Autograph letter signed : Brussels, to Robert Wallis, [1836] "Monday".

Sending drawings for his next book, The history and topography of Holland and Belgium (London : George Virtue, 1837); asking how matters stand between the recipient and his publisher George Virtue, as he is anxious that his drawings be "put as before into your hands"; expressing how much he misses the recipient's society and advice; gives a description of the city of Brussels in winter ("winter is the time to see the old Flemish cities - a moonlight night here is quite a treat from the magnificent effects upon the gothic buildings"); asks for candid criticism and advice upon the enclosed drawings and requests that they be sent to Kentish Town (where Bartlett had his permanent residence) "after you revised them", to be mounted and sent on to Virtue; provides comments and instructions regarding his illustrations for William Beattie's Switzerland (London : George Virtue, 1836), then in the course of serial publication, including a suggestion that one of his cancelled drawings serve as a vignette, with a small landscape sketch of a view of Meiringen in the text of the letter illustrating the sort of design he would recommend.
