the fructification is already in an 

 advanced ftate; and keep their leaves 

 in the belt condition, and even pufh 

 out continually new ones, long after 

 the whole fructification is fulfilled; 

 which leems to indicate, that the 

 chief ufe of thefe fans is not to 

 aiiift the fructification and propaga- 

 tion of their fpecies. Thefe fans, 

 wtu n compleated, feem to compofe 

 or arrange themfelves in fuch a 

 manner as to expofe their upper and 

 varnifhed fur face to the direct in*, 

 fluence of the fun, and to hide as 

 much as they can their under fur- 

 face from the direct influence of 

 this luminary. It feerris as if they 

 required rather the li^ht of the fun 

 than the influence of its heat, as 

 their polifhed lurfaces muft reflect 

 feme of the rays of the fun, and 



thus moderate the degree of heat.
