Not in Denucé. Perry (1833-1889) attended various colleges before taking up a position at Stonyhurst, where he also ran the observatory. He took part in several scientific expeditions, undertaking meteorological, magnetical, and astronomical work in France, Spain, the West Indies, Kerguelen (to observe the 1874 transit of Venus), and the Iles du Salut off French Guiana, where he died of fever. He published several reports on his findings, all of them rare; the present work, which provides an overview of his life and work, is also uncommon.
