 quired. It is tough, strong, and not too bibulous. The sheets 

 ought to be cut all of one size by being laid on each other, 

 not after being folded one within another, and then cut ; by 

 the latter method of cutting the sheets vary in size. 



In addition to this drying paper a few sheets of very thin 

 but tough packing paper should be taken, in which fragile 

 specimens can be laid out and dried without removal. 



The paper should be cut to 19 J inches by 11 inches, and 

 each sheet laid on the top of the other, not packed up in 

 bundles of so many sheets, one within another.. 



Locality tickets, 4 inches by 3 inches, of coarse paper, with 

 a rough surface on which to write with pencil. Four tickets, 

 at the very least, should be allowed for each sheet of paper. 



There should be ten good strong pieces of millboard, each 

 cut to 2,0 inches by 11| inches; these should be placed through 

 the drying paper, so as to divide it up into so many equal 

 parcels.
