Definition of "felicific"

Has conduct worth in and for itself, or only as its consequences are felicific as regards the social welfare?

1895, John Grier Hibben, “Automatism in Morality”, in International Journal of Ethics, volume 5, number 4, page 467

1980, Philip Drew, “Jane Austen and Bishop Butler”, in Nineteenth-Century Fiction, volume 35, number 2, pages 141–142

The Langham is proof of the felicific power of good architecture, the power to promote, both in its inhabitants and in passers-by, happiness.
