'Unfortunately I met Mr. Turner at the Academy a night or two after I received this letter ; and he asked me if I had heard from Mr. Lennox. I was obliged to say 'yes.'The picture filled me with awe and the quote made me laugh. Turner, you have it all!
'Well, and how does he like the picture?'
'He thinks it indistinct.'
'You should tell him,' he replied, 'that indistinctness is my forte.'
