then with your brush lay on it very equably a good coat of the prepared varnish; let this dry for an hour, more or less, according to the dryness of the atmosphere and the thickness of the coat of varnish.  Meantime cut and trim your designs carefully to fit the glass, (if it is one entire transparent sheet you will find it little trouble;) then lay them on a piece of paper, face downwards, and damp the back of them with a sponge, applied several times, to equalise the moisture.  After this operation, arrange your time so that your designs may now be finally left to dry for fifteen minutes before application to the glass, the varnish on which has now become tacky or sticky, and in a proper state to receive them.  Apply the printed side next to the glass without pressure; endeavour to let your sheet fall perfectly level and smooth on your glass so that you may avoid leaving creases, which would be fatal.  Take now your palette, lay it flat on the design, and press out all the air bubbles, commencing in the centre, and working them out from the sides; an ivory stick will be found useful in removing creases; you now leave this to dry, and after twenty-four hours apply a slight coat of the liqueur diaphane, leaving it another day, when if dry, apply a second coat of the same kind, which must be left several days:  finally, apply a coat of varnish over all.  If these directions are carefully followed, your glass will never be affected by time or by any variations in the weather:  it will defy hail, rain, frost and dust, and can be washed the same as any ordinary stained glass, to which, in some respects, it is even superior.  It is impossible to enumerate the variety of articles to the manufacture of which diaphanie may be successfully applied as it is not confined to glass, but can be done on silk, parchment, paper, linen, &c., after they have been made transparent, which may be accomplished in the following manner:—­ stretch your paper, or whatever it may be, on a frame or drawing board, then apply two successive coats (a day between each,) of diaphanous liquor, and after leaving it to dry for several days, cover it with a thin layer of very clear size, and when dry it will be in a fit state to receive the coat of varnish and the designs.  Silk, linen, or other stuffs, should be more carefully stretched, and receive a thicker coat of size than paper or parchment; the latter may be strained on a drawing or any other smooth board, by damping the sheet, and after pasting the edges, stretching it down while damp.  Silk, linen, or other stuffs require to be carefully stretched on a knitting or other suitable frame.  Take great care to allow, whatever you use, time to dry before applying the liqueur diaphane.  All kinds of screens, lamp-shades, and glasses, lanterns, &c., &c., may be made in this way, as heat will produce no effect upon them.  The transparent pictures are successful, because they may be hung on a window frame or removed at will, and the window blinds are
