Excerpt from Practical Methods in Microscopy There are many excellent books on the microscope, and many on special subjects requiring the use of the microscope as a working tool for investigation. In the most of these books, however, the descriptions of methods are so inter woven with other matters that the inexperienced student is confused and, in many cases, is unable to separate the essential from the non-essential. Too much is assumed to be known, or is left to be filled in by an instructor. None of these books gives to the private worker, in simple and concise language, detailed directions for the many processes that he must learn in order to make practical use of the microscope. A large amount of apparently unproductive work must be done before the microscope can be advantageously used as a working tool. It is of the highest importance that this work be done at as early a stage as possible, and without waste of time. This book is professedly for beginners and private workers, and is designed to afford the means of acquiring this necessary training. The methods here described are practical methods which have stood the test of general use. They are the methods employed by scientific men the world over. It would not be possible, in most cases, to give credit to the originators of the processes, as the processes have been the result of slow growth, and have been so modified by different workers that they have become common property. Credit can, therefore, be given only in this general way to the books and workers that have furnished the material which has been drawn upon.
