Letter from H M [Hector Munro] Macdonald, 52 College Bounds, Aberdeen, to [Joseph] Larmor He has the questions, but like Oliver he asks for more thermodynamics and kinetic theory. He gathers that some of the information from candidates is in next term's lectures from Larmor. Macdonald thought of setting a mixed question based upon [Max] Planck's result on temperature of an enclosure moving at uniform velocity and one at rest. He asks if he should attend the meeting of the Government Grant Committee, or if business is only formal. He has a 'pretty formula' for a circular disc under the influence of any inducing system symmetrical with its axis. This is a single integral and is easy to verify and he is thinking of setting it. 12 March 1909
