I'.rt'ore this, however, Dr. Armstrong had left the Survey, and it was not until the end of the year 

 1SS|. when Commander A. Carpenter, E. N., was appointed to the command of the ' Investigator,' ami 

 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 

 71 have been under the superintendence of Captain A. B. S. 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 a few 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.
