NOTICE. 
Tue Roya Society of New South Wales originated in 1821 
as the ‘Philosophical Society of Australia”; 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” ; and finally, in May, 1866, by the 
sanction of Her Most Gracious Majesty the Queen, it assumed 
its present title.
