In the " Natural Hiftory of Cornwall*^ 
by William Borlace, A.M. F.R.S. Ox- 
ford, 1758, we meet with a very brief lift, 
containing about thirty-eight land plants, 
and twenty fuciy with fome fcattered remarks 
on the qualities and ufes. Among the rare 
plants are the Verticillate Knotgrafs, the 
Roman Nettle, the Gunhilly Heath, and the 
Corni/h Pennywort; of which laft there is 
a very indifferent figure in tab, 29. f. 6. 
Under the article Sun-dew, ( Drofera J there 
is a curious and interefting obfervation made 
by Dr. Borlace, in which he afferts, that 
the well-known pernicious quality of that 
vegetable, in producing the rot among ftieep, 
where it abounds, does not arife from any 
cauftic power in the vegetable, but from an 
infett, which lays its eggs, and feeds on the 
A a 2 , plant.
