solved in one quart of water and a few drops of 

 vinegar. Leave them in until they look quite 

 white, and then wash in several waters to get the 

 lime out. Dry in blotting-paper under a little 

 pressure. 



Willow, maple, chestnut, elm, and rose leaves 

 skeletonize more successfully than others. Septem- 

 ber is probably the best month for this operation, 

 as the framework attains its greatest strength by 

 that time. 



NOTES UPON LEAF-ANALYSIS. 



i. It is not necessary to know the name of a 

 leaf in order to analyze it. If the name is found 

 out afterward, it can be added to the analysis.- 



2. When the leaves of a plant differ very 

 much from one another, two or three may be 

 analyzed ; but they should be given the same num- 

 ber. 



3. On the blank page opposite each schedule 

 should be placed a printing, drawing, painting, or a 

 pressed specimen of the leaf analyzed.
