We can make out, approximately, in liow far the computed levels 

 and the velocities satisfy this condition by availing ourselves of the 

 levels and velocities computed for each half hour and for the different 

 distances from the Pacific. We thus find as follows : 



A. For the differences in the discharge at 9 and 27 K.M. 



distance from the Pacific. 



B. For the change of the mass of /rater contained in part 9 — 27, 



Comparing the last columns of the tables A and B we get the 

 following differences for part 9 — 27 : 



from 4 1 /, to 5 hours + 195000 M\ or on an average per sec. -f- 108 M\ 

 >> 5 ,,5 / s ,, -+ 55000 ,, ,, ,, ,, ,, ,, ,, + ox ,, 



)> 5 / a ,, o ,, — oJOOO ,, ,, ,, ,, ,, ,, ,, 22 ,, 



It appears from this comparison, that by the computed velocities, 

 taken in conjunction with the computed levels, the condition of 

 continuity is not fully satisfied. 



Therefore, assuming the levels to be correct, the velocities need 

 some correction.
