5pp., 8vo, with five plates. Stitched. In brown printed wraps headed 'Compliments of the Author', with 'Reprint from Popular Astronomy' at foot. Heavily aged, in worn and stained wraps repaired with tape. At the head of the cover Lowell has written 'iss Mary E. Proctor'. Manuscript note in another hand (presumably Procter's) on cover: 'Contains a note in Lowell's own handwriting on page 2'. Lowell's autograph note on p.2, with slight loss due to trimming of the edges of the pamphlet, reads: 'For further story by me see Jan. '97 pular stronomy'.

A Fellow of the Royal Society, Marlborough's main scientific interest was astronomy, a subject on which he corresponded with von Brühl. The four items in good condition, with light signs of age and wear.

Exhibitors include Sir Oliver Lodge, Sir William Crookes, Rutherford and Soddy ('The condensation of the radio-active emanations of radium and thorium by liquid air.') and the Solar Physics Observatory, South Kensington.

The collection of six items, with an envelope, is in good condition. An interesting sidelight into 1930s business practice, and an insight into an unusual business concern.

Constructional Engineers, confirming a verbal order 'for the installation and supply of lightning conductors' to 2 Orchard Rise, Sheen Common Drive, East Sheen.
