ENTOMOLOGICAL 



MICROSCOPE 



The stand of this microscope packs in a conve- 

 nient manner into a handy flat case, wliich also 

 serves as a foot for the stand. The latter is fitted 

 with rack and pinion only, which is quite sufficient 

 for the low powers with wliich the entomologist is 

 concerned. The usual stage is in this 

 instrument replaced by a detachable 

 saddle bracket, one arm of which car- 

 ries a ball-jointed cork piece for the 

 attachment of insects, whilst the 

 other carries on a vertical rod & ball- 

 jointed arm a universally movable 

 bull's-eye lens.
