... The then president of the Society, Mr. Robert Burke, appointed a committee of eight or ten members, most of whom had made smaller mirrors, as an instrument committee, with Mr. Thorpe as chairman. ... Seriously, the best practicable solution seemed to be to build a machine to do the grinding and polishing. ... It was decided to grind the edges of the mirror to make it truly circular, as the rough cast glass was some 3/8 inch longer on one diameter than on the other. ...
