Prince Napoleon again tried it on his yacht in the spring of 1867, and it proved to be so advantageous for traveling at night and for signaling that, after some further experimentation, it was installed permanently; a frigate of the French navy's Mediterranean fleet and the transatlantic passenger liner St. Laurent were equipped with the Alliance 58 Richard, op. cit.
