and tough, and used for making Palan queens ; of Wrightia mollissima is employed by 

 turners. Aspidosperma excelsum is, according to Schomburgk, remarkable for its 

 trunk growing at the lower part into tubular projections, forming cavities which serve 

 the Indians as ready-made planks, and in the construction of their paddles. The tinink 

 appears as if fluted, or rather as if it consisted of numerous slender trees grown 

 together along theu' whole length. 



The sages of Ceylon having demonstrated, as they say, that Paradise was in that 

 island, and having therefore found it necessary to point out the forbidden fniit of the 

 garden of Eden, assure us that it was borne on a species of this genus, the Divi Ladner 

 of their country, and probably Tabemsemontana dichotoma. The proof they find of 

 this discovery consists in the beauty of the fruit, said to be tempting, in the fragrance 

 of the flower, and in its still bearing the marks of the teeth of Eve. Till the offence was 

 committed, which brought misery on man, we are assured that the fruit was dehcious ; 

 but from that time forward it became poisonous, as it now remains. — Bot. Reg. 1841.
