BOTANICAL DRYING PAPER 



For Drying Flowering Plants, Ferns, & Seaweeds. 



Preserves form and colour in the best possible manner, and seldom, if ever, 

 requires change of sheets whilst the plants are being dried ; it is stout and durable. 

 Used by the Arctic ships, and on the cruise of H.M.S. ' Challenger.' 



" Combines in a very satisfactory manner the merits of a high degree of absorbence 

 with a reasonable toughness. No doubt, for drying plants, it is the best paper that can 

 be got." — Nature.
