Thomas Sergeant Hall. 131 



meeting in 1902, delivering an address on " The Possibility of 

 the Detailed Correlation of Australian Formations with Those 

 of the Northern Hemisphere " — a subject to which he had 

 devoted much attention. During the recent visit of the British 

 Association in 1914 he was local secretary of the zoological 

 section, and his wide general knowledge of Australian zoology 

 and geology enabled him to be of great service to many of the 

 visiting overseas members. 



Not the least of his services to science in Victoria was the 

 publication in 1899 of the " Catalogue of the Scientific and 

 Technical Periodical Literature in the Libraries of Victoria." 

 It required a man possessed of his general knowledge and 

 capable of his patient, accurate, and methodical work to 

 prepare this. In 191 1, assisted by Mr. E. R. Pitt, of the Public 

 Library, he issued a second and much enlarged edition. 



To readers of the Argus and Australasian he was well known. 

 Under the name of " Physicus " he contributed the column 

 of " Science Notes " to the latter for many years, and in 1905-6 

 published a series of popular geological articles in the former. 

 These, which are models of scientifically accurate writing couched 

 in the simplest language, he brought together and published in 

 1909 under the title of " Victorian Hill and Dale." 



He was keenly interested in all that referred to the fauna of 

 Australia, and took a leading part in securing the reservation 

 of Wilson's Promontory as a National Park ; in fact, it was 

 towards the end of 1914, during an official visit to the Park of 

 the Committee of Management (of which he was an active 

 member), that the first signs of his serious illness became apparent. 



In the Field Naturalists' Club his work has been of the 

 greatest service. He joined it in 1888, and when he was 

 appointed to the University post in 1893 began at once to take 

 an active part in the work of the Club. From 1895 onwards 

 he was a member of its committee ; from 1897-1900 he was 

 vice-president, and from 1901-1903 he was president. After 

 retiring from the presidency he still retained his active con- 

 nection with the Club, serving as memb'er of the committee 

 until 10,10, when he withdrew in order to give place to younger 

 men. This did not in the least mean that he had lost interest 

 in the work of the Club, whose meetings he continued to attend. 

 In fact, as recently as July, 1915, when, after some months of 

 illness, he thought that he was on the road to recovery, he 

 undertook to act as leader of a party of members visiting the 

 biological laboratory and museum in the University. This was 

 his last official connection with the Club, and when it was over 

 he realized the fact that he was no longer capable of work of 

 this kind, and he very much appreciated the resolution passed 

 by the Club in September last, at the suggestion of Mr, F. G. A.
