_ The greatest theoretical error, (A-C,) is only 0084 in. at 214, 
or ‘000297 of the entire height, and *127 of the daily range; 
least. error is at 54 and 154, 000004 of the height, or -00151 of 
the range; and the average error 0042 in., which is 000147 of 
the height, or -063 of the range. f 
__ The greatest difference between the observed height and the 
observed average, (A-B,) is at 20%, when it is 131 of the daily 
Tange; the least difference is ‘0068 of the range, at 1"; the 
average difference, ‘0639 of the range. 
_ The greatest difference between the observed averages and 
the theoretical height, (B-C,) is at low tide, or at 4h and 164, 
When the difference is less than ‘02 (say ‘0159) of the daily range} 
the least difference is at 2% from low tide, or at 24, 6, 14% 
18, when it is but little more than ‘001 (00113) of the range;
