Fletcher, Dendy, and Tryon have worked on worms and 

 the interesthig Perpatus ; and Thomas Whitelegge published in 

 1889 a work on the " Marine and Freshwater Invertebrate Fauna 

 of Port Jackson and the Neighbourhood." 



Mr. Saville-Kent, one of our Past Presidents, did valuable 

 work on oysters, corals and fish during his stay in Brisbane. 



Mr. Pound's investigations on lower animal forms, like the 

 tick, are known beyond the colony. 



The development of mineralogical knowledge of Australia 

 depended mostly on the geological survey and on the mmes. 

 Queensland got a catalogue of minerals in 1887 by our late 

 friend, Mr. E. B. Lindon, who studied mineralogy in England 

 and had been analyzing in Brazil for some years. The arduous 

 young man came to an untimely end by a rotten rope to which 

 he trusted going down a miserable gold-claim. The rope broke 

 and Mr. Lindon was killed — it is to be feared, not instantan- 

 eously. The catalogue contains 97 different minerals, and was 

 compiled chiefly from his own knowledge and the reports on 

 geology by Messrs. Gregory, .Jack, Rands, Daintree, and A. W. 

 Clarke. In 1888 Professor Liversidge, in Sydney, published a 

 splendid work on minerals of Nevv South Wales. 



In 1890 a mineral census of Australasia appeared in the 

 report of the committee of the Australasian Association for 

 the Advancement of Science. Only 75 minerals are mentioned 

 from New South Wales by Professor Liversidge, as he intended 

 to give merely a supplement to his catalogue of 1888. 



Mr. Cloud, basil g on reports by Goyder, Professor Tate, 

 and Professor Uliich, enumerates exactly 100 different minerals 

 from South Australia, and the Queensland catalogue, worked out 

 by Messrs Jack, Lind )n, Rands, and Maitand, contain 101 

 different ones. In this way not many more than 100 different 

 minerals have been recorded from Australia. As our school 

 book (Professor Kobell's tables for determination of minerals) 

 contains on 107 pages not less than 680 different ones, it is 

 clearly to be seen how muL-h can still be done in this field by 

 careful investigation and analysis. 



The development of topographical knowledge, of course, 

 preceded that of geology. Oxley, in 1817, was the author of 

 the first topographical map of New South Wales ; whereas Dean
