sists in the petals being each furnished on the inside with an ad- 

 ditional scale or a tuft of hairs instead. The only plant in this 

 order which will bear the climate of England is Kcelreuteria pa- 

 niculata, a beautiful tree, with panicles of yellow flowers. Many 

 of the species of Nephelium bear excellent fruit, as well as the 

 Bllghia sapida and Melicocca bijilga. The rind of the fruit of 

 many species of Sapmdus is used instead of soap, in the places 

 of their natural growth.
