PARTS OF THE FLOWER 



Note. — One needs a lens for the examination of the flower. It is 

 best to have the lens mounted on a frame, so that the pupil has both 

 hands free for pulling the flower in pieces. An ordinary 

 pocket lens may be mounted on a wire in a block, as in 

 Fig. 214. A cork is slipped on the top of the wire to avoid 

 injury to the face. The pupil should be provided with two 

 dissecting needles (Fig. 215), made by securing an ordinary 

 needle in a pencil-like stick. Another convenient arrange- 

 ment is shown in Fig. 216. A small tin dish is used for the 

 base. Into this a stiff wire standard is 

 soldered. The dish is filled with solder, 

 to make it heavy and firm. Into a cork 

 slipped on the standard, a crosswire is 

 inserted, holding on the end a jeweler's 

 glass. The lens can be moved up and 

 down and sidewise. This outfit can be 

 for about seventy-five cents. Fig. 217
