158 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 
In 1871 he was appointed teacher to the Mining School established 
by the Cleveland Ironmasters, first at Darlington and then at Redcar, 
until in 1875 he obtained the post of Professor of Natural Science on 
the Elder Foundation at the University of South Australia in Adelaide. 
Here the serious work of his life began, and he worked at it with all 
his energy. In addition to his professorial duties he devoted himself 
to the advancement of science in the land of his adoption, and by 
his untiring efforts largely assisted in raising it to its present status. 
The ‘‘ Philosophical Society,” when he went out, was not altogether 
a flourishing body, but he persuaded others to join him in publishing 
original articles in its proceedings, instead of sending them to more 
widely known European journals, and so increase the utility of the 
Society, which, under his presidency (1878-80), became the ‘‘ Royal 
Society of South Australia.”” In all some ninety odd papers were con- 
tributed to its volumes by him; some few of these were on botany or 
general geology, and about thirty on recent mollusca, but the greater 
number were on the fossil mollusca of the Tertiary beds of the 
Australian Continent. Other papers of his on the same subject 
appeared in the Proceedings of the Royal Society of Tasmania, of 
the Linnean Society of New South Wales, and of the Australian 
Association for the Advancement of Science, of which he was president 
in 1893. Out of the 380 species recognized by Mr. G. F. Harris 
in his ‘‘ Catalogue of Tertiary Australian Mollusca in the British 
Museum,” 225 are species established by Tate, an index to the amount 
and value of his labours ! 
In the Autumn of 1896 he paid a visit to England, and contributed 
to the Proceedings of this Society a paper ‘‘On the discovery of 
a recent species of Arcoperna”’ (Proc. Malac. Soc., vol. ii, p. 181). 
He continued to work on with unflagging zeal until the Summer of 
1900, when heart trouble became serious, and he finally succumbed to 
the malady on September 20th. His very last work was ‘A revised 
Census of the Marine Mollusca of Tasmania,” undertaken in association 
with Mr. W. L. May (Proc. Linn. Soc. New South Wales, 1901, 
pt. 3), of which he was only able to finally complete the first 24 pages, 
the task of seeing the rest of the work through the press devolving on 
his co-author, assisted by Mr. C. Hedley. 
A full list of his scientific writings will be found appended to the 
memoir of him by Professor Blake (Geol. Mag., 1902, p. 87), to which 
we are mainly indebted for the foregoing details. 
Wirt1am Manon Daty was born in the early sixties on the Shevaroy 
Hills in the Madras Presidency, India, where his father was the owner 
of a coffee plantation. The son was brought up in India, and in time 
succeeded, with his elder brother, to the management of his father’s 
estate. This he left about 1895 to take charge of a coffee plantation 
in the Kadur district of Mysore, where he obtained the specimens 
of the new genus Dfulleria, named in his honour JL Dalyi, by 
E. A. Smith (Proc. Malac. Soc., vol. iii, p. 14).1. In 1898 he received 
1 The anatomy of this species was described later (Proc. Malac. Soc., vol. iii, p. 87) 
by the late Martin F. Woodward, from specimens obtained by Mr. H. Bonner.
