WORK OF THE ‘ INVESTIGATOR.’

Sanitary Department, He has given to us a vivid account 
of his experiences during his tenure of office in the Marine 
Survey in Naturalist in Indian Seas” : his description of 
his first view of a growing coral reef, and the subsequent 
reception of his catch on board the ship, is most graphic. 
But the fates decided that he was not to be permitted to 
give up zoological work, and in 1893 he again became 
connected with the Indian Museum in the capacity of Super- 
intendent. 
In succession to Alcock, Surgeon-Captain A. R. S. 
Anderson was appointed in 1893 to fill the vacancy on the 
Survey staff, a post that he held till the year 1899, with the 
exception of the survey season 1895-96, during which Sur¬ 
geon-Captain Wemyss Grant officiated for him. During his 
first season Anderson was able to carry out a number of 
trawls in the seas to the south of India, for the ship was at 
that time surveying the Palk Straits and early in the season 
also paid a visit to the Laccadives, where the opportunity 
was taken to do some collecting on shore. At the commence¬ 
ment of season 1894-95, the investigator’ visited the 
mouth of the Indus River, and it is interesting to note that 
a trawl was carried out in that part known as the ^indus 
Swatch” at a depth of 170-210 fathoms, the result, however, 
was, from a collector’s point of view, very meagre and did 
not approach in interest that obtained in the Gangetic 
Swatch in 1884. Later in the same season and during the 
following year the area under survey was again the region 
of the Palk Straits, so that Anderson was thus enabled to 
increase his collections from this locality: one trawl in parti¬ 
cular, at station 197, proved to be one of the richest for 
several years and yielded many new species of animals. In 
1895-96, as already mentioned, Surgeon-Captain Wemyss Grant 
officiated for Anderson, the area under survey being again 
the region round the Indus delta. The next year Anderson 
again rejoined the ship and the scene of operations was laid 
in that naturalists’ paradise, the Andaman Islands; not only 
did he carry on shore-collecting in the Andamans themselves, 
but as the ‘ Investigator ’ was unable for the time to devote 
any attention to trawling, he accepted an invitation to visit
