base of a blufFhill called Humphrey Head, the extreme point of a 

 range of calcareous hills forming the eastern boundary of the Vale 

 of Cartmell. The water is emitted through a small lead tube about 

 an inch in diameter, surrounded and enclosed by rough masonry, and 

 ■which delivers a gallon of water in about 1' 47". The specific gra- 

 vity of the water is 1.006, and the relative proportions of its con- 

 tents appear, from various experiments, to be as follows, in a wine 

 pint of the water: — 



Carbonic acid gas One cubic inch. 



Carbonate of magnesia 0.266 



Sulphate of soda 3.872 



lime ....... 1.500 



magnesia 3.000 



Muriate of soda 19.782 



magnesia 9.000 



Peroxide of iron 1.750 



Insoluble in muriatic acid, principally ) ^ ^^^ 

 silica \ 



42.170 grains. 



7. Eruftion of Sulphuretted Hydrogen. — A singular phenomenon 

 has occurred on the river Calfkiller, near the salt-works, about 

 three miles from Sparta (Turna), in the United States of America. 

 A column of fire, nearly forty feet high, rose from the waters in the 

 middle of the river; it extended over a space of fifty verges, and 

 illuminated objects at a considerable distance, the tints thrown 

 over them were red, green, yellow, blue, §-c. It seems to have 

 been occasioned by a sudden burst of sulphuretted hydrogen 

 which was inflamed by the approach of a lighted torch. The 

 liberation of the gas is attributed by some to the operations of the 

 workmen who Avere looking after salt, but the explanation seems 

 doubtful. — Revue Encyclopedique. 



8. Ammonite containing Shells. — iSI. L. A. D'Hombres-Firmas, 

 describes certain ammonites, found between Vezenobres and le 

 Garden, about two leagues from Alais, on a hill about 130 metres 

 hio-h, of a calcareous rock, white externally, bluish internally. 

 The ammonites occur whole and in fragments, many of the frag- 

 ments of a large size ; one, and only one, which was found by the 

 author himself several years since, is remarkable for containing 

 shells. It is fractured, but has been about 1 1.8 inches in diameter. 

 In most things it resembles other ammonites : but about fifteen 

 other shells, imbedded in its substance, appear at its surface, and, 

 probably, there are others within ; some present the edges, others, 

 portions of convex surfaces, and others apertures ; they are 

 bivalves, and, probably, terebratula; they are nacreous, and from 

 three-quarters of an inch to one inch in size. — Bib. Univ.
