Emblazoned arms of British rulers and nobles, in chronological order, beginning with a noble who "came to England w[i]th w[illia]m Conquerer" through one created Earl "sondaye the 23th [sic] of october in the yeare of our Lord god 1597." Each entry features a shield painted with arms; a short account of the bearer's entry into England, notable achievements, famous ancestors/descendants, and investiture into peerage (secretary hand in dark brown ink); and a blazon (later italic hand in black ink). Monarchs' arms represented larger than others,' and centered on page, without descriptions.
