Lectures on calorimetry and the mechanical equivalent of heat, given by Ernest Howard Griffiths at the Philosophical Hall in Leeds and printed by Cambridge University Press in 1901 for physicists and students. Engraved line diagrams show calorimeters in section, mercury thermometers, stirrers and lagged vessels, a weight-driven friction apparatus, and a full-page wiring plan of bridges, coils and galvanometers with letter keys.
