I Forgot in my laft to anfwer your Query about Co- 

 rymbiferous Plants. Mr. Bobart told me Dr. 

 Tourneforfs making Bidens a diftinffc Genus, was a 

 falfe Notion > for the Seeds of thofe Plants (as.of ma- 

 ny others of the Corytnbiferx) had each four Spinul<e % 

 though two of them generally fell off before they 

 were ripe. He fays all thofe that have Quadrangular 

 Seeds have four Spinula x which in many Plants fall 

 all off, in others only two remain.

 whence I fuppofe our molt common Gnat comes,
