Charles William Sutton, Dictionary of National Biography… (1889)
“ An epidemic fever in the town was the means of drawing public notice to the wretched condition of the dwellings of the working classes, and led Ferriar to take an active and important part in causing the local authorities to pay more attention to sanitary laws. He urged especially the establishment of baths, the shortening of the protracted hours of labour of the factory children, and the closing or cleansing of insanitary dwellings. He was a principal worker in connection with the Manchester board of health, and with the establishment of fever-wards at Stockport. ”
