    ELEMENTARY MICROSCOPICAL MANIPULATION. Microscopical observation lues received a powerful im- petus within the lust few years by the introduction of really good, cheap, and powerful instruments. As optical science has improved and competition between makers has been keener, so the microscopes of the present day have in their essential points been made so excellent as to leave little to add or desire. It is now within the power of any one able to command a few pounds sterling, and having the desire to investigate the marvellous microcosm lying around, to procure such an instrument at a moderate cost, as will give correct detining powers, a good field of view, and a magnification of from 30 to 300 diameters, with all the necessary stability in the microscope stand which con- stitutes comfort in working. An interest has awakened amongst all classes of late years in the minute structures of animal and vegetable life. The subject has been brought under the notice of the public by lecturers, as well as by frequent reference to it in the columns of the press, and probably many might take up this most interesting study were the imaginary obstacles removed from the path of its approach. It is the raison d'etre of this little Manual to deal with these diffi- culties in the most explicit manner, and thus lead the possessor of his first microscope into the smooth path of progress, by pointing out the simplest and most elementary methods of observation, and after so far clearing the way leading him gradually to the higher branches of Microsco- pical Manipulation. n
