After sympathizing with him on his indisposition he writes: ‘I always felt that you really had more advanced views on politics than most of the Generals in the British Army, and what you say in your letter does not surprise me therefore in the least.’ He ends with regards to Lady Hart and the Harts’ daughter. Autograph postscript: ‘Ps. Ps. forgive type written letter.’

The Bristol Aeroplane Company was an early and important innovator in the field of aircraft design and development. Four variants of its Titan engine (I, IIF, II Special, and IV) were produced in 1928. The present brochure and photographs are contained in a large manila envelope, with 'The "Bristol" Aeroplanes' printed in green on front. The photographs are all in very good condition, and all measure around 18 x 23.5 cm. The brochure is 4pp., 4to, printed in brown on a bifolium of cream paper. It is in good condition, with a little wear and creasing.

26pp., 12mo. Stitched. In remains of original printed wraps. On aged paper, in chipped wraps, with several leaves loose. An important work in the history of eronautics by one of the great experimental physicists of the nineteenth century. Excessively scarce: no copy of this offprint in the British Library or on COPAC. 'In this lecture Rayleigh discusses the method of calculating the mechanical forces on a plane presented obliquely to a current of air, so far as this can be done. At best, the calculation is very incomplete.

8vo bifolium: 4 pp. On art paper. Unbound. On aged and creased paper. Clear and complete. Arranged as a magazine article, with the text in two columns. Six photographs of the exterior and interior of the plane. Two diagrams, including one full-page and extremely detailed cross-section, captioned 'The Bristol Bombay Bomber-Transport | (Two 1,010 h.p. Bristol Pegasus XXII motors).'

One of the letters is 4to, 2 pp; ten are 4to, 1 p; and one is foolscap, 1 p. The collection is in good condition, on lightly aged paper. Many of the letters are docketed and most bear the Society's dated stamp. Written in the capacity of Secretary of the Aeronautical Society, and editor of its 'Official Organ - The Aeronautical Journal'. Topics include the hiring of the Royal Society's hall for two series of talks to the Aeronautical Society. Faraday also discusses the details of a lecture by 'Mr.

Octavo, 48 pages. Stapled. In faded original orange printed wraps. Nine pages of illustrations, including three on wraps. Good, on aged high-acidity paper. Wraps a little stained. Unobtrusive ownership inscription at head of front wrap. Illustrations include two full-page balloons and 'A modern sea-plane: the Burgess-Dunne type'. Twelfth illustration (diving English biplane) on front wrap. Scarce: no copy on Copac.

Novelist and writer on aeronautics (1885-1968). All items one page, quarto. As a whole good, though grubby, but some items with pin holes, closed tears, etc. Most bearing the R.S.A. stamp and some docketed. Three items with enclosures. The items are dry communications relating to the arranging of R.A.S. lectures at the R.S.A.

Historian of aviation (1909-81) at the Victoria & Albert Museum, London. Eight items, various formats. Very good. LETTER ONE (two pages, octavo, 14 January 1949, on V & A letterhead): 'As a very new fellow of the Society I hesitate to burden you with reading the enclosed [an article on 'Father Gusmao: the first practical pioneer in aeronautics', not present], but I thought there might be some chance of its appearing in the Journal. It is too historical for the Roy. Aeronautical Society's Journal and too aeronautical for the others, so I am stuck!
