Letter from John M Govdell, Editor of the Engineering Record, 114 Liberty Street, New York, to the Secretary of the Royal Society 'My dear Sir:- The account in "Engineering" of Aoril 20, of the experiment of Messrs. Hill and Greenwood with high air pressures, is so very interesting and important, that I write to ask if you will be good enough to let us have a copy of their paper before the Royal Society for republication in the Engineering Records. Very truly yours, John M Govdell'. [For reply, see related records]. 5 May 1906
