an English publisher and amateur astronomer. After a number of years of achieving considerable success in daguerrotypy, he worked on telescopic and microscopic observations. In 1852 he built an observatory at Claybury, in Essex, in which a 6-inch refractor was mounted equatorially. In 1854 he designed the diagonal eye-piece for observing the whole of the Sun's disc without contraction of the aperture of the object-glass, a description of which appeared in the Monthly Notices of that year.
