Abstract
THE immersion paraboloid illuminator exhibited at the recent soirée of the Royal Society as designed by me, proves to have been anticipated in principle and construction by Dr. John Barker, of Dublin, from whom a paper on the subject will be found in the Proceedings of the Royal Irish Academy for 1870.
