tion of the true level of the mean high water or of the land at the 

 places mentioned. The remaining levels are from the survey for 

 the Eastern Bengal Railway, and may be depended upon within 

 fractional quantities, both as regards accuracy and levels of water. 



The whole is based on the assumption that the highest level of 

 the floods represents the highest level of the land, and that this 

 datum at Calcutta is 27 feet above the Howrah Dock Sill.

This last would make the level of high water and of the land at 

 Goahuttee about 100 feet, at a distance of 350 feet from the sea, 

 which accords very tolerably with that of 70 feet given by Schla- 

 gintweit for the low-water-level above mean sea-level.
