The most proper observations for determining the rate and course of the Tide 
wave are those of the Time of High water on the same day at different points (not 
too near nor too remote) on a continued line of coast or sea. 
This may often be done by a person residing in any country by making enqui- 
ries of persons conversant with the coasts, or by directing corresponding observa- 
tions to be made at different places for a few days only. 
If the places differ much in longitude, this ought to be noted, that allowance may 
be made for the difference of the absolute time of noon. 
If there be any uncertainty as to the rate and course of travelling of the tide be- 
tween two places, the doubt may best be removed by obtaining observations at some 
intermediate point or points. 
It is necessary to distinguish the Time of High water at the mouth of a deep bay 
or sound, from the time of High water further in. The former is to be taken in 
all such comparisons as are here spoken of. 
Large islands and long promontories much disturb the regular progress of the 
Tide wave. 
Comparative Observations of the Height at different places in the same seas, es- 
pecially if combined with those of the Times, may also be of great value. 
All communications concerning any observations of the above kinds made or to 
be made in any part of the world will be thankfully received. They may be ad- 
dressed to the care of the Sec. Asiatic Society, or direct to 
The Rev. W. WHEwWELL, Trinity College, Cambridge ; 
or, at the Royal Society, London ; 
or the Astronomical Society, London.”’ 
The President read a letter handed to him by Dr. Strong, addressed to 
Major Benson, Mil. Sec. to the Right Honorable the Governor General, de- 
scribing the progress and present condition of the borings in Fort William, 
with the opinion of Sergeant Reid upon the causes of the repeated failures ; 
and suggesting that the Government should continue the experiment upon its 
relinquishment by the Society: Major Benson explained that the present 
reference to the Society had for its object to obtain their opinion as a body 
upon four essential points before recommencing operations ;—the probability 
of ultimately finding a spring ;—the expediency of making the further at- 
tempt ;—the mode of avoiding such accidents as have hitherto impeded the 
auger :—and the estimated expense. 
After some discussion, the following members were nominated a Committee 
to draw up a report with advertence to these points. Dr. Mill, V. P. Dr. 
Wallich, Dr. Langstaff, Mr. Seppings, Captain Forbes, and Dr. Casanova. 
. Antiquities. 
Read extracts of a letter from Lieut. A. Burnes, presenting to the Society 
eleven of the coins collected by himself in his recent visit to Manikyala. — 
Two or three of these coins are in excellent preservation, with very decypherable 
Greek inscriptions, and are thus proved to be of Bactrian fabrication :—they bear 
the several devices of the equestrian figure ;—the man in the tunic 3—the elephant ;— 
&c. and agree in other respects with the coins described in Mr. Wilson’s paper
