Specimens of British Wild Flowers. 815 



my doing this ; but a few came under my notice. One general 

 observation, however, I make, that the species is modified 

 by the climatic and other conditions of the two countries 

 in Canada the same plant being usually sturdier than in 

 Britain. This is true, for instance, of Solidago virgo aurea 

 of the Silene inflata, called the Silene cucubalus in England, 

 of the Verbascum thapsus, of the Arctium lappa, and of the 

 Epilobium Angustifolium, among others that occur to me. 



I have made a catalogue of the collection, but I wish to 

 copy it for the duplicate specimens which I have retained 

 for my private Herbarium. As soon as I have a little leisure 

 to do this piece of clerical work, I shall have great pleasure 

 in putting the catalogue in the hands of the curator of the 

 museum. 



ON THE GrEOLOGY OF QUEBEC ClTY, CANADA. 



By Henry M. Ami, M.A., F.G.S. 

 (Of the Geological Survey of Canada.) 



The researches of Sir William Logan, Mr. Billings, Dr. 

 S terry Hunt, Dr. Selwyn, Sir William Dawson, Prof. James 

 Hall, Prof. Emmons, Prof. Walcott, Prof. Marcou, Dr. Ells, 

 Prof. Lapworth, and many others on the geology of Quebec 

 and its environs have made that region classic ground to the 

 student of North American Geology. The famous Quebec 

 group controversy, as well as its closely related friend, the 

 Taconic question in geology, and the Lorraine-Hudson 

 .River problem, are all involved in the geologic history of 

 Quebec. Much diversity of opinion has existed as to the 

 exact geological position of some of the terranes at and 

 about Quebec City, as also along the whole line of the great 

 Appalachian or St. Lawronce-Champlain. Nor is this 

 at all astonishing, seeing that profound dislocations 

 exist, intricate foldings of strata occur, and several terranes 

 are met within very narrow belts, faulted and folded to- 

 gether in anything but a simple manner, which requires
