HOW To Print Your Palm.— Burn a piece of gum camphor, 

 accumulate the smoke on a piece of smooth, white, paper. Put the 

 smoked paper flat on the table and hold your palm down firmly on it. 

 Remove it carefully. Wet the clean side of the paper with turpen- 

 tine and let it dry well. This holds the smoke on the paper and shows 

 the print of all your lines if well done.
