I am favoured with your obliging letter, and shall finish your picture in two or three days at farthest, and send to Colchester according to your order, with a frame. I thank you. Sir, for your kind intention of procuring me a few heads to paint when I come over, which I purpose doing as soon as some of those are finished which I have [now] in hand. I should be glad if you'd place your picture as far from the light as possible; observing to let the light fall from the left.
