NOTICE. 
THE Roya Socirty 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. 
TO AUTHORS. 
Authors of papers desiring illustrations are advised to consult 
the editors (Honorary Secretaries) before preparing their drawings. 
Unless otherwise specially permitted, such drawings should be 
carefully executed to a large scale on smooth white Bristol board 
in intensely black Indian ink, so as to admit of the blocks being 
prepared directly therefrom, in a form suitable for photographic 
“‘process.” The size of a full page plate in the Journal is 44 in. 
x 6#in. The cost of all original drawings, and of colouring plates 
must be borne by Authors.
