Notebook on logarithms, ca. 1714-1718, 1747

This notebook is missing at least one page, as it begins in the midst of a problem. It contains extensive notes on logarithms and various related examples, problems, and calculations. Prince made notes on the addition, subtraction, multiplication, and division of logarithms, as well as some notes on navigation. The last two pages of this notebook contain a draft of a letter from Prince to an unnamed gentleman in London, thanking him for his financial support. This is believed to have been written in June 1747, when Prince arrived in Portsmouth, England "without one six pence in [his] pocket & without Hat, Coat, Breeches, Shirts, Stockings or shoes fit to come up to London with." In the letter, he thanks this donor for his support and describes in detail his situation and the challenges facing him in leaving the Navy and beginning missionary work. He refers several times to Dr. Philip Bearcroft, the Secretary of the Society for the Propagation of the Gospel, who was responsible for his approval as a Missionary to the Moskito tribe.
