5. — Extract from a Letter addressed hy Dr. Daubeny to the Curator, on a 

 Saline Spring near Oxford. [Read June 10, 1835.] 



'' Dr. Buckland having announced to the Society (April 29, 1837.) the 

 existence of the salt spring- lately discovered near Oxford, an analysis of the 

 water may perhaps interest the Society, as it contained, when I made my ex- 

 periments, more sulphuric salts than any other spring in this country, and like- 

 wise a certain proportion of iodine. The saline contents in a pint were as 

 follows : — 



Chloride of sodium 70-82 



calcium ...... 7-25 



magnesium ..... 2-40 



Sulphate of soda ...... 52-40 



132-87 

 Also a proportion of hydriodic acid, yielding of iodine, in the pint, about 

 ^-V^ of a grain. The date of this examination was March 26th (1837), at 

 which time the borings had reached to 280 feet beio-«v the surface. Some 

 days later the water was not so strongly charged with sulphuric salts, though 

 the quantity was considerable." 



6. — Notice of a Letter addressed to Capt. Belcher, R.N., F.G.S., by H. Cuming, 

 Esq., dated March 5th, 1835, on the Earthquake in Chili, November \9th, 

 1822. [Read December 2nd, 1835.] 



The writer arrived at Valparaiso in January 1822, and resided there con- 

 stantly until 1827, and from the latter period, with occasional absences, till 

 May 1831. At the time of the earthquake, he lived in the Plaza Mayor, 

 near the landing place at the arsenal, and his house was destroyed by the first 

 shocks. He did not go to the beach during the night, but was informed that 

 the sea had retired a considerable distance, and had immediately returned with 

 great force. On the morning of the 20th he noticed the effects, but found 

 nothing more than a high tide. At the time of the convulsion it was dead 

 low water. He never heard of the rocks having been heaved up, or of the 

 permanent retirement of the sea, until the publication of Mrs. Graham's work
