The texture of Dalton Collecting marsh Fire Gas can be said to be smooth and polished. The atmosphere of the Dalton Collecting Marsh Fire Gas is calm, thought-provoking and full of life as the different figures in the paint are engaged in different activities.

Madox Brown was profoundly inspired by Lord Byron's poem, Manfred, and this led to his work The Jungfar in 1841 while he was in Paris. Through the brotherhood, Pre Raphaelite Brotherhood, he formed with other artists, he adopted bright colors and realistic style of painting from William Holman Hunt and John Everett Millais. He was also influenced by the work of Holbein that he saw in Basel in 1845, and by Friedrich Overbeck and Peter Cornelius whom he met in Rome from 1845 to 1846.

His painting The Last of England was inspired by Pre raphaelite sculptor Thomas Woolner. He inspired Gabriel Rossetti who became his tutor and also a lifelong friend and admirer of his work. Other works by Madox Brown include The Reverend in 1837, Execution of Mary, Queen of Scots in 1839, Dr primrose and his Daughters in 1840, Manfred on the Jungfrau between 1840 and 1861 and Out of Town among many others.
