This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1896 edition. Excerpt: ...a sharp razor, over the edge of which it rapidly sweeps to and fro. Each time, a minute slice of the block is cut off, and, with each thin slice of paraffin, a thin slice or section also of the imbedded fish is removed, and the series forms a continuous ribbon. When the little fish has been thus cut into microscopic slices, all that remains to be done is to arrange them on a slide, to remove the paraffin, and to mount them permanently in Canada balsam or some other microscopist's medium. The final result we are shown in, the shape of an oblong glass slide, such as we were looking at a few moments ago, upon which rows of minute dots are seen. These dots are the thin slices of the little fish, and they are protected by a fine glass cover, duly fixed. Such a slide, placed under the microscope, and carefully examined, will reveal the structure and internal arrangement of a young fish from the tip of the snout to the end of the tail. Some of these slides are several inches long, and may contain from 50 to 500 or more thin slices. Hundreds of such slides are prepared in the Laboratory, and these must be studied before any account of the development of a growing fish or other organism can be written. Time hastens on, and we cannot trespass longer on the kindness of the attendant, or he would show us many more instruments and processes no less remarkable and novel. That large chest, with glass doors and numerous drawers, contains many thousands of microscopic preparations, including fishes' eggs, larval fishes, and hosts of other interesting objects. Before leaving the Laboratory let us look out of one of the windows facing the bay. What a scene of beauty bursts upon our eyes--it is enough to make us envy the diligent workers, who, day by day, have this...
