Air and Odour

Starting with the poet Samuel Taylor Coleridge’s experience of the Royal Institution lectures of 1802, this chapter sets out the relationship between smell, chemistry, and environmental medicine in the period from the 1660s to the 1820s. Putridity and putrefaction had long been associated with bad smell, but what the chemical investigations of the mid-eighteenth century succeeded in doing was separating the stink of putridity from its unhealthy qualities. Eudiometers, devices for measuring the quality of air that enjoyed a short vogue in the later eighteenth century, were one way of replacing the, now untrustworthy, sense of smell. Ultimately smell became a useful analogy for thinking about airborne disease or contagious particles, but by the early nineteenth century most physicians and chemists no longer believed that all smell was disease.
