L'Hospital on Leibniz
"I must here in justice own, (as
Mr. Leibnitz (sic) himself
has done in Journal des Scavans
for August, 1694) that the learned Sir Isaac Newton likewise discovered
something like the Calculus
appears by his excellent Principia,
published first in the year 1687 which almost wholly depends upon the
use of the said Calculus.
But the method of Mr. Leibnitz's
is much more easy and expeditious, on account of the notation he uses,
not to mention the wonderful assistance it affords on many occasions."
