Wishes luck but expresses inability to help with new science journal [see JT's 1864-11-18].
Surprised that JT cannot obtain heat spots [see JT's 1864-11-14]. Describes glasses and lenses used.
Thanks for and comments on papers on scientific history and molecular physics, particularly on a magnetic experiment and on dynamical efficiency of coal relative to motion theory of light and heat. Comments on nature of heat, 'vis viva.' Deplores laxity with which physicists use and confuse terms 'force,' 'motion,' and 'energy.'
