Now, though it was permissible for the Archdeacon to be also the Andrews Professor, yet when the Archdeacon became a Bishop it was understood that he should transfer his residence from the Observatory to the Palace. The Chair of Astronomy accordingly became vacant. Brinkley’s subsequent career seems to have been devoted entirely to ecclesiastical matters, and for the last ten years of his life he did not contribute a paper to any scientific society. Arago, after a characteristic lament that Brinkley should have forsaken the pursuit of Science for the temporal and spiritual attractions of a Bishopric, pays a tribute to the conscientiousness of the quondam astronomer:-- “A partir du jour ou il fut revêtu de l’episcopat, l’homme dont toute la vie avait été consacrée jusque-là à la contemplation du firmament et à la solution des questions sublimes qui recèlent les mouvements des astres, divorca complétement avec ces douces, avec ces entraînantes occupations, pour se livrer sans partage aux devoirs de sa charge nouvelle, afin d’échapper, je suppose, à la tentation, l’ex-Directeur de l’Observatoire Royal d’Irlande, l’ex-Andrews Professor d’Astronomie de l’Université n’avait pas même dans son palais la plus modeste lunette. On doit la révélation de se fait presque incroyable, à l’indiscrétion d’une personne qui s’étant trouvée chez l’évêque de Cloyne un jour d’éclipse de Lune, eut le déplaisir, faute d’instruments, de ne pouvoir suivre la marche du phénomène qu’avec ses yeux.” The good Bishop died on the 13th September, 1835. He was buried in the Chapel of Trinity College, and a fine monument to his memory is a familiar object at the foot of the noble old staircase of the library. The best memorial of Brinkley is his admirable book on the _Elements of Plane Astronomy_. It passed through many editions in his lifetime, and even at the present day the same work, revised first by Dr. Luby and more recently by the Rev. Dr. Stubbs and Dr. Brünnow, has a large and well-merited circulation.
