are carried successively through two baths of xylol and mounted in 

 balsam. The tissue elements are stained in the methyl-green aniline 

 oil, but the intensity of the stain cannot be determined until after the 

 sections have passed through the essential oil and xylol. If the tissues 

 are then found to be too feebly stained, they may be transferred back 

 to the methvl-green aniline oil for some minutes until the desired in- 

 tensity is obtained. 



Bv this method the tissue elements are clearly diflerentiated from the 

 sharply and delicately stained bacilli. If an after stain of methylene- 

 blue is desired the sections may be transferred from the alcohol to a 

 weak solution of alkaline methylene-blue. After staining in this for 

 from five to ten minutes they are rinsed in weak, dehydrated in strong 

 alcohol, cleared, and mounted in the usual way.

 manner as the methylene-blue aniline oil by substituting the methyl-

EDITORIAL. 



The Microscope. — Our esteemed contemporary, which, being 

 nearly as old as this periodical, is doubtless known to all our readers, 

 after being ably conducted for a number of years by Dr. Manton and 

 others, of Detroit, has migrated to the East in search of wise men. It 

 was not necessary to find but one to take charge of its columns, when 

 such a man as Dr. Alfred C. Stokes is at hand. He, too, needs 

 no introduction to any microscopist in the United States or Europe. 

 Many times he has favored us with his contributions, and if he does not 

 continue to do so we may, perhaps, extract some of his writings from 

 his new journal. The Doctor's '• Microscopy for Beginners," which 

 was published two years ago, has had a large sale and is on our shelves 

 for constant reference. The transactions of the Trenton Natm^al His- 

 tory Society have been greatly enriched by the Doctor's contributions. 

 He has an easy flow of language, is not disposed to conceal his knowl- 

 edge from common people, and has a large sympathy for amateurs. 

 We welcome him most heartily and sincerely to the editorial ranks, and 

 bespeak for him that kindness which the microscopical readers have 

 always shown to ourselves.

Two Energetic Microscopists. — There are two men who are 

 prominent in our branch of science whose career we watch with much 

 interest. Their names are Dr. W. J. Lewis, of Hartford, Conn., and 

 Dr. Frank L. James, of St. Louis, Mo. The former has been presi- 

 dent of the American Society, and the latter deserves to be made presi- 

 dent next year. It is rare that so young men attain such prominence, 

 and it argues in this instance many years of contribution to this science, 

 if their lives are spared, as we hope will be the case. 



Perhaps the above is a sufficient apology for the remarkable error we 

 made in the October number, page 236 (14th line from bottom), where 

 some able remarks are credited to the former, whereas they should have 

 been reported as by the latter, viz : by Dr. James. Will our readers 

 please note the correction ?
