NOTICE. 
Tue Royat 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.
