Ivory and the Royal Society

In total Ivory presented 15 papers to the Royal Society and received 3 medals.

His first paper was in 1809, and he gave 3 more before he was elected a member in 1815. His papers were generally regarded as elucidating and innovative although he is considered to have unfairly criticised Laplace over a portion of Mécanique Céleste. His papers continued reasonably regularly until his last in 1839, at the age of 74.

The medals Ivory received were the Copley, in 1814, for his contributions to the Philosophical Transactions, and two Royal Medals, in 1826 and 1839, for papers on astronomical refractions (nos. 6 and 14 in the list of his papers to the Royal Society). The latter paper was the Bakerian Lecture for 1838.
