E72  Variae observationes circa series infinitas
(Various observations about infinite series)
Summary:
This is the paper in which Euler product expansions first appeared.
In the Enestrom Index, it is recorded that E72 was presented to the St. Petersburg
Academy on April 25, 1727. (This is probably a typo, and should read 1737.)
