neither instance was there the slightest derangement of the fossils visible. 

 Having illustrated the details we have reported, Mr Cunningham con- 

 cluded by advising geologists to pay greater attention than was generally 

 done to the mineralogy of rocks. The paper was accompanied by many 

 large sections descriptive of the details which were entered into. 



There were laid before the meeting tables of several 3'ears' meteoro- 

 logical observations made at Fort Vancouver, and for a whole year among 

 the Sandwich Islands, by the late Dr Meredith Gairdner. 



December 21. — Professor Jameson, P., in the Chair. The Secretary read 

 a communication on Professor Ehrenberg's discoveries respecting the Mi- 

 croscopic Animals which form the chief component parts of Chalk and 

 some of its associated rocks. Dr Greville read a letter from Mr Shuttle- 

 worth of Berne, stating, that some of the organisms supposed by Pro- 

 fessor Ehrenberg to be of an animal nature had more probably a vege- 

 table origin. The President exhibited a large specimen of green fluor- 

 spar which had been observed in a new locality' in Banflshire, (the " Three 

 Burns," between Gaulrig and Little Fergie, River Aven), by Mr Hay 

 Cunningham. Mr Stevenson mentioned, that, up to the 1st December, 

 no snow lay upon the mountains of the Outer Hebrides, which, in ordi- 

 nary seasons, are clothed with snow in the end of October or beginning of 

 November ; but that wild swans were abundant in the lochs, indicating 

 a severe winter in Iceland and Faroe.

 History, and more especially the Geology, of the portion of the Himma-

 Professor Jameson read an analysis of a Clay eaten b}' the Negroes in the 

 West Indies. Dr Neill, the Secretarj', then read Mr Thomas Eraser's 

 account of the Geology of the western part of Morvcn. Professor Ja- 

 meson took this occasion to state his views in regard to the so-called 

 Btratificd stcucturc of primitive rocks, which he, in conformity with his
