The publications of the Hakluyt Society (founded in 1846) made available edited (and sometimes translated) early accounts of exploration. The first series, which ran from 1847 to 1899, consists of 100 books containing published or previously unpublished works by authors from Christopher Columbus to Sir Francis Drake, and covering voyages to the New World, to China and Japan, to Russia and to Africa and India. This volume, first published in 1847 and revised in 1870, consists of letters of Christopher Columbus to the Treasurer of the King and Queen of Spain, describing his first, third and fourth voyages, and a letter from Diego Alvarez Chanca, a royal physician who went on the second voyage and reported his experiences to the town council of Seville. In this edition by R. H. Major, the letters are given in the original languages with an English translation, editor's preface, explanatory notes and index.
