The manuscript letter dated 20 December 1878, signed 'J H Burton' to 'My Dear Morton', probably the Edinburgh solicitor Charles Morton. Burton regretfully declines an invitation as 'prudence forbids. I have not dined out in Edinburgh for 10 years fidning it dangerous [...] I felt always the worse when I dined with Russel or any other good fellow, so took a self denying ordnance'. He is sending 'a little book', preferring it to his others because 'it is personal to the author. Farther it may have to you the value of being commemorative of well remembered ground [...] Now don't take the trouble of acknowledging receipt [...] I speak as one wjo has been a considerable sufferer from receiving authors presentation copies'.
There is also a ms transcript of the letter.
