In situation* of this kkid, what means of preservation are 

 necessary must be employed at first ; as it seems scarcely 

 possible to renew them on fixed timber with any chance of 

 benefit.

 Werner tan Natural History Society, 



x\t tlie last meeting' of the Wernerian Natural History 

 Society, Profeesor Jameson read an account of a method 

 of constructing and colouring mineralogical maps. We 

 cannot give a satisfactory account of this paper without 

 drawings; we shall therefore only observe, that maps exe- 

 cuted according to this plan show distinctly the figure of 

 tiie cliffs, terraces, mountain ranges and mountain gvoupes : 

 and the colouring affords a true and harmonious representa- 

 tion of the alternation, extent, and relative position of the 

 different rocks that appear at the surface. Professor Jame- 

 son at the same time laid bei'ore the society a series of mi- 

 neralogical queries, which lie had drawn up v/ith the view of 

 directing the attention of mineralogists to the particular ob- 

 jects pointed out by them. 



We have permission to communicate these queries to the 

 public.

1. Does the granite of Cornwall belong to the oldest or

 that county ? 



2. Is the schorl rock of Cornwall disposed in an uncon- 

 formable and overlying position in regard to the older pri- 

 mitive rocks ; if this be its position, on what rock or rocks 

 does it vest, and what are its other geognostic relations ? 



3. Does the serpentine of Cornwall belong to the first or 

 second serpentine formation, and what are the imbedded and 

 venigenous fossils it contains? 



4. What are t!ie characters of the different metallifarous
