He received his early education at Dedham grammar school and in 1817 entered Jesus college, Cambridge; he was ordained, and became curate of Ramsholt, Suffolk. In 1839, after a severe illness, he left England for New South Wales, mainly with the object of benefiting by the sea voyage. He remained there, ac cepted a clerical charge, and came to be regarded as the "Father of Australian Geology." In 1841 he discovered gold, being the first explorer who had obtained it in situ in the country, finding it both in the detrital deposits and in the quartzites of the Blue mountains, and he then declared his belief in its abundance. In 1849 he made the first actual discovery of tin in Australia and in 1859 he made known the occurrence of the diamond. He was also the first to indicate the presence of Silurian rocks, and to determine the age of the coal-bearing rocks in New South Wales. In 1869 he announced the discovery of remains of Dinornis in Queensland. He was a trustee of the Australian museum at Syd ney and an active member of the Royal Society of New South Wales. In 186o he published Researches in the Southern Gold fields of New South Wales. He was elected F.R.S. in 1876, and in the following year was awarded the Murchison medal by the Geological Society of London. He died near Sydney on June 17, 1878.
