The Microscope and Some Hints on How to Use It #270477

In this little booklet entitled The Microscope and some hints on how to use it we do not in any sense pretend to deal exhaustively, or even in detail, with the working principles ofthe microscope. Lts humble purpose is to furnish a first introduction 'to a more advanced use of the microscope and to offer a guide to those whose work involves an occasional use of the instrument. To the research worker who devotes himself primarily to microscopic observations the booklet presents only so much practical knowledge as will ensure a satis factory measure of success in its use. After a brief review of the optical and mechanical components of the microscope and a short explanation of the process by which the microscope furnishes a magnified image of the object, we shall proceed to elucidate in detail such matters as the aperture of an objective, its resolving power and magnification. Next we shall say a little on the construction of condensers, objectives and eyepieces, and conclude with a few remarks on the measure ments which can be made with the microscope.
