" Quod ad me attinet, ingenue fatear, me in rebus dubiis de speciflca differentia 

 nuniquam consulere Auctores, qui in herbariis plantis multis, sed eos modo, qui 

 in natura plantis multum student. At iis, qui ad pneceptas opiniones ei-perien- 

 tiam suam concinnant et in singulo extern* faeiei lusu, neglectis notis t-ssentiali 

 lu, formas transitorias vident, paruin fido." FRits.
