ping obstinate quartan fevers, than internal 

 astringents, and the so much celebrated Pe- 

 ruvian bark.* 



Rue thrives best in a brick earth, but will 

 not endure dung. It should be planted in 

 situations that are open to the sun. 



It is worthy the attention of the curious 

 to observe the blossom of this plant : the 

 manner in which it is fecundated is a pheno- 

 menon not exceeded by any flower. By the 

 class of the plant it will be observed, that 

 the flower contains but one pistill, which is 

 large in proportion to the petals, as are the 

 ten stamina, the filaments of which are long : 

 when the pollen or farina is matured, two or 

 three of the filaments bend over, forming a 

 quarter of a circle, and discharge their im- 

 pregnating powder on the stigma, and then 

 return to their straight position, and the 

 next two or three take the same direction, 

 until the whole have performed their office 

 with the exactest regularity. 



The wild rue is of so powerful a nature, 

 that it often sends out vapours that will 

 even scorch the face of those that look close 

 on it.
