Wonderful little piece of Methodist ephemera; Luke Tyerman was of course the most prominent biographer of Wesley during the 19th century. His three volume work was thorough, appropriately critical, and contained a solid bibliographical apparatus. It is still valued today.
The "transaction" Tyerman refers to is the controversy surrounding Wesley's romantic relationship with Grace Murray.
In the present, Tyerman writes to John Holland Esq., as follows:
"Dec. 19, 1870
My Dear Sir,
I am sincerely grateful for your kind communication.
I have long possessed the pamphlet you mention; I have also compared it with the authentic MS in the Museum -
The pamphlet is quite correct, with the exception that it omits two or three not very important paragraphs.
Vol II of my Life and Times of Wesley is already published, and contains, (page 42 to page 57) a lengthened account of the transaction -
Excuse haste, and believe me, very dear Mr. Holland,
John Holland Esq.
