tant storm, and which may likewise often proceed from the direction sub- 

 sequently taken by the wind, for this latter noise propagates itself in 

 every direction, and chiefly in that of the wind ; whereas the " calling'* 

 is heard only from one direction, and usually contrary to the wind. 

 Besides, if this " calling" come from the north-eastern, or inmost shore, 

 of the bay, and the wind afterwards change to that quarter, it could not 

 possibly arise from a " ground sea" produced by a distant storm from 

 that direction. 



Hence it appears that the " calling" of the sea depends not on the 

 condition of the sea, but on that of the atmosphere. I am informed, too, 

 that previously to a change of weather, all distant sounds are heard 

 loudest in the direction which the wind subsequently takes. The fisher- 

 men of Portleven, who are very observant of all signs of atmospherical 

 changes, are particularly attentive to this. They also notice the motion 

 of the clouds, and observe whether these are moving or not in the direc- 

 tion of the vanes — one very singular and sure sign which they have, that 

 the wind will change in the course of the day to the south-west, is a 

 morning fog flowing from the Loo-pool into the bay towards that point. 

 These last indications may possibly assist in ascertaining the cause of the 

 ** calling of the sea." — Richard Edmonds, Esq. Eleventh Annual 

 Report of the Royal Polytechnic Society of Cornwall, p. 47. 



4. Fossil Physeter Whale. — In the collection of Mr Brown of Stan- 

 way, is a remarkable fossil, which Professor Owen proved to be the tooth 

 of a Cachalot, and, in the report of the British Association for 1842, 

 states to have been procured from the Diluvium of Essex. Mr Charles- 

 worth having examined the specimen in question, considers it a genuine 

 crag fossil from the same deposit with the cetacean remains described by 

 Professor Henslow at a previous meeting of the Association. 



5. A recently discovered Bed of Diamonds in Mexico. — According 

 to the report of an expert geologist, Von-Gerold, diamonds have been 

 discovered in the great Mexican mountain range, in the Sierra madre, 

 in the direction of Acapulco, (to the S.W. of the city of Mexico.) 

 Humboldt had conjectured that diamonds and platina occurred further to 

 the N.W. in the gold washery of Sonora. It is also said that immense 

 tracts of auriferous alluvium occur in Upper California, as also in New 

 Mexico. They are principally in the possession of wild tribes, a circum- 

 stance which will accelerate the intrusion of the North Americans, and 

 hasten the taking possession of them by strangers.* 



6. Structures and prohdble mode of formation of the older Mountain 

 Rocks. — Those naturalists who continue to believe in the existence of the 

 true stratified structure in primitive and many transition rocks — who 

 consider mineral veins as of after formation to the rocks in which they 

 are contained — who conceive inclined tabular rocks (the old stratified 

 rocks of authors) to have been upraised from an original horizontal posi- 

 tion — who maintain that the natural seams of rocks, sometimes bounding 

 OP enclosing masses many hundred yards or fathoms in extent, are me-
