My dear Miss Jones -
You will very greatly oblige me if you can come here and sit again for a few days - I am to go out of town next week and the picture is wanted at once - Pray come tomorrow morning under any circumstances, so that even should you be engaged we might make some arrangement -
J A Whistler
Wednesday. Jany. 17.
1. 17 January 
According to an almanack, 17 January was a Wednesday in 1866.
2. Millie Jones
Emelie ('Milly') Eyre Jones (b. ca 1851), model, later wife of F. H. Robson [more]. She was one of the models for Symphony in White, No. 3 (YMSM 61) and possibly for Whistler in his Studio (YMSM 63).
3. out of town
JW was about to leave for Valparaiso, Chile.
JW was probably asking Millie Jones to pose for Symphony in White, No. 3 (YMSM 61). According to his mother, as early as November 1865 JW was putting what were intended as the finishing touches to the painting, and hoped to sell it to Louis Huth (1821-1905), collector [more] (see her letter to JW, 25 November 1865, #06526). It was signed and dated '1865' at that time. However, JW continued to rework it until it was exhibited at the Royal Academy in 1867, with '1865' changed to '1867'.
