188 SCIOPTICON MANUAL. 



ATTACHMENTS FOR USE WITH THE LIME LIGHT. 



THE LANTERN MICROSCOPE. This instrument is in- 

 tended to show natural objects, suitably prepared and 

 mounted with Canada balsam, between two discs of glass. 

 They consist of details in the anatomy of a bee, wasp, 

 flea, spider, larvae of insects found in stagnant water, as 



gnats, dragon-flies, parasitic and other insects; parts 

 of insects, sections of woods, teeth, bones, fossil bones, 

 shells, lace, silk, muslin, etc. ; and as such objects are 

 smaller than paintings for the lantern, and contain more 

 delicate details,, a proportionately higher magnifying 

 power is required, which may be adapted to the front 

 of the Sciopticon. 



The ordinary lantern microscope objective, sold at 

 about $10.00, has a high and low-power combination. 

 There is, however, all the need of achromatic objectives 

 for projections that there is for the common microscope ; 

 in which case the cost cannot be less. The apparatus 

 shown at Fig. 52, with an inch objective, costs about 

 $60.00. The objectives of a table microscope might 

 doubtless be adapted to lantern use. Of course there can 

 be no satisfactory results without proper adaptations, 

 and perfect alignment and adjustment of distances.
