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.

This collection of correspondence (1-8) was written between various individuals in South Africa, Germany and England. The letters and their writers provide a glimpse into the wide network of Nazi and Anti-Jewish alignments and associations between Europe and Southern Africa, which existed prior to World War II and continued in post-war years. It includes the following:

Beamish had wide connections to the German Nationalist Party (Nazis) and its leaders, gave talks about the 'threats from International Jewry' and was the founder of the Britons Publishing Company. He published "The Jews' who's who: Israelite finance: its sinister influence" in 1921. He lived in Southern Rhodesia.
