Journal of 



Applied Microscopy 



and 



Laboratory Methods 



Edited by L. B. ELLIOTT. 



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. 



We are pleased to be able to announce, beginning with our next issue, a new 

 Department in the Journal, to be called " General Laboratory Methods." This 

 Department will be conducted by Dr. Raymond Pearl, of the University of 

 Michigan, Ann Arbor, Mich., and will consist of notes from current literature, 

 dealing with laboratory technique in a more general way than has been possible 

 in other Departments which are confined more exclusively to microscopical mat- 

 ters. The addition of this Department is in line with the broader policy of the 

 Journal, and will give our readers each month a very considerable amount of 

 material of a kind which we have never before had. We would suggest in this 

 connection that separates of all papers on general zoological subjects, in which 

 there is a method described, be sent to Dr. Pearl for review.

We have recently completed arrangements with Mr. B. J. Howard, U. S. 

 Department of Agriculture, Washington, D. C, whereby we will be able to pre- 

 sent to our readers in the near future, a series of papers on the use of the micro- 

 scope in the detection of food adulterations. The series will be, to a large 

 extent, a compilation of the methods which have been published in foreign lan- 

 guages during the past few years, and will serve when completed as a manual 

 for this line of work. We trust that this will be the first of a series of manuals 

 which we are arranging for, showing the application of the microscope in the 

 industries. The industrial application of the microscope is being rapidly devel- 

 oped, and we shall use every effort to keep our readers posted in the various 

 lines in which its usefulness has been fully demonstrated.

We offer our readers in this issue a most valuable series of papers, recently pre- 

 sented to the Michigan Academy of Science, and published by the Academy for 

 distribution to teachers in the secondary schools in the state of Michigan. Our ob- 

 ject in so doing is to give our readers not only the information which is contained in 

 these papers, but also an insight into the methods which are being employed by 

 our science organizations throughout the country not only to further the interests 

 of science, but to make available to those who need them most the practical 

 results of scientific work and investigation. In addition to the publication of 

 this series of papers, the Michigan Academy of Science has established a nat- 

 ural history bureau for the encouragement of the collection identification and 

 exchange of natural history material throughout the State. Certain members of 

 the Academy, and others interested in its work, have agreed to identify gratui- 

 tously material sent them from the schools.
