Famous quotes containing the words magic and/or number:
“I revere the memory of Mr. F. as an estimable man and most indulgent husband, only necessary to mention Asparagus and it appeared or to hint at any little delicate thing to drink and it came like magic in a pint bottle; it was not ecstasy but it was comfort.”
—Charles Dickens (1812–1870)
“While I do not suggest that humanity will ever be able to dispense with its martyrs, I cannot avoid the suspicion that with a little more thought and a little less belief their number may be substantially reduced.”
—J.B.S. (John Burdon Sanderson)
