0 inches * above summer level. Heights were also noted on 
the railings at the foot of the steps on the upper side of Lendal 
Bridge, by the Waterworks offices. These, on the 26th, were 
found to give a fraction of an inch over 15ft. lOin. above the 
same gauge-level. This mark was 22 inches higher than the 
mark I recorded at the same spot in the flood of March 10th, 
1881 ; and at the Ouse Bridge gauge the height is reported 
to have been 15ft. 8in., with which my observations agreed. 
These slight differences may be merely due to errors, but 
they are very probably real, and mark the fall of level in going 
down stream during high flood. Since writing thus far I have 
obtained from Mr. Creer, our efficient City Surveyor, a valuable 
series of levels, taken from ordnance datum. We thus get the 
following table, based upon the fact that the “summer level” 
of the Ouse bridge gauge is 1675 ft. 
or 16 ft.

* Corrected for error of Ouse Bridge gauge, set 2 inches below ordnance datum 
for summer level, 16ft. 9in. 
+ Since this was in proof, Mr. Creer has taken independent levels, which agree 
within less than half an inch of my own results.
