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”; and finally, in 1866, by the 
sanction of Her Most Gracious Majesty the Queen, it assumed 
its present title.
