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 to gain any really clear idea as to the princi- ples involved or as to their meaning 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 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. This is mainly be- cause my teaching work prevents  me from reading very much of what is written by others. I have been in Berne several times. My wife 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. 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 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. Einstein Bern Switzerland.," and post- marked "Cambridge 9:30 PM My 20 09." Footnotes 4-7 and 9-10 record translations of certain words in the text in an unknown hand. They may have been prepared for Einstein's use. George Frederick Charles Searle (1864-1954) was Lecturer in Experimental Physics at the University of Cambridge. Alfred Bucherer. Probably the review article Einstein 1907j (Vol. 2, Doc. 47). "ermudet" interlineated. "weit" interlineated. "Bedeutung" interlineated. "Beschreibung" interlineated. Searle had recently worked on such topics as the thermal conductivity of indiarubber (.Searle 1901a) and phenomena connected with suddenly accelerated or decelerated electrified systems (Searle 1907b, 1907c, 1908). "hauptsächlich" interlineated. "verhindert" interlineated. Alice Mary Searle. Mürren (1636 m) and Grindelwald (1034 m), both in the canton of Bern. Oliver Heaviside (1850-1925) was a Fellow of the Royal Society and carried out his re- search activities independently of any institution.
