"DIAMAGNETISM" - half-title page of Tyndall's Researches on Diamagnetism and Magne-Crys…

JAN 01 1870

The half-title page of John Tyndall's 1870 volume: the single word DIAMAGNETISM set alone in the middle of an otherwise empty sheet of 1870 paper. The book collects two decades of Tyndall's work at the Royal Institution on diamagnetism and magnecrystallic action, including the long fight over whether diamagnetic bodies have a true polarity. As an image it is unusually clean - the word itself, in period type, with nothing else on the page.
