Legacy Hall became ill early in 1915, but carried on his work until shortly before his death from chronic nephritis on 21 December 1915. He was given the honorary degree of D.Sc. by Melbourne University in 1908. Hall's work with Dr Pritchard on the tertiary fossiliferous strata of Victoria, and his own work on the graptolite rocks of Victoria gives him a permanent place in the history of Australian geology.
