Such gatherings may be put up as obtained, or have alcohol added to them for better preservation. The collection of aquatic plants from the mouths of rivers is extremely desirable, --such as have been made in the delta of the Ganges yielding interesting results. The refuse of dredging for shells often yields mud, old shells, or algse; and collectors will do well to secure such. Experience, however, will teach the best places to look for recent diatoms; but the above general directions will prove of service to those who are new to the pursuit, or who collect for others. It should always be remembered that a knowledge of the exact locality is of the greatest importance, --so that upon the label should be written in ink the locality, date of collection, and name of collector. Other facts deemed of interest may also be added. HOW TO PREPARE SPECIMENS OF DIATOMACEJZ FOR EXAMINATION AND STUDY BY MEANS OF THE MICROSCOPE. Having accumulated a number of gatherings of rough material, which, a cursory examination has shown, contain specimens of diatomacese, and which, it is judged, it will answer to clean and otherwise arrange and put up, or as it is technically termed, "mount," for future study, the intending diatomist requires to be informed how he may best set about preparing his specimens in the most advantageous manner. The author of the present sketch has published, in the seventh volume of the Proceedings of the Boston (Mass.) Society of Natural History, certain directions for collecting, preparing and mounting diatomacese for the microscope; and as that paper contains a large part of the information he desires to impart at the present time, ...
