Doctor Monro was a patron of artists such as Girtin and Turner. His own work was influenced by Gainsborough. His drawings are interesting because he worked with solid sticks of Indian ink, which he used like chalk, drawing onto dry or dampened paper depending on the type of line he wanted. Used on dry paper the stick would produce fine, hard outlines; on wet paper it would produce soft velvety lines. Occasionally Monro wetted the stick before applying it. He would combine this with dilute black ink washes, occasionally scratching into the paper to suggest light.
