have been ascribed are various. Heat, water holding different 

 substances in solution, gases, atmospheric agencies acting sepa- 

 rately or combined, have all played an important part in effecting 

 these changes. The rocks thus modified have been called meta- 

 morphic, altered or hypogenous rocks, without very marked refe- 

 rence to the classes from which thev have resulted. In the 

 following pages the name altered will be applied only to those 

 original rocks, and the term metamorphic only to those derived 

 rocks which have experienced, in situ, such changes as those here 

 indicated. It is not, however, proposed in the present paper to 

 discuss the relations of derived and metamorphic rocks, but, in 

 endeavouring to classify those of the original class, the altered 

 rocks sometimes resulting from them will be noticed.

THE PLANTS OF THE WEST COAST OF NEW- 



FOUNDLAND. 



By John Bell, M.A., M.D. 



The account of the plants of the west coast of Newfoundland, 

 in a recent number of this journal, ended with my visit to St. 

 George's Bay. 



As we sailed south, from that locality to the harbour behind 

 Cod Roy Island, I observed that the forests had in some places 

 been burned by the devastating fires, which are so often carelessly 

 originated in these parts, and that grass had sprung up in the 

 areas thus cleared, on which large herds of cattle were pasturing. 

 These cattle belong to the people of the island-harbour village, 

 which is composed of about thirty or forty families, whose school- 

 master visited us on our arrival. Large patches of snow still lay 

 glistening in the sun on the tops of this somewhat elevated range 

 of hills. 



On the following morning, July 6th, we started on an expedi- 

 tion up the Great Cod Roy River, which, like many of the 

 smaller rivers entering the Gulf of St. Lawrence, has its stream 

 level for a few miles inland, until it reaches the mountain 

 region, when it becomes more rapid and less navigable. It 

 resembles them, too, in the manner of its debouche. On nearing 

 the place where the river seemed to empty, we could at first see
