TABLES ILLUSTRATIVE OF THE RISE AND FALL 



of the calany river during 184)3, 4, 5 9 & 6.^ 

 By John Capper, Esq. 

 (Bead 22d May 1847. J 



The Diagram which I now lay before the Society, is intended 

 to shew at one view, the rise and fall of the Calany Ganga> 

 and has been^ompiled from a Register kept at the Bridge of Boats 

 by the Sergeant in charge of the Establishment there, and which 

 Register is filled in daily, accompanied by notes relative to the 

 state of the weather. 



In drawing this up I had two objects in view ; to ascertain 

 the existence and extent of any Tidal influence on the river^, 

 and also to determine what connection existed between the 

 extreme heights of the river and the various phases, of 

 the moon, 



A careful analysis of the daily registrations has left me with- 

 out any satisfactory conclusions as to the actual influence of the 

 Tides upon the fluctuations in the height of the river. The 

 rise and fall occur with such extreme irregularity as to forbid 

 anything like a conclusion on this point, at the same time I 

 believe the Master Attendant of Colombo, Captain James Steu- 

 art, made a series of observations a few years back, which 

 prove the existence of Tides along our shores, and if I re- 

 member rightly the extreme rise at high water was about 

 %\ feet. 



Almost as unsatisfactory has been the result of the inquiry 

 as to the connection supposed to exist between the moon's age 

 and the change in the weather as experienced in the ©welling 

 of the stream of the Calany.
