MADE ON THE COASTS OF EUROPE AND AMERICA IN JUNE 1835. 307 
Table X. The Greatest and Least Ranges of the Tide at the places of observation 
selected as above. 
In this Table I have inserted, for the foreign stations, the names of the directors of 
the observations, and of the observers ; also the latitudes and longitudes of the places 
when those have been given along with the observations. For the British stations, 
I have given the range from the observations of June 1834 as well as 1835 ; and the 
names of the Inspecting Commanders of the districts of the Coast Guard, under 
whose direction the observations were made in 1835. 
Table XI. Semimenstrual and Diurnal Inequalities of the Height of High Water 
at several places of observation. 
In this list, those places are taken at which the diurnal inequality is most distinct 
and regular. 
Plate XXIV. Map of the British Isles and coasts of the German Ocean, showing 
the cotidal lines (according to the correct establishment). 
Plate XXV. The same Map, showing the range of the high tides at each point of 
the shore (in yards). 
Plate XXVI. Map of the coasts of Europe, showing the cotidal lines according to 
the correct establishment. 
Plate XXVII. Diagram exhibiting examples of the curve of the heights of high 
water, affected by the diurnal inequality, which has different epochs at different 
places. 
The materials upon which the above Tables and Maps are founded are deposited in 
the Hydrograph er’s Office in the Admiralty ; and I will give a list of them, since they 
may be of use in future investigations on the subject. They are. 
The original Registers of the Coast Guard Observations in June 1834. 
The original Registers of the Coast Guard Observations in June 1835. 
The Registers of the Observations made in June 1835, transmitted to the Admiralty 
from North America, Portugal, Spain, France, Belgium, the Netherlands, Denmark, 
and Norway. 
Founded upon these there are Tables containing 
The Times of High Water arranged in order for each place ; 
The Lunitidal Intervals calculated from the Times ; 
The curves of Lunitidal Intervals for most of the places of observation, and for 
several groups of places, in order to obtain Tables I. to IX. by graphical interpolation; 
The Heights of High Water arranged in order for each place ; 
The Curves of High Water for most of the places of observation, in order to obtain 
Table XI. by graphical interpolation. 
The mean Lunitidal Intervals have also been calculated by addition for most of 
the places ; but as I have not used these, I have not given them.
