CITATIONS 339 



ber. Clayton was for some fifty years Clerk of the 

 Court of Gloucester county. Dr. Clayton died in 1773. 

 " He left behind him two volumes of manuscript, pre- 

 pared for the press, and a hortus siccus of folio size 

 with marginal notes and directions for the engraver. 

 As a practical botanist, Clayton was perhaps inferior 

 to no botanist of his time. His descriptions of plants 

 are in general so correct that it is scarcely possible to 

 remain in doubt concerning the precise species which 

 he described. This is especially the case in the latter 

 numbers which he transmitted to Gronovius." Jonathan 

 Stokes, M. D., in Rees's Encyclopaedia. Clayton's 

 manuscripts were burned in the fire which destroyed 

 the Court House of New Kent county during the 

 Revolution. The records have become so dim that he 

 is not mentioned in Johnston's Old Virginia Clerks.]
