DOCUMENT 162 MAY 1909 191 quite well in a few days. I had hoped to make a careful study of the paper be- fore writing to you, but I have not been able to do so. I have not been able so far[5] to gain any really clear idea as to the princi- ples involved or as to their meaning[6] and those to whom I have spoken in England about the subject seem to have the same feeling. I think it would help us if you were to write a short account[7] of the subject which could be translated and published in some English journal,-the Phil. Mag. perhaps. If I could give any assistance in the matter I should be glad to do so, but I must say that I am not an expert in German. I send a few papers which I hope you will accept. They are on my own lines and have very little reference to the work of others.[8] This is mainly[9] be- cause my teaching work prevents [10] me from reading very much of what is written by others. I have been in Berne several times. My wife[11] and I were there for one night in Sep 1907. For the first time I saw the Alps perfectly clear. I thought they looked almost more beautiful at that distance than from Mürren or Grin- delwald.[12] If I find myself at Berne again, I hope I may have the pleasure of meeting you. I was recently at Torquay and had several conversations with Dr. Oliver Heaviside[13] on electrical matters. I think he would be interested to have a copy of your paper. His address is Homefield Lower Warberry Road Torquay. With renewed thanks for your paper I remain yours truly G. F. C. Searle. ALS. [20 472]. The envelope is addressed to "Prof. A.
