At front of book, notes on Latin grammar and mathematics, in a young hand. At rear of book, notes on trigonometry, in a young hand. In centre of book, notes and diagrams on light, crystallography, polarisation, in Hodgkin's later hand. Work breaks off. Possibly 1930. This may have been begun Mar. 1927-Spring 1928 after School Certificate and during preparation for Somerville College Oxford (Ferry pp.32-33).

The book is numbered '2' but no other numbered books have been found. Physics experiments, class exercises, some marked by tutors, H.B. (?Herbert Bowman), R.T.L. (R. Lattey), others unidentified.

History of chemistry (perhaps from lectures), tests, experiments, techniques. Both ends of book used.

Experiments, analyses, calculations. Both ends of book used. Some pages in another hand.

Notes, experiments, calculations on physical properties, surface tension, inertia, projectiles, viscosity etc. One page has headnote 'Lecture 5'. Both ends of book used. At rear of book, loose pages in another hand.

Probably lecture notes on history and properties of substances. Both ends of book used.

Notes on chemistry, from lectures or perhaps Hodgkin's own reading.

Notes, perhaps from lectures, on kinetic theory of gases, radioactivity, α rays, early atomic physics. Not all of book used.

Experiments, analyses, practicals. At rear of book, miscellaneous calculations.

Experiments, calculations, some notes in another hand. Not all of book used.

At front of book 'List of experiments done', on density, properties of liquids, molecular volume, vapour pressure etc. At rear of book miscellaneous calculations and some loose pages.
