102 THE VICTORIAN NATURALIST. 



C. Frost, F.L.S., and C. French, F.L.S. — who reported interesting 

 outings, but, as a rule, owing to the extreme dryness of the 

 spring, a great scarcity of noteworthy specimens. 



The chairman reported that a practical meeting had been held 

 on 26th October, when Mr. W. Stickland gave a demonstration 

 on " Desmids, their Study and Classification," which proved 

 most instructive to those present. 



ELECTION OF MEMBERS. 



On a ballot being taken, Miss A. Bell and Dr. C. Ryan 

 were duly elected members of the Club. 



PAPERS READ. 



1. By Mr. T. S. Hall, M.A., entitled "On Some Recent 

 Work on the Tertiary Rocks near Melbourne." 



The author gave a brief historical account of the work 

 that had been done on the Tertiary rocks near Melbourne, and 

 said that Dr. Selwyn's early work in 1854 laid the sure 

 foundations on which his successors had built ; he had correctly 

 indicated the sequence of the various beds, and for a part of the 

 area his map is the only one, on a large scale, that we possess. 

 Mention was also made of Aplin and Norman Taylor, Selwyn's 

 earliest assistants. The pala^ontological work of Sir Frederick 

 M'Coy, and of Professor Tate and others, was touched upon, 

 and the corrections made to the geological maps by Brough 

 Smyth were alluded to. 



The geological structure of the metropolitan area, as recently 

 described before the Royal Society of Victoria by Messrs. Hall 

 and Pritchard, was rapidly sketched ; and evidence was given for 

 supposing that granite exists over a wide area in the district 

 under the tertiary cover. Counting this granite, which is no- 

 where exposed, the following sets of rocks occur within ten miles 

 of Melbourne : — 1. Estuary beds and raised beaches. 2. Upper 

 volcanic. 3. Marine and freshwater miocene. 4. Marine 

 eocene. 5. Older volcanic. 6. Lower leaf-beds and brown 

 coals. 7. Upper silurian. 8. Granite. 



The quarter sheets of the Geological Survey, sections and 

 sketches, were exhibited in illustration of the remarks. 



Mr. G. Sweet, F.G.S., questioned the correctness of the 

 conclusions arrived at by Mr. Hall, especially with reference to 

 the sections exposed on the Moonee Ponds Creek, between 

 Ascot Vale and Brunswick. 



Mr. J. G. Luehmann, F.L.S., Acting Curator of the Melbourne 

 Herbarium, read the first of a series of articles, entitled 

 " Reliquiae Muellerianse : Descriptions of New Australian Plants 

 in the Melbourne Herbarium," in which he described a new 

 Acacia, A. Ti/soni, from the Upper Murchison River, Western 

 Australia.
