Before this, however, Dr. Armstrong had left the Survey, and it was not until the end of the year 
1884, when Commander A. Carpenter, R. N., was appointed to the command of the ‘ Investigator,’ and 
Surgeon (now Major) G. M. J. Giles, I.M.S., to the post of Surgeon-Naturalist, that deep-sea dredging 
became a recognized, if subordinate, branch of the ship’s routine. 
Since 1885 the Zoological collections made by the ‘ Investigator’ have been steadily accumulating 
in the Indian Museum, where, in accordance with the recommendations of the Council of the Asiatic 
Society of Bengal, they have been deposited. 
It must not, however, be supposed that deep-sea dredging occupies a very large part of the 
attention of the officers of the Survey ; since, as a rule, it is only possible when the ship is proceeding 
to and returning from her systematic surveys of the shores and shallows. It is rarely indeed that as 
many as twenty deep-sea hauls are made in one year. 
From October 1888, when regular records began to be kept, up to the present time, 113 more or 
less successful hauls have been made in depths of over a hundred fathoms (100-1997 fms.) : of these 
41 have been under the superintendence of Captain A. R. 8S. Anderson, I.M.S., who has been Surgeon- 
Naturalist since 1893. 
As regards the ‘ Investigator’ herself, she is a paddle-steamer of 580 tons, and for afew facts as 
to her history and equipment I may refer to a paper in the Scientific Memoirs of the Medical 
Officers of the Army of India for 1898.
