Publication details:
Note dated 11 March 1944. Note and calculastions on letterheads of Imperial College of Science and Technology, London.
All three items fair, on aged and creased paper. Slight rust-spotting at head of note, and short closed tear to leaf of calculations. Note (12mo, 1 p): He is enclosing 'a few figures' and hopes they are what Dingle wants. The calculations (4to, 2 pp) begin with working out of the 'Annual coal production in world' in therms. This is followed by similar figures for 'Petroleum' and 'Natural gas', giving the 'Total fuel (bar wood and peat) used per annum in the world'.
