All except four of the above have been photo-zincographed for 

 local use, and all except that of the Meghna flats, which was purely 

 astronomical, were based on data of the Great Trigonometrical 

 Survey. Sailing directions, tidal and other data were also 

 compiled. 



Tor the next season the sanctioned programme comprised a 

 survey of the western coast of the Andaman islands, and of the 

 Gam' am coast between Santapilly and Hurrichpoor in latitude 20° N., 

 but later on the Madras Government requested that that of the 

 Ganjam coast might be postponed another year. 



A line of deep-sea soundings was carried from Porbandar to the 

 Laccadive islands, one result of which was to indicate that the 

 Laccadive submarine peaks spring from an ocean floor about 

 1,100 fathoms, or one and a quarter land miles deep, and are 

 themselves about the same height as the Western Ghats in those 

 latitudes. 



A curious discovery was made at Chitlac island, tending to prove 

 the existence of a southerly current on the west coast of India. 

 A large wooden tank had floated ashore over the reef in September 

 1885 with a human skull inside, and from enquiry this appeared to be 

 part of the wreckage of the British Indian wooden barque " Jabree," 

 of 695 tons, with a crew of 60 men and 40 passengers, an account 

 of the loss of which is given in the Wreck Begister for 1885.
