appointed Attaché to the British Embassy in France, and subsequently Secretary to 
the Board of British Claims on the French Government, established at the peace of 
1815: in filling this office he spent several years in Paris, where he became 
acquainted with Cuvier and other distinguished scientific men. On his return to 
England he was promoted in 1825 to the responsible office of H.B.M. Commissioner 
of Arbitration to the mixed British and Spanish Court of Commission for the 
Abolition of the Slave Trade at the Havannah ; in 1830 Commissary Judge in the 
same Court and later Judge in the mixed Tribunal of Justice. After ten years’ 
residence in Cuba he returned to England in 1836 and in the year following he 
retired from the public service upon a pension. Until he finally left England he 
was an active member of the Zoological Society of London, then not long founded, 
and for some time he was a member of the Council. The change from a tropical 
climate to that of England proving detrimental to his health and comfort, Mr. W. 
S Macleay, influenced no doubt by favourable reports from Australia, decided to 
rejoin the members of the family there, and early in 1839 he arrived in New South 
Wales, where he spent the rest of his life. He died in Sydney on January 26th, 
1865, in his seventy-third year. 
Asamember of the Board of Trustees of the Australian Museum Mr. W. S. 
Macleay warmly seconded the efforts of his father ; and until ill-health compelled him 
reluctantly to retire, he is said to have been the life and soul of that Institution ; 
by his advice and able co-operation also the Act for the establishment and endowment 
of the Museum was introduced, and subsequently passed into law. He was for several 
years a member of the National Board of Education, and for a short period a member 
of the Executive Council during Sir William Denison’s administration, and before 
the imauguration of Responsible Government. 
He was the author of “Hore Entomologice, or Essays on the Annulose Animals” 
(1819-21), of the “Annulosa Javanica,” 4to (1825), of the “Annulosa of South Africa,” 
4to (1838), “A Catalogue of Insects collected by Captain King, R.N.” (1826), and of a 
number of important papers on various subjects which appeared in the Transactions of 
the Linnean and Zoological Societies, in the Zoological Journal, the Annals and Maga- 
zine of Natural History and other Journals. He did not confine his attention entirely 
to entomology ; but though he added extensively to the collection inherited from his 
father, and accumulated both notes and sketches, he did not after settling in Australia 
write much even on Australian topics. Four short papers contributed to the Annals 
and Magazine of Natural History [Vols. VIII. and IX. 1841-42], and one to the 
Tasmanian Journal of Science [ Vol. III. 1849], appear to be all that were published 
during his residence in New South Wales. In the latest but one of the former, an 
“Essay on the Natural Arrangement of Fishes,” sent as a letter to J. McClelland, 
Esq., and published in the Calcutta Journal of Natural History, July, 1841, after-
