Before turning to the forearm in March of 1850, Lister examined the inside of the chest. This is the darkest and most dense of his drawings, also the most aestheticized, pattered by the repetition of the ribs inside the chest.

The perspective taken is from beside the horizontally lain dissected caver. The foreshortening of the set of ribs furthest from the artist’s point of view is unconvincing, as the ribs do not appear parallel and Lister seems uncertain as to whether to render them schematically or realistically.
