THE INDIAN MUSEUM: 1814—1914. 
next few years much of her time was spent on the coast 
of Orissa and Madras, and in many localities, when trawling, 
for any reason, could not be undertaken, Alcock availed him¬ 
self of the opportunities that occurred to visit the various 
islands and shores and make collections of the littoral fauna. 
As a result, during the few years he was in office a very fairly 
representative collection of the fauna of Indian waters was 
made. As was but natural during the first years of such a 
survey, it was the larger and more obvious animals that 
attracted attention, and as the collections, year by year, were 
sorted and worked out in the Indian Museum, a series of 
papers, dealing for the most part with the fish and Crus¬ 
tacea, were published either in the Annals and Magazine of 
Natural History or in the Journal of the Asiatic Society of 
Bengal. 
In 1890 the Government of India sanctioned the ap-* 
pointment of an artist to the Marine Survey, for the work of 
drawing the numerous zoological treasures that were being 
brought to light; at the same time they undertook to pay for 
the production and publication of twelve plates annually. For 
many years the plates were published separately under the 
title of ‘ ‘ Illustrations of the Zoology of the Royal Indian 
Marine Surveying Steamer ‘ Investigator,’ ” but latterly their 
publication as a separate issue has been discontinued and they 
are now included in the Memoirs of the Indian Museum. 
The first artist to be appointed to the post was Babu A. C. 
Chowdhary, and in 1892 he was succeeded by Babu S. C. 
Mondul, who still holds the appointment. 
During the survey season 1890-91 the area under 
investigation was part of the Andaman Sea: during the 
voyage out from Colombo to Port Blair two noteworthy 
trawls were made; the first of these was taken at station 
110: 9° 34' N: 85° 43' 15" E in 1997 fathoms; this was then 
and up to the present date still is the deepest haul ever made 
by the ‘ Investigator ’ ; the second was in shallower water, 
in 561 fathoms at station 112: 13° 47' 30" N: 92° 36' E. It 
is noteworthy because it demonstrated for the first time that 
many deep-sea Crustacea are phosphorescent. In 1892 Alcock 
retired from the post to take up an appointment in the
