﻿■230 Canadian Record of Science. 



If this be the African species, it has probably been 

 l»rought here by some African merchantman and wittingly 

 or accidentally dropped overboard. There is no record of 

 an animal dying in this vicinity. The absence of the 

 tusks, the only part of any value, as well as the absence 

 of the other bones, points to its being an importation. 

 If, on the other hand, it should prove to be a new A^ariety 

 of species, it would certainly be of great interest, as 

 no Hippopotamus remains have ever been discovered on 

 this continent heretofore, and further dredging operations 

 in this vicinity will be awaited with interest in view 

 of the possibility of more extended discoveries. 



The Anorthosites of the Rainy Lake Region.^ 



By Prof. A. P. Coleman, School of Practical Science, Toronto. 



A number of eruptive masses rising through the Kee- 

 watin (Huronian) schists and schist conglomerates of the 

 Eainy Lake region in western Ontario were mapped and 

 described by Professor A. C. Lawson in 1887, the most 

 interesting group of eruptives occurring along the southern 

 shore of Seine Bay and between Bad Vermilion and Shoal 

 Lakes, just to the east.^ Here very basic and very acid 

 rocks are found associated. The acid members of the 

 group, quartzose granites containing much plagioclase, 

 have been studied somewhat carefully from the fact that 

 they contain important gold-bearing veins, but the barren 

 nnorthosites have l)een neglected. The soda granites, 

 which often weather into the greenish sericite variety, 

 protogine, and liave l)een slieared and metamorphosed into 

 sericitic schists near the quartz veins, have been described
