As this boring commenced in the Lower Lias, near the top of that deposit, which is at least 800 feet thick, the saline water must either be derived from the Lower Lias, or must have flowed up along the plane of some fault or joint from the Keuper Marls below.

In the Cleethorpes boring the top of the chalk was very rotten. and had to be tubed out down to 120 feet from the surface, or 21 feet from the top of the chalk. The yield from this boring is only about 180,000 to 192,000 gallons per day, and it is evident that the water is not entirely tubed out from the upper part of the Chalk, from the fact that, when this quantity is pumped, the water-level being 24 feet from the surface, the neighbouring wells and boreholes all lose their supply of water, none of which do more than penetrate the top bed of the Chalk.

At Grimsby Docks there is a well in the Chalk 300 feet deep; the water is clear and palatable. Analysed by the Rivers Pollution Commission, was found to have a hardness of 22'1, of which 76 was permanent; chlorine was 5'00, in parts per 100,000.

NOTES ON SOME NEW OR BUT LITTLE KNOWN EOCENE POLYZOA FROM LOCALITIES. BY GEORGE ROBERT VINE.

Some time after my first paper "Notes on British Eocene Polyzoa,"* had been placed in the hands of the printer, I received from Mr. Alfred Bell another small packet of Eocene material for description. And quite recently (Feb., 1891), a few additions have been made by the same gentleman to the original stock, differing but little, however, from the first batch; so I think I shall now be able to describe, or incidentally refer to, all the Polyzoa known to me, from the several British Eocene horizons. The Polyzoan fauna that will be referred to further on, is altogether unlike the species already described, and so far as I am aware most of the forms are new to British rocks, some of the species at least being more closely allied to the Cretaceous Polyzoa of France, as described and illustrated by d'Orbigny, than to ordinary Tertiary forms, British or Continental. 'The locality whence most of the forms are derived, Fareham, Hants, is also new to me, consequently I asked Mr. Bell to draw up for the introductory part of this paper a brief synopsis of "Hants and its Fauna," which I give below in his own words:

In widening the railway near this place (Fareham) a short time back, a deposit, containing a peculiar assemblage of mollusca, was opened up, including a large number of Brachiopods, Terebratula bisinuata, Lam., which at the time of publication of Dr. Davidson's Monograph of Fossil Brachiopoda, 1852, only two examples were known, collected from the Bracklesham beds and the Hampshire cliffs. I have since obtained other fragments from the Bracklesham sands.

The Fareham Brachiopods are very local, nearly all double, much crushed and distorted, and appear to have been destroyed by a sudden influx of mud or other matter. Polyzoa not being, so far as I can ascertain, associated with them as they are with some of the other shells.
