the results of original investigation in most branches of 
Zoology and in Ethnology in its morphological and geo¬ 
logical aspects. His most numerous and most important 
contributions however were upon Insects—especially the 
Mantidae and Phasmidae—and upon the general subject 
of the Crustacea, which early attracted him. In 1873 he 
became Natural History Secretary, and during the greater 
part of the next sixteen years, though not continuously, he 
edited Part II of the Society’s Journal with conspicuous 
ability and success. In 1887 he was elected a Vice-President 
of the Society. Outside the limits of the Society his devotion 
to zoology was marked with no less distinguished ability and 
success, and in the course of his official career he became 
Deputy Superintendent of the Indian Museum, Professor of 
Zoology and Comparative Anatomy in the Medical College, 
and finally, on the retirement of Dr. Anderson in 1887, Super¬ 
intendent of the Museum. In 1888 he was made a Fellow of 
the University of Calcutta. 
His record of work, outside his official routine, and be¬ 
yond his connexion with the Society, is a long and varied one, 
and embraces explorations in the field, the publication of his 
scientific researches, and economic inquiries. Although his 
purely scientific work completely overshadows his economic 
work, yet his attitude to Economics in the proper place was 
not unfriendly. With the more aggressive Economists he had 
little sympathy, believing that science diligently and methodi¬ 
cally pursued for its own sake would be far more likely to 
yield incidental benefits to civilization than would science 
studied disconnectedly for the sake of the practical man alone. 
In the field he explored, in 1872, the marine fauna of the 
Andamans, and again, in 1873, that of the Nicobars, and in 
1888 he went for a time as Naturalist on board Her Majesty’s 
Indian Marine Survey Steamer ‘^Investigator.’ As a result 
of these field excursions he added largely to our knowledge of 
the life of the Bay of Bengal, and greatly enriched the collec¬ 
tions in the Indian Museum. He also, in the course of econo¬ 
mic inquiries into the tea-bug, and into the diseases of silk¬ 
worms, travelled and collected largely in Assam, Cachar and 
Lower Bengal.
