iron cssed ships Of the French navy, with the exception
OF formidable frgaes and two shipe-o the line,

many unfsvorable chances as the Warrior.
After very minute description OF these two floating
fotresses Admiral Paris points out 10 the reader the
merits each ship and describes at length
all cased ships built 10 the date OF his cook in
the United Kingdom and In America.
One OF the questions the Admiral examines with gret
care is tho mateao which roncased ship ought be
constructed and ne TO decide In favor OF timber,
though the question says, not settled The advan
