17. _Surrey Institution._ At one period (about 1825), this building was
known as the _Blackfriars Rotundo_. Here that execrable character,
Robert Taylor, who styled himself "the Devil's Chaplain," delivered his
blasphemous discourses.

18. _Opera House._ Mr. Cunningham, speaking of the translation of
_Arsinoe_, the first Anglo-Italian opera performed in this country,
says: "The translation was made by Thomas Clayton." This is an error,
for Clayton himself says, in his preface: "I was obliged to have an
Italian opera translated." Clayton was the composer of the music.

19. _James's (St.) Chapel, St. James's Palace._ Mr. Cunningham says,
"The service is chanted by the boys of the Chapel Royal." This ought to
read, "The service is chaunted by the boys _and gentlemen_ of the Chapel
Royal" The musical service of our cathedrals and collegiate
establishments cannot be performed without four kinds of voices, treble,
alto, tenor, and bass.

20. _Bagnigge Wells._ Mr. Cunningham makes a strange mistake concerning
this once popular place of amusement when he says, "first opened to the
public in the year 1767." A stone, still to be seen, let into the wall
over what was formerly the garden entrance, has the following
inscription:

"S + T
This is Bagnigge
Hovse neare
The Pinder a
Wakefeilde
1680."
