BIOGRAPHICAL MEMOIR. 
completion of his gigantic enterprise. The work was therefore stopped 
after the appearance of part 2 ; and these two cancelled parts of Gould’s 
‘ Birds of Australia ’ are among the rarest of his w r orks. 
Gould left England in May 1838 and returned in August 1840, 
after exploring Van Diemen’s Land, Bass’s Straits, South Australia, and 
New South Wales, into the interior of which country he penetrated 
to the distance of nearly four hundred miles from the coast-line. 
300 species were added to the list of the Australian Avifauna by this 
adventurous journey of Gould and his assistants. Gilbert, who had 
worked under him at the Zoological Society, was sent by Gould to 
the western and northern parts of Australia and discovered many 
novelties. He then revisited England in September 1841, after two 
years of labour in the field, and returned to Swan Biver in the spring 
of 1842 ; and on the 28th of June in the same year he was killed 
by natives during Leichardt’s expedition, to which he had attached 
himself. 
During Gould’s absence his business affairs had been attended to 
by his faithful secretary, Mr. E. C. Prince, a most amiable and con¬ 
scientious man, whom I knew personally when I first came to London, 
and from whom I heard many anecdotes of his patron’s early struggles. 
Mr. Prince entered Mr. Gould’s service shortly before the latter went to 
Australia; and he is especially thanked for his administration of the 
traveller’s affairs during his absence, in the “Introduction” to the 
£ Birds of Australia.’ At the time of leaving for his travels in the 
southern hemisphere, Gould had made seven thousand pounds by his 
publications, so I was told in after years by his secretary; and it 
shows the marvellous self-reliance of ihe man, to undertake the long 
journey to Australia (a much more arduous business fifty years ago 
than it is now) for the purpose of procuring specimens and sketches 
of the country, that his work, on his return to England, might be
