Obituary notices of fellows deceased

In Alexander John Ellis the Society have lost an earnest and useful worker in several important branches of knowledge. He was a learned mathematician, an accomplished scholar, an original thinker, an indefatigable investigator, and an industrious writer; and his contributions to some of the more obscure and unfamiliar subjects of scientific study bave been numerous, varied, and remarkable. He was born at Hoxton in 1814, and bis original name was Sharpe, having been changed to Ellis in 1825. It is believed that this was done in consequence of a bequest, made by a relative, to enable him to devote his life to study and research, unhampered by pecuniary cares; and if this was so, be certainly carried out most faithfully his part of the bargain.
