CD is "as ignorant of mechanics as a pig", but glaciers have interested him greatly. Hopes to hear that JT’s experiments with ice will explain the freezing together of ice below the freezing point.
Asks JH to keep memoirs JT sent with regard to JT's application for position at University of Sydney.
Remarks on physical properties of ice and their bearing on glacial phenomena. Asks for help inventing term for idea of 'fracture and renewal' of glacial bendings.
Thanks for papers on diamagnetism and lecture on 'slaty cleavage.' Compares with phenomenon of 'ringing coins' in mint. Explains with examples conformity of JT's views with JH's own on geological stratification. Praises simplicity yet completeness of JT's work.
Clarifies letter on motion and structure modification of glaciers. JH thinks glacier ice unfavorable for exhibiting JT's phenomenon [see JT's 1856-7-30].
Sends sketch of lecture on structure and motion of glaciers. Wants to conduct experiments on physical properties of ice, and applying polarized light. Beyond paper, is interested in cleavage of ice.
Thanks for lecture on glacier cleavage. Wonders how 'regelation' occurs when two masses of ice at 32° are placed in contact.
Sends memoirs on magnetism of crystalline bodies. Notes that remarks on atomic mechanism of Iceland spar contrast with JH's views expressed in JH's Light.
Agrees with and asks permission to publish JH's letter in the Philosophical Magazine. Is going to Switzerland and Tyrol, where hopes to see phenomenon of glacial descent [see JH's 1856-7-31].
Letter in application for Professorship of Experimental Philosophy and Chemistry at University College, Sydney.
