[1] Henry was educated at University College School, London, and studied natural science and philosophy in the German Empire.
Papers on "The Climate of Mackay" and "On the Roots of the Sugar Cane" appeared in the Journal and Proceedings of the Royal Society of New South Wales in 1881 and 1883.
In 1896 Roth brought out another important book, The Natives of Sarawak and British North Borneo (published by Truslove and Hanson), largely based on the manuscript of Hugh Brooke Low.
Roth published Great Benin; Its Customs, Art and Horrors (1903), and The Yorkshire Coiners, 1767-1783 (1906), and Notes on Old and Prehistoric Halifax (1906).
[1] Roth was a modest man, his work in anthropology was very largely based on the fieldwork of other men, but he had a talent for collating information and records, and his volumes on the Tasmanian aborigines and the natives of Sarawak and North Borneo were standard books.
