PRESERVING PLANT SPECIMENS. 



two or more sheets of the drying-paper. On 

 the top sheet lay the plant, carefully arranging 

 it so that its parts are as nearly as possible in* 

 their natural positions. On the plant place 

 some more sheets of drying paper, and then 

 arrange another plant. (Two plants must 

 never be placed on top of one another between 

 the same two pieces of paper). Go on in this 

 way until all the plants are spread out, and 

 finally put on the second board, and the 

 weights. 



4. By the next day the sheets of paper 

 will probably have become damp, and must be 

 changed for dry ones. Damp papers should 

 be dried in the sun. When changing the 

 plants, lift them carefully and take care that 

 their leaves, etc., are in natural positions. With 

 good absorbent paper, used perfectly dry, two 

 changes are often sufficient, except for thiqk- 

 leaved pLmts, which require more. 



5. For future reference it is advisable to 

 mount the dried plants on sheets of paper. 

 The s.ime size should be used throughout, 

 (10 ins. by 10 ins. is a common and convenient 

 size) and only one species of plant should be 

 placed on any one sheet. Fix the plants to the 

 sheets by small strips of gummed paper.
