The notes are in ink and pencil, and pages are numbered 1-101. There is a manuscript index on verso of the fly-leaf, with subjects listed alphabetically. Some of the pages are dated, ranging from July-September 1913.

The volume is lettered on front cover: 'PHYSICS DEPARTMENT. THE LEEDS UNIVERSITY.' Bookplate for the University of Leeds Library inside the front cover, with ‘The gift of Sir Lawrence Bragg 1945’ in typescript.

There are two press-cuttings attached to fly-leaf, describing the ceremony of unveiling a tablet in the Brotherton Library to commemorate the work of the late Sir William Bragg and his son, on 20 July 1945. The first press-cutting is from the Yorkshire Post and Leeds Mercury, dated 21 July 1945. The photograph shows Sir Lawrence Bragg, Colonel C.H. Tetley (Pro-Chancellor), Professor R.Whiddington, and B. Mouat Jones (Vice-Chancellor), in front of the tablet. The article describes how the tablet was a gift from the wife of Professor Arthur Smithells, former Professor of Chemistry at the University of Leeds and friend of Sir William Henry Bragg.
