Andrew Smith & Son’s May 16-17 sale in Winchester will include three volumes of handwritten notes from the chemistry lectures of Dr Joseph Black (1728-99).

They were written up by George Buchan-Hepburn, who would later become a significant landowner and judge Sir George, 1st Baronet.

The notes in each book highlight Black’s series of lectures during the last six months of 1775, starting with the premise that: ‘Chemistry is the effect of heat’, a subject studied by Black since his work on latent heat in 1761. Black discovered magnesium in 1755-56, but perhaps his greatest legacy was the attention paid to his work by Lavoisier during his experiments leading to the establishment of quantitative analysis and the conservation of mass. Black was professor of chemistry at both Glasgow and Edinburgh universities from 1756-66.

Estimate £1000-2000.
