|Copy letter from Robert William Frederick Harrison, to Horace Darwin, Fellow of the Royal Society
|17 June 1905
|Has Darwin's note of yesterday about Fery Radiation Pyrometers but there is no description enclosed and it does not seem to have come by separate post. Asks for as full as possible particulars of the nature of the exhibit and requirements for showing the instrument in operation. The Society's direct current if 105 volts but they have alternate current also.
