56 REPORT—1846, 
The quantity of water which the shaft will contain below the present water level 
is as follows :— 
120 feet at 13 feet 0 inches diameter...... 15,927 cubic feet. 
50 feet at 11 feet 6 inches diameter ...... 5193 cubic feet. 
50 feet at 10 feet 0 inches diameter ...... 3927 cubic feet. 
50 feet at 8 feet 6 inches diameter...... 2837 cubic feet. 
250 feet at 7 feet 0 inches diameter ...... 9621 cubic feet. 
520 Totalii.t. 37,505 
In conclusion, the question we have now to settle is, whether it is better to be 
content with the well in its present condition, or continue the boring, for the chance 
of obtaining a larger and less expensive ‘supply from the greensand formation. 
The example of our neighbours on the other side of the channel certainly affords us 
much encouragement to proceed with the work; but we have not sufficient confi- 
dence in our own opinions to venture on such a step without the advice of those 
whose scientific knowledge and better judgement we are most anxious to obtain. 
On the Applicability of M. Fauvelle’s Mode of Boring Artesian Wells to the 
Well at Southampton, and to other Wells, and to Sinkings for Coal, Salt and 
other Mineral Beds. By the Very Rev. W. Bucxianpn, D.D., Dean of 
Westminster, F.R.S. 
Dr. Buckland recommended that the boring on Southampton Common should be 
continued by M. Fauvelle’s method. He stated that there was probability of ob- 
taining a more abundant supply of water by going deeper into the chalk; but that 
it would rise no higher in the shaft than the level of the nearest outlet at Otter- 
bourne, where the water of the chalk makes its escape. From the observations of 
Mr. Clutterbuck, it appeared that the water stands gradually higher in the wells 
on the line of railroad between Southampton and Basingstoke, at the rate of about 
a foot higher for every mile. 
The water in the greensand beds next below the chalk was derived from rain that 
falls in districts where these sandy strata form the surface of the country; the nearest 
of these surfaces being in the axis of the Isle of Wight, and in the Vale of Peters- 
field, and the Vale of Pusey. From these three districts (unless where cut off by a 
fault) there was probably a subterraneous passage for water through the interstices 
of the upper greensand beds, beneath the whole of the Hampshire basin, this water 
being upheld by subjacent impervious beds of gaulé clay. The height to which this 
water could rise through a hole bored in the chalk, would depend on the levels at 
which the springs from the greensand nearest to Southampton find their issue. 
These levels should be ascertained, especially near Petersfield. 
On the occurrence of Cypris in a part of the Tertiary Freshwater Strata of 
the Isle of Wight. By Josrru Prestwicu, Jun., F.G.S. , 
Although aspecies of this small crustacean abounds in the tertiary lacustrine de- 
posits of Auvergne, and is not uncommon in the upper beds of the Paris basin, whilst 
lower in its strata M. D’Archiac quotes a new species in the ‘ Gres de Beauchamp,’ 
and the Cypris punctata from the plastic clay or lignite group, yet it is extremely rare 
in the English tertiary series. In the London basin I believe that no freshwater form 
of it has been found ; one species of the marine form, the Cytherina, has been met 
with at Highgate. In the Hampshire basin, mention is made by Mr. Lyell, in the 
third volume of the Transactions of the Geological Society, of the rare occurrence of 
an undescribed, and, I think, a tuberculated species in the freshwater strata at Hordwell 
Cliff. In the fine sections of Alum Bay, Headon Hill, and White Cliff Bay, in the Isle 
of Wight, amongst the other abundant organic remains, I never detected any fossil 
Cyprides. Having lately had an opportunity of making a hasty visit to Hampstead 
Cliff, about 14 mile east of Yarmouth, I there found a species of Cypris in considerable 
abundance. The cliff being composed chiefly of beds of clay and marl, forms a sur- 
face easily acted on by the weather, and presents innumerable slips and prolonged
