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. 



CLARKE MEMORIAL LECTURES. 



The three Lectures on the " Geology of Australia " which were 

 to have been delivered to the Members of the Royal Society of 

 New South Wales in November, 1889, have been further post- 

 poned owing to the absence of Mr. C. S. Wilkinson, f.g.s., 

 Government Geologist, in England on Departmental business.
