We have all become so accustomed to hearing the term "A-l" used to designate a thing as perfect that it does not occur to many of us to wonder how' it originally came to be used in that connection. Its first use was as a symbol in the code by which vessels were graded in the register of shipping kept by Lloyd's, the originators of marine insurance. "A-l" was the best rating given to the highest class vessels, "A" standing for perfect condition of the hull of the ship and "1" meaning that the rigging and whole equipment was complete and in good order.
