Simmons, W. J. — A Metkod of using Bismarck Brown. 



[Carbolic acid, IS minims; distilled water, 1/2 fluid oz. ; dissolve. Add 

 saturated solution of Bismarck brown 3/4 fluid dram ; filter, ami keep in a 

 corked or stoppered pbial. The carbolic acid must be the strongest crystal- 

 lized, and must be diluted in the usual proportion of one part distilled 

 water to twenty parts of the crystallized acid. This method is an adapta- 

 tion of a solution of fnchsin recommended by Gradle, Bismarck brown 

 taking the place of fnchsin. It is well adapted for bacilli and gives 

 excellent results with cells both animal and vegetable. The epithelial 

 cells from the mouth stain in three or four minutes, the nucleus being 

 well brought out. Sections of leaves and stems take a red stain for the 

 nucleus ; the chlorophyll granules at first retain their green colour, pro- 

 ducing a very nice effect with the 1/4 or 1/8 objectives.]

 After an hour or two mount in glycerin jelly. Mount pollen dry, or if 

 too opaque use glycerin jelly. Mount sections of stems in glycerin jelly, 

 first soaking in above solution. As a rule avoid damar or balsam in 

 mounting botanical specimens.]
