Does anyone know the name and poet of the poem with these lines?

Question:"I would find grievous ways to have thee slain, intense device, and superflux of pain; Vex thee with amorous agonies, and shake life at thy lips, and leave it there to ache; Strain out thy soul with pangs too soft to kill, intolerable interludes, and infinite ill"

I's from "Anactoria" by Charles Algernon Swinburne. I entered the first part in a search engine and found references on line, but didn't find a copy of the text. Any library should have a few copies of Swinburne--very freaky poet.
