to supply information regarding the 

 processes and apparatus employed in converting an object — macroscopic or 

 microscopic — into an illustration. As will be seen at a glance, this field is very 

 wide, including as it does everything from photography of a plant, animal, or 

 rock in the field, to the projection of the finished picture on the screens or its 

 preservation on the printed page. The matter will be selected with great 

 care and only practical methods will be admitted. Fine enamel paper will be 

 used, permitting the printing of abundant illustrations. The Journal for 1900 

 will be larger than heretofore and will contain many useful papers and series of 

 articles, among others, the conclusion of Prof. Chamberlain's papers on methods 

 in botanical microtechnique, Mr. Weiss's exhaustive studies on the bacteriology of 

 the cat's stomach, and Prof. Macbride's paper on methods of studying slime 

 moulds. Prof. Chamot of Cornell University will contribute a series on the 

 equipment of the micro-chemical laboratory and the micro-chemical technique. 

 A series of papers descriptive of the laboratories of the University of Chicago, 

 University of California, Leland Stanford Jr. University, Adelbert College, 

 Hendryx Laboratory at Los Angeles, California State Normal School, and others, 

 will also be one of the features of the year. And many other interesting and 

 valuable papers are already in our hands for publication.

During the past two years we have used extraordinary efforts to introduce 

 the Journal to the notice of every person in America interested in work requir- 

 ing the use of the microscope, and of adding every such person to our subscrip- 

 tion list, knowing that unless a large number of subscribers could be secured the 

 enlargement and improvement of the Journal according to our plans could not 

 be accomplished. Our publishers have been extremely liberal in supplying the 

 necessary copies for this work, which has been done thoroughly. This liberality 

 has, in some instances, been mistaken for an intention to distribute the Journal 

 gratuitously. Such is not the case. There is no free list, and the Journal is 

 dependent for its existence on whether it can be self-supporting or not. It is 

 therefore to be hoped that persons interested will subscribe promptly.

The index for 1809 will be sent out with the January, 1900, number, and 

 will consist of a general index, an author's index, and a list of papers noticed in 

 the review department. Our subscribers would do well to bind their volumes, 

 as only a few sets of our stock of back numbers remain, and the volume for 

 1899 will soon be out of print.
