Dr. Pefchier of Geneva thinks, he has difcountenanced this idea of 

 amatorial fenfibllity of vegetables by two experiments, which are re- 

 lated in Journal de Phyfique de Lametherie, T. II. p. 343. One of 

 thefe confiiled of his tying down the ftigma of epilobium anguftifo- 

 lium, and yet in due time the anthers buril and (hed their pollen, and 

 thus committed a kind of vegetable Onanifm ; and alfo that he caf- 

 trated the ftamens of this flower, and yet the ftigma opened and arofe, 

 as if the anthers had been prefent. The other experiment confifted 

 in his confining a branch of barbery, berberis, in a glafs, and fubjed- 

 ing the flamina of the flowers to the vapour of nitrous acid, which 

 by this flimulus arofe from their petals to the fligma, and after a few 

 minutes again retired to their petals. Both thefe experiments rather 

 feem to confirm than to enfeeble the analogy between plants and
