Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
Excerpt from The American Monthly Microscopical Journal, Vol. 21: For 1900 It is now some five years since I first began to make experiments with a view to finding out how it might be possible, without staining, to cause an object and its background to appear of different colors, and so secure a greater contrast than usual. Up to the present I have found three different ways by which we can make uncolored objects assume any color we wish, and our background any other color. In many circumstances we can also make definite parts of objects themselves assume different colors - if so desired. These effects may be produced so simply that any amateur may make many of the experiments himself at the cost of a few cents. In all microscopes fitted with a condenser in the substage, there is, underneath the condenser lenses, a ring or some form of holder to take stops for dark-ground illumination. Now let us cut out a disc of red gelatine (such as is used for crackers) to fit this ring, then punch a hole in the centre about a third of its diameter, and stick over the hole a piece of blue gelatine of the same size (fig. la). Then we place this color disc in the holder under the condenser, and use it in the same way as we would use the dark-ground stop. We will suppose we are using a 1" objective. The result to those who have not seen it before will be astonishing. The objects, for instance a slide of Polycystina, or some living Rotifers, will appear perfectly red, and the background perfectly blue. The great contrast throws the objects up in a most striking manner. Of course, if we wish to vary our colors, all we have to do is to vary the colors of the gelatine; a yellow disc with a blue centre will show the objects yellow on a blue ground, an uncolored disc with a green centre (fig, 1 b) will show the object white or whatever may be its natural color on a green background, and so forth.

Book Description
Excerpt from The American Monthly Microscopical Journal, Vol. 15: Containing Contributions to Biology, for 1894 The bottles must not be shaked very much when they are taken out of the ice box as the cork might come off and the contents be infected from the air. The cork should be lifted cautiously, and a glass rod dipped down to the bottom of the bottle. When it has been taken out again rapidly, the drop hanging at its end is placed on a slide a cover is put over it, and we have now a sample ready for microscopic examination. Before entering upon the various organisms which might come under observation, it ought to be remem bered that drawings of everything seen should be put down in the note book.
