1st. The most successful patentees have been Bethell and Burnett, in England; and Boucherie, in France: all B’s.
2nd. The most successful patents have been knighted. Payne’s patent was, we believe, used by Sirs R. Smirke and C. Barry; Kyan’s, by Sir R. Smirke; Burnett’s, by Sirs M. Peto, P. Roney, and H.
