Famous quotes containing the word heart:
“This letter will be delivered to you by my child,the child of my adoption,my affection! Unblest with one natural friend, she merits a thousand. I send her to you innocent as an angel, and artless as purity itself; and I send you with her the heart of your friend, the only hope he has on earth, the subject of his tenderest thoughts, and the object of his latest cares.”
—Frances Burney (17521840)
“Handsome husbands often make a wifes heart ache.”
—Samuel Richardson (16891761)
“Twelve oclock! It is the natural centre, key-stone, and very heart of the day. At that hour, the sun has arrived at the top of his hill; and as he seems to hang poised there a while, before coming down on the other side, it is but reasonable to suppose that he is then stopping to dine; setting an eminent example to all mankind.”
—Herman Melville (18191891)
