|Copy letter from Robert William Frederick Harrison, to Herr Professor Drygalski, Deutsche Sudpolar-Expedition, Luisenstrasse 33/34, Berlin, N.W.6.
|19 January 1906
|Harrison, further to their earlier correspondence on the requested loan of 'Observations on days of unusual magnetic disturbence made at the British Colonial Magnetic Observatories' published in 1843, has heard from the Stationary Office that they do not have any spare copies. As the only available copy is in the Royal Society Library, Harrison lacks the power to send it to Drygalski. However, if the table which he refers to is the only section he requires, Harrison offers to make a copy of that table and send it to him.
