Trim, May 13. 1850.
_Dr. Johnson and Dr. Warton_ (Vol. i., p. 481.).--Mr. Markland is
probably right in his conjecture that Johnson had Warton's lines
in his memory; but the original source of the allusion to _Peru_ is
Boileau:
"De tous les animaux
De Paris au _Pérou_, du Japon jusqu'à Rome,
Le plus sot animal, à mon avis, c'est l'homme."
Warton's Poems appeared in March, 1748. Johnson's _Vanity of Human
Wishes_ was published the 9th January, 1749, and was written probably
in December or November preceding.
