Do not aggravate matters by telling how much I have been annoyed.

Lord Byron has sent me a list of his new poems and some prose, all of which he requests me to prepare for the press for him.

The monied arrangement is to be made by Mr.Kinnaird.When you are ready for me, the materials may be sent to me at this place, where I have taken up my abode for the season.
I remain, very truly yours, JOHN CAM HOBHOUSE.
Towards the end of 1820 Lord Byron wrote a long letter to Mr.Murray on Mr.Bowles's strictures on the "Life and Writings of Pope." It was a subject perhaps unworthy of his pen, but being an ardent admirer of Pope, he thought it his duty to "bowl him [Bowles] down." "I mean to lay about me," said Byron, "like a dragon, till I make manure of Bowles for the top of Parnassus." After some revision, the first and second letters to Bowles were published, and were well received.
The tragedy of "Sardanapalus," the last three acts of which had been written in a fortnight, was despatched to Murray on May 30, 1821, and was within a few weeks followed by "The Two Foscari: an Historical Tragedy"-- which had been composed within a month--and on September 10 by "Cain, a Mystery." The three dramas, "Sardanapalus," "The Two Foscari," and "Cain, a Mystery," were published together in December 1821, and Mr.Murray paid Lord Byron for them the sum of L2,710.
"Cain" was dedicated, by his consent, to Sir Walter Scott, who, in writing to Mr.Murray, described it as "a very grand and tremendous drama." On its first appearance it was reprinted in a cheap form by two booksellers, under the impression that the Court of Chancery would not protect it, and it therefore became necessary to take out an injunction to restrain these piratical publishers.
The case came before Lord Chancellor Eldon on February 9.

Mr.Shadwell, Mr.Spence, and Sergeant Copley were retained by Mr.Murray, and after considerable discussion the injunction was refused, the Lord Chancellor intimating that the publisher must establish his right to the publication at law, and obtain the decision of a jury, on which he would grant the injunction required.

This was done accordingly, and the copyright in "Cain" was thus secured.
On the death of Allegra, his natural daughter, Lord Byron entrusted to Mr.Murray the painful duty of making arrangements for the burial of the remains in Harrow Church.
