NOTICE, 



The Royal Society of New South Wales originated in 1821 as 

 the "Philosophical Society of Australasia"; after an interval of 

 inactivity, it was resuscitated in 1850, under the name of the 

 " Australian Philosophical Society," by which title it was known 

 until 1856, when the name was changed to the "Philosophical 

 Society of New South Wales"; in 1866, by the sanction of Her 

 Most Gracious Majesty the Queen, it assumed its present title, 

 and was incorporated by Act of the Parliament of New South 

 Wales in 1881.
