The first patient etherised by David John Thomas was James Egan, an Irish bounty immigrant who lived on a pastoral lease about 120 km from Melbourne. Egan had injured his left hand and forearm in a shooting accident. It would take Egan five or six days to reach Melbourne where he had his forearm amputated on 2 August 1847. Egan had fainted frequently in the cart on the way to Melbourne and was fortunate to survive the etherisation and surgery. In September 1847, Thomas presented a paper on etherisation at a monthly meeting of the Port Phillip Medical Association-this is the earliest known presentation of a paper on etherisation in the Australian colonies. The original manuscript of Dr Thomas is now held by the Medical History Museum at the University of Melbourne.
