the microscope, but including field methods 

 employed by the student of animals and plants ; the how and why of the teaching 

 museum and practical reference work for the laboratory lanternist, in fact, to 

 cover that ground relating to methods and apparatus of a biological character 

 which is not covered by any other publication in this country. 



The opposition which we encountered at the beginning of our publication, 

 through the belief of many that the Journal was not an independent publication, 

 and that its reading pages would be hampered through relation with its publishers, 

 has entirely disappeared, and our five years of steadfast adherence to our orig- 

 inal purpose of publishing a purely scientific and useful work has gradually 

 brought us the approval of so many of our leading workers, that we feel encour- 

 aged to ask, during the coming year, a still more general publication of papers 

 within our field in the Journal, in order that it may become what we have 

 hoped it would, a truly representative American publication. 



We have arranged for several very important series of articles for the coming 

 year, and many very interesting and useful papers. The Journal will be pub- 

 lished hereafter entirely on fine coated book stock and no effort will be spared 

 to use as many illustrations as can profitably be employed to illustrate the text.
