314 Mr. Horner on the Mineralogy of the Malvern Hills, 



§ 70. St. Amis 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. A 

 gallon of the water yielded 7,395 gi^s. 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, with- 

 out 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.
