The last sample gave 12^5 grains per gallon of carbonate of magnesia. 



At Rawcliffe Station Well samples taken September 16, 1875, showed the same 

 chalybeate taste and smell which obtains at Goole, but the quantity of ammonia is 

 less, thus :

Tlie hardness is also less, the total being 12^5, and permanent only io. The total 

 solids were only 30 grains per gallon, but the chlorine is 2^3. 



At Rawcliffe Hall Well, 250 feet in the New Red Sandstone, the temperature of 

 the water is 51° ; it has no taste or smell, and only contains 27 grains of solids to the 

 gallon. 



At Selby Waterworks a sample of water taken July 27, 1874, yielded the fol-

Tliese results establish the fact that on approach to the outcrop of the New Red 

 Sandstone there is direct increase of purity, both as regards ammonia, total solid 

 impurity, and amount of hardness, and they agree with the results of Dr. Letheby, 

 at Heck, taken a month later in the .same year.

Very little water was struck till the borer reached the Lower Green- 

 sand, when it came up with great force, 7 feet above surface of ground. 

 The position is very near the centre of the London Tertiary Basin, and 

 the level about 230 feet above O.D., but of this I am not quite certain.
