58 SCIOPTICON MANUAL. 



LONG SLIDES. 



A very largo class of paintings, on strips of glass 12 

 or 14 inches long, have come down to us from a former 

 generation. Many of them hardly deserve attention, 

 but some Nursery Tales, Natural History, &c., are fair, 

 and the Astronomical set, in particular, is excellent. 



Fig. 22. 



This set of ten astronomical slides, with forty-one 

 illustrations, together with a set of astronomical dia- 

 grams with rack-work motion, makes a very complete 

 outfit for a series of astronomical lectures. 



DIORAMIC PAINTINGS WITH MOVING FIGURES. 



In the middle of a glass strip (shaped and framed tn in 

 Fig. 22), a scene is painted, the rest being made opaque. 

 Another glass strip, of similar size and shape, on which 

 is painted along its whole length whatever is befitting, 

 as figures, boats, &c., is made to pass in front in grooves, 

 so as to represent a long procession; of this class, the 

 children of Israel passing through the Red Sea is an ex- 

 ample ; or, the enterprising smugglers secreting contra- 

 band goods in the smugglers' cave. 



THE GHOST. 



A description of the modern "ghost" may be looked 

 for here,, but it is not strictly a magic lantern production.
