Text Appearing Before Image:
g solution of silver nitrate (ioo grs. to i oz. of water)may be substituted for the mercurous nitrate, the processbeing the same as already described. It is however onlysuitable to those Diatoms having the finest markings. Whatever method has been employed to mount theDiatoms, the slide should be finished with a ring of asphalt,and when this has become hard a ring of gold size. Theolder the size the better. The cell-making and final ringing will be done with the aidof an ordinary turn-table. Finally label the slide neatly. STUDY OF THE DIATOMACE^. 51 It is a very good plan to add a ring of coloured cement todesignate the mounting medium. The following are thoseused by the author : Dry Black cement. Canada Balsam ... ...White ,, Balsam and Bensole... ..White and red cement.

The student will find that any modern cheap microscopestand made by a good English optician, will answer hispurpose, provided that it be fitted with the means to focus asubstage illuminator. The most efficient of the, cheaper stands is Messrs. R. & J.Becks Bacteriological Star Microscope. This standpossesses fine and coarse adjustments, and a simple substagefitting which can be raised or lowered (in order to focus theAbbe illuminator which it carries), or instantly turned aside.See fig. 1. The student may rely upon any of the followingmakers stands, which- possess a substage :—Mr. C. Baker,Messrs. R. & J. Beck, H. Crouch, Ltd., Powell & Lealand,J. Swift & Son, and W. Watson & Sons.
