A popular scientific treatise on spectrum analysis by the German schoolmaster Heinrich Schellen, translated by Jane and Caroline Lassell and annotated by astronomer William Huggins for English general readers in 1872. Wood-engraved spectra fill black fields with fine vertical line rulings and stipple gradients, alongside a stippled total eclipse showing corona and prominences, and labelled element line charts.
