His last letter to Mr. Murray refers to the payment for one of these articles: 

Sir W. Scott to John Murray.

ABBOTSFORD, Monday, 1830.

My Dear Sir,

I acknowledge with thanks your remittance of L100, and I will be happy to light on some subject which will suit the Review, which may be interesting and present some novelty.  But I have to look forward to a very busy period betwixt this month and January, which may prevent my contribution being ready before that time.  You may be assured that for many reasons I have every wish to assist the Quarterly, and will be always happy to give any support which is in my power.

I have inclosed for Moore a copy of one of Byron’s letters to me.  I received another of considerable interest, but I do not think it right to give publicity without the permission of a person whose name is repeatedly mentioned.  I hope the token of my good wishes will not come too late.  These letters have been only recovered after a long search through my correspondence, which, as usual with literary folks, is sadly confused.

I beg my kind compliments to Mrs. Murray and the young ladies, and am, yours truly,

WALTER SCOTT.

Scott now began to decline rapidly, and was suffering much from his usual spasmodic attacks; yet he had Turner with him, making drawings for the new edition of his poems.  Referring to his last article in the Quarterly on Pitcairn’s “Criminal Trials,” he bids Lockhart to inform Mr. Murray that “no one knows better your liberal disposition, and he is aware that L50 is more than his paper is worth.”  Scott’s illness increased, and Lockhart rarely left his side.

Mr. Lockhart to John Murray.

CHIEFSWOOD, September 16, 1831.

“Yesterday determined Sir W. Scott’s motions.  He owes to Croker the offer of a passage to Naples in a frigate which sails in about a fortnight.  He will therefore proceed southwards by land next week, halting at Rokeby, and with his son at Notts, by the way.  We shall leave Edinburgh by next Tuesday’s steamer, so as to be in town before him, and ready for his reception.  We are all deeply obliged to Croker on this occasion, for Sir Walter is quite unfit for the fatigues of a long land journey, and the annoyances innumerable of Continental inns; and, above all, he will have a good surgeon at hand, in case of need.  The arrangement has relieved us all of a great burden of annoyances and perplexities and fears.”

Another, and the last of Lockhart’s letters on this subject, may be given: 

Mr. Lockhart to John Murray.

CHIEFSWOOD, September 19, 1831.

DEAR MURRAY,
