singing at Sadler's Wells. I have
a copy of the music and the words; altogether identical with those in
the music. Of these, with other matters connected with the {290} amorous
frog, I shall have something more to say hereafter. This notice is to be
considered incidental, rather than as referring expressly to Mr.
Cunningham's valuable book.

P. 153. _Deans Yard, Westminster._--Several of the annual budgets of
abuse, obscenity, and impudent imposture, bearing on their title-pages
various names, but written by "John Gadbury, Student in Physic and
Astrology," were dated from "my house, Brick Court, Dean's Yard,
Westminster;" or this slightly varied, occasionally being, "Brick Court,
_near_ the Dean's Yard," &c. I have not seen a complete series of
Gadbury's _Almanacks_, but those I refer to range from 1688 to 1694
(incomplete). His burial in St. Margaret's, Westminster, in 1704, is
noticed by Mr. Cunningham, at p. 313. As brick was then only used in the
more costly class of domestic buildings, this would seem to indicate
that _prophecy_ was then a lucrative trade; and that the successor and
pupil of the "arch-rogue, William Lilly" was quite as fortunate in his
speculations as his master had been. It is a truth as old as society
itself, that "knaves grow rich while honest men starve." Whilst Gadbury
was "wallowing in plenty," the author of _Hudibras_ was perishing for
want of a crust!

P. 153. _Denzil Street._--Here, about the middle of the street, on the
south side, lived Theophilus Holdred, a jobbing watchmaker, whose name
will always hold a place in one department of mathematical history. He
discovered a method of approximating to the roots of numerical
equations, of considerable ingenuity. He, however, lost in his day and
generation the reputation that was really due to him for it, by his
laying claim to more than he had effected, and seeking to deprive other
and more gifted men of the reputation due to a more perfect solution of
the same problem. He was, indeed, brought before the public as the tool
of a faction; and, as the tools of faction generally are, he was
sacrificed by his own supporters when he was no longer of any use to
them.

I once called upon him, in company with Professor Leyburn, of the Royal
Military College, but I forget whether in 1829 or 1830. We found him at
his bench--a plain, elderly, and heavy-looking personage. He seemed to
have become "shy" of our class, and some time and some address were
