This printed paper label is from a packet of 'Chloride of Lime'. Headed 'Chloride of Lime', the label explains that the 'preparation destroys all offensive and putrid efflucia, retards putrefaction; it purifies the air in sick or close rooms, and situations exposed to noxious vapours'. It also includes directions for use. At a time when many believed cholera was spread through foul air and the dreadful smell rising from the Thames chloride of lime was often used to cleanse the air and gutters.
