The Rev. Dr. Wellesley, Principal of New Inn Hall, has kindly placed
at my disposal his copy of Boswell's "Life of Johnson" (edition of
1816), plentifully sprinkled with marginal notes by Mrs. Piozzi.

The Rev. Samuel Lysons, of Hempsted Court, Gloucester, has liberally
allowed me the free use of his valuable collection of books and
manuscripts, including numerous letters from Mrs. Piozzi to his
father and uncle, the Rev. Daniel Lysons and Mr. Samuel Lysons.

From 1776 to 1809 Mrs. Piozzi kept a copious diary and note-book,
called "Thraliana." Johnson thus alludes to it in a letter of
September 6th, 1777: "As you have little to do, I suppose you are
pretty diligent at the 'Thraliana;' and a very curious collection
posterity will find it. Do not remit the practice of writing down
occurrences as they arise, of whatever kind, and be very punctual in
annexing the dates. Chronology, you know, is the eye of history. Do
not omit painful casualties or unpleasing passages; they make the
variegation of existence; and there are many passages of which I will
not promise, with Æneas, _et hæc olim meminisse juvabit_."
"Thraliana," which at one time she thought of burning, is now in the
possession of Mr. Salusbury, who deems it of too private and delicate
a character to be submitted to strangers, but has kindly supplied me
with some curious passages and much valuable information extracted
from it.

I shall have many minor obligations to acknowledge as I proceed.

Unless Mrs. Piozzi's character and social position are freshly
remembered, her reminiscences and literary remains will lose much of
their interest and utility. It has therefore been thought advisable
