Sir WiUmm Edmond Logan. 93 



Sir William Logan, 1 applied to them his terra, ' Laurentian,' 

 and thus clearly distinguished them from the younger gneissic 

 and micaceous crystalline rocks of the Central and P]astern 

 Highlands, which were classed as metamorphosed Lower 

 Silurian." 



Logan was not a voluminous writer, and during the later 

 years of his life writing was a great effort to him. Occasional 

 papers from his pen have appeared in the Transactions of the 

 Oeological Society of London, in the Oinadian Naturah'si and 

 the Canadian Journal, and some of these have already been 

 referred to ; but most of what he has written is to be found in 

 the Reports of Progress annually submitted to the Government, 

 and in that invaluable book, the Geology of Canada, whicb is, 

 to a large extent, a digest of what is contained in the reports 

 published previous to 1863. He sometimes expressed himself 

 quaintly, but everything he wrote is clear and exceedingly 



In addition to being a Fellow of the Royal Society and of 

 the Geological Societies of London and Paris, be was a member 

 of numerous other learned societies both in Europe and America. 

 At the time of his death, and for many years previous, he was 

 one of our Vice-Presidents ; but though 'frequently solicited to 

 accept the ofE.ce of President, he always declined, — not on ac- 

 count of any lack of interest in the Society, but he felt his 

 time was too fully occupied to permit of his successfully dis- 

 charging the Presidential duties. We have already alluded to 

 some of the medals which were awarded to him ; but it may be 

 mentioned that altogether he was the recipient of more than 

 twenty, including two from the Royal Society. 



And now, in concluding, let me say to you, my friends, if 

 you would do honor to the memory of that noble old man, who 

 fought so long, so bravely, for his country, for science, for you, 

 then honor the cause for which he fought : strive with all your 

 might to advance the interests of that cause, and to raise up a 

 superstructure befitting the solid foundation which Logan has 

 laid. He himself even hoped to build the superstructure ; but 

 his anticipations were not realized, for life was not long enough, 

 and we must take up the mantle which he has dropped. 



B. J. HARRINGTON.
