 ^'^Lithography. — An experiment has lately been made to 

 take off impressions from the leaves of plants, by lythogra- 

 phic printing. It appears to have been attempted by mere- 

 ly pressing the leaves against the stone. This process does 

 not, however, appear the most adviseable ; the better way 

 being to cover the plant with the prepared ink, and after 

 bringing a sheet of clean paper in contact with its entire 

 surface, transfer the impression thus procured to the litho- 

 graphic stone. We notice this from the great advantage 

 which botanists are likely to derive from this simple mode 

 of preserving and multiplying impressions from rare plants, 

 which could otherwise, be seen only in the cabinets of a 

 few collectors."
