§70. St. Ann's Well water afforded no other gaseous contents than atmospheric air. Its solid ingredients are precisely of the same nature as those of the Holy Well, but in much less quantity. At gallon of the water yielded 7,395 grs. which consisted of:
| Carbonate of soda | 3, | 55 |
| Carbonate of lime | 0 | ,352 |
| Carbonate of magnesia | 0 | ,26 |
| Carbonate of iron | 0 | ,328 |
| Sulphate of soda | 1 | ,48 |
| Muriate of soda | 0 | ,955 |
| Residuum | 0 | ,47 |

| 7 | ,395 | |
§ 71. The chalybeate spring, according to the analysis of Dr. Wall, contains about 6 grains of solid ingredients in a gallon.
§ 72. I was informed by Mr. Wallett, Surgeon at Great Malvern, that a spring on the western side of the Herefordshire Beacon, known by the name of Walm's Well, has been long used, by the country people in the neighbourhood, as an outward application in cutaneous diseases. The water flows in a pretty copious stream, and at the place where it issues from the hill, is collected by an embankment, so as to form a large bath. Through the kind assistance of Dr. Marcet, I have made the following examination of this water, with the view of ascertaining merely the nature of its contents, without any regard to proportions, as the quantity I brought away was much too small for that purpose.
§ 73. The water, as it issues from the hill, is perfectly transparent, and remains so after exposure to the air. It produced no change on tincture of red cabbage.
Its specific gravity is 1000,10.
