, a canon of Zurich, and professor of
natural philosophy and mathematics in that university,
probably belonging to the same family as Conrad, was born
in 1709. He studied at Leyden and Basle with Haller,
and maintained a close correspondence with him during
the life of that distinguished man. Their taste for botany
was the same, and their characters similar. His letters
make an interesting part of the “Epistolae ad Hallerum,
”
and abound with solid and curious botanical criticism and
information. He paid much attention to the cryptogamic
class, and other difficult branches of the science, as well
as to the anatomy and physiology of plants. He survived
his learned friend twelve years, dying in 1790, at the age
of eighty-one.
