botanica

His 'Bibliotheca Botanica,' two quarto volumes, appeared at Zurich in 1771-72.

Robert also cultivated botany, and, when an oldish man, he published his 'Principia Botanica.'

While there he issued his Fundamenta Botanica, an unassuming small octavo, which exercised immense influence.

During the compilation he used to “amuse” himself with drawing up the Critica Botanica, also printed in the Netherlands.

Fundamenta Botanica, quæ majorum operum prodromi instar, theoriam scientiæ botanicæ per breves aphorismos tradunt.
