Mr Whiteaves remarked that of the plants found at St 

 Jerome, four were rare species and had not yet been found on 

 the Ishind of Montreal. 



The chairman made some remarks in reference to the Paris 

 Exhibition, and the Canadian Exhibit which excited wonder and 

 surprise in the numerous visitors from all countries. Special 

 mention was made of the gold octahedron, the huge mass of 

 plumbago, the pyramid and tunnel of coal, and the representation 

 of Canada's lumber wealth. The latter was a timber frame 

 supporting a section of an immense British Columbian pine, pla- 

 carded " This tree was at least 150 years old when Columbus 

 discovered America." 



Views of the Canadian Exhibit and pamphlets showing Can- 

 ada's natural productions were passed round during the evening 

 and carefully examined. 



The fourth meeting was held on the evening of Monday, Feb. 

 24th. Principal Dawson occupied the chair. There was a large 

 attendance of members and friends. The evening was spent in 

 hearing a paper from A. R. C. Selwyn, Esq., F.R.S., director of 

 the Geological Survey, on "The Stratigraphy of the Quebec 

 Group and the older Crystalline Rocks of Canada." with a dis- 

 cussion on the same. Mr. Selwyn's paper, which we publish in 

 this issue, was illustrated by maps, sections and specimens. A 

 hearty vote of thanks was tendered to him for his able and ex- 

 haustive paper.
