The notebook contains observations made by De la Caille at the Cape and elsewhere; a list of expenses in connection with his observatory at St. Martin (Paris); and details of the mathematical basis for his calculations, including lists of formulae and trigonometrical proofs, used as an aide-memoire during his travels. There are calculations of some star coordinates, apparently made at the Cape, and, most important of all, a calculation of the difference in latitude between the Cape and Klipfontein for his determination of an arc of the meridian.
Court proceedings in the trial State vs Abram Fischer.
Abram Fischer was arrested on the 11 November 1965 and put on trial in March 1966 on charges of furthering the aims of communism and conspiracy to overthrow the government. Judge Boshoff found him guilty of these charges and sentenced Bram Fischer to life imprisonment.
Also included in the collection is the reprint of Bram Fischer's statement from the dock on the occasion of a colloquium, held on the 26 March 2015 at the University of the Witwatersrand, in honour of Bram Fischer. At the same event the University bestowed an Honorary Doctorate on Abram Fischer.
The letters are interesting, not only giving a good picture of the work of the Anglican church in various parts of Africa but also fore-shadowing some of the political problems which have arisen in Africa such as the racial friction between black and white, the colour bar in South Africa and the church's attitude to it and the question of the native franchise. From the letters it appears that there were problems common to the various dioceses such as the shortage of clergy, need for more money, the importance of educating the African and training African priests and the difficulties of working in vast areas where parishes were scattered.
