Under the younger Havell's guiding hand, Audubon found that his illustrations could be produced in better style, more expeditiously, and at far less cost than in Edinburgh. When Lizars was later shown the third number which the Havells had produced, he called his assistants and observed how completely the London workmen had beaten them; he even offered to resume work on the engraving and at Havell's price, but Audubon was averse to further experimenting. "If he can fall," said he, "twenty-seven pounds in the engraving of each number, and do them in a superior style to his previous work, how enormous must his profits have been; a good lesson to me in the time to come, though I must remember Havell is more reasonable owing to what has passed between us in our business arrangements, and the fact that he owes so much to me." This characteristic note was sent from Liverpool, December 6, 1827, to his agent, Daniel Lizars, father to W. H. Lizars, at Edinburgh: I will not ask if you have any new name for me, as I _might_ be disappointed were I to expect an affirmative answer. If you see Sir Wm. Jardine tell him that Charles Bonaparte has left the U. S. for ever, and has gone to reside in Florence, Italy. I have wrote to Mr. Havell to send you a No. 5, which I wish you to send to Professor Wilson, or indeed a whole set, to enable him to write the notice he has promised for me the 1st. of next month.

I am extremely anxious to close my business for 1827, and cannot do so without receiving your a/c, and the money due by my subscribers."
