more » ... Disk Revolver" of Messrs. Smith, Beck, and Beck is a very convenient instrument for examining small opaque objects at any angle. The "Morris Rotating Object-Holder", supplied by Mr. Crouch, answers the same purpose, and is much cheaper. Opaque injections are exceedingly well shewn by means of it, inasmuch as, while still remaining in the field of vision, they can be inclined at any angle, and their various parts thus successively brought into view. i Postscript.--Mr. Steward, 406, Strand, and 54, Cornhill, has a Student's Microscope at moderate price. It has coarse rack and pinion adjustment, fine adjustment, mechanical stage, mirror with sliding arm, diaphragms, etc. French object-glasses (combinations) are supplied with this instrument, but may be exchanged without additional cost for English glasses (one inch and quarter-inch) of Mr. Steward's own make.
