ORDINARY MEETINGS. xl vit 
“The Institute desires to convey to Lapy Dawson and her family, 
an expression of the deep sympathy with which its members have heard 
of the sad bereavement she and her family have experienced.” 
A paper by Henry M. Amt, Esq., D. Sc., of the Geological Survey 
of Canada, “‘On the Sub-divisions of the Carboniferous System in 
Eastern Canada,” was read by Dr. E. Gitpin who gave an introductory 
statement of a popular character. (See Transactions, p. 162). 
The subject was discussed by Dr. Girpry, Me. J. Forses and others. 
The president, Dr. A. H. MacKay, said he was glad to have Dr. 
Ami’s views presented to the Institute. He spent a fortnight with Mr. 
Fletcher in running over the stream-expused sections of the southern 
flanks of the Cobequids ; and became deeply interested in some of the. 
problems discussed in the paper. The extremely careful work done of 
late years had thrown new hght on the problems attempted to be solved 
by the older geologists trom their original but more limited observations. 
Mr. Fletcher has reason to feel gratified that Dr. Ami and Dr. Dawson 
admit that his maps of the region in question ‘‘show clearly the true 
? 
and natural order of sequence of the formations ;” so that the reference 
to “ types that are everywhere held to be of carboniferous age” must 
indicate a revision of the older geological nomenclature of sume regions. 
Sir William Dawson, a most eminent paleontologist as well as geologist, 
after studying the fossil plants and animals of Riversdale, MacKay 
Head, and Harrington River, placed them in the Millstone Grit forma- 
tion as intimately related to those of the Coal Measures. Dr. Ami now 
correlates them with the Lancaster fern ledges (hitherto known as 
Devonian) of New Brunswick ; but he would place them all in his new 
Eo-carboniferous. Of the twenty-one fossil species enumerated by Dr. 
Ami, fifteen were Dawson’s own species. Pstlophyton glabrum belonged 
to a genus hitherto generally considered to be characteristic of the 
Devonian. Leaia Leidyi (perhaps identical with Leaza tricarinata) 
was found in rocks called Devonian by many geologists. Belinurus 
grandevus and Estheria Dawsoni represented genera usually considered 
common both to the Devonian and the Carboniferous, with specific 
names given to specimens obtained from the rocks in dispute. Dr. 
Ami’s new species Sawropus Dawsont was stated to be only “ apparently 
from rocks of this age.” Mr. Fletcher would appear to oppose the 
assumption that the rocks underlying the New Glasgow conglomerate.
