He joined his See also:elder See also:brother See also:John in carrying on the business of making mathematical See also:instruments in See also:Fleet See also:Street, See also:London, and continued it alone after his brother's See also:death, until in 1826 he took W.

He also made transit instruments, equatorials, &c.; but his failure to construct an See also:equatorial mounting of large dimensions, and the consequent lawsuit with See also:Sir See also:- JAMES
