Letter from [James] Howard Gore, Columbian University, Washington DC, to Herbert Rix 'My dear Sir, I am pleased to say that the box containing Colonel Herschel's Bibliography of pendulum operations arrived safely and in good shape. I have already begun the examination of them, and hope to be able to return them next week, I have informed President Welling of their arrival and shall notify you when I start them homeward. Please accept my sincere thanks for your promptness in complying with Colonel Herschel's request. Very sincerely'. 29 April 1889
