to his Sxlloge ftirptum exterarum , Dr. Grew carried 
farther, as we find by his works j and it was followed 
by [) Rodolphus Jacobus Camerarius, profefTor at 
Tubingen : but our very indnftrious and fagacions 
member Mr. Morland * * purfued long after this in- 
quiry ftill much higher, as we fee by his excellent 
memoir publifhed in the Pkilofophical Tranfaflions, 
to which i muft beg leave to refer you. After thefe, 
Meflieurs Vaillant and Geoffroy illuftrated and 
{Lengthened thefe difcoveries by very curious and 
well- adapted experiments ; fo that at prefent nothing 
feems wanting for the confirmation of the truth of 
this dcdxine. 
So much for the difcovery of the fex of plants in 
general, upon which profefTor Linnaeus of Upfal has 
founded his fyflem of botany, at prefent fo much 
and fo well received. Whoever therefore would con- 
fider minutely the ftrudture of flowers and the almofl 
infinite variety of the number and difpofition of their 
parts, may confult Linnaeus’s Philojophia botanica 
lately publifhed, where this fubjedt is treated in a 
■ very copious and inftrudtive manner.
