cdkria ; 5 Merganser; 20 Anas; 4 Pelecanus. This account 

 Was accompanied wiih interesting observations on the di- 

 stinctions of several of the species, their changes of plumage 

 at different ages and times of the year, and their kind of 

 food 5 and specimens of some of the dubious species were 

 exhibited. 



Mr. Jameson, at the same meeting, read the following 

 mineralogical queries, and stated the reasons that induced 

 him to consider the objects pointed out by them as deserving 

 the particular attention of mineralogists.

 and what are their other geognostic relations ? 



3. Are the trap-veins that traverse the mining field at 

 Strontian, basalt, porphyry-slate, or green-stone ; or do ail 

 these different species of rock occur in that district? 



4. Does the quartz rock of Scuraben and Morven in 

 Caithness, and of Portsoy in Banffshire, occur in an uncon- 

 formable and overlying position, or does it belong to the 

 conformable primitive rocks, as clay-slate or mica-slate?
