Book excerpt: Excerpt from The Microscope and Its Relation to Medicine and Pharmacy, Vol. 2: April, 1882 Many of those require neither preparation nor mounting, being too common or abundant to repay the slightest labor bestowed upon them. Others, however - and their same is legion - can and should be preserved in some permanent manner, readily accessible, and easily arranged for examination. In the vegetable kingdom we are presented with an endless and charming variety of beautiful forms in the seeds of even our commonest flowers, or even weeds, whilst the feathers, scales and hairs of the animal afford a never ending storehouse of treasures for the seeker after the curious and beautiful. The pollen from the tinniest flower, or the sands from the shores of the mighty ocean, alike present us forms and colors of surpassing beauty; and the preservation of these in a permanent form is at times most desirable. It shall be the purport of the present paper to point out some plain methods of doing so, which will produce good results if carefully followed. Let us term this method of mounting "The Dry Way," to distinguish it from those preparations made in aqueous or other fluids, and proceed to make our mount in one of the several ways whereby it may be done. The books have been filled with such for years, good, bad, and indifferent. We have had full discussions of the merits and demerits of cells, possible and impossible; some made of shellac, turned upon a whirling table with the point of a pen-knife, at an immense expenditure of time and patience; others of wax, bone, tin, hard and soft rubber, curtain rings, and a host of other substances; anything, in fact, but those, or rather that possessing the one quality needful for a dry cell, namely, the quality of remaining dry. For be it distinctly understood, that though a cell may be made and hermetically sealed, in which no appearance of moisture will ever occur, such an event is an anomaly and can never be duplicated with any certainty. No matter how dry the specimen may appear to be, nor the atmosphere of the room or the surface of the covering glass, sooner or later the under side of latter will become covered by a mist like substance, which obscures and spoils the view of the imprisoned specimen. This of course is the case only with such preparations, as are mounted on the bottom of a cell of any depth, the cover being used merely as a protection from dust and other injury.
