TlvM'e are aiany and intricate problems involved in a detailed 

 study ri( the geological formations of the Province of Quebec. Particu- 

 larly .so is this the case respectinti; the sedimentary formaiions of the 

 south and eastern portions of this Province. 



Leaving out of consideration the unfossiliferous rocks of the dis- 

 trict, the paper deals with the more recent discoveries that have been 

 made in this region, and discusses their bearing upon the problems 

 involved. 



To the sum of palaeontological evidence adduced by the late Mr. 

 E. Billings, in effecting a correlation of the strata in question with their 

 equivalents in other and undisturbe J regions of Canada and elsewhere, 

 there has recently been discovered a fauna which may now well 

 be designated the Faun.i, (for a description of which the reader is 

 refened to the writings of Prof. Whitfield, by Profs. H. M. beely and 

 Ezra Brainerd, of Middlehuiy College, Vt.) and the relation of this 

 remarkable fauna to the faunas described by Mr. Billings from the 

 Philiii)sburg district as well as from the Scranbridge and intermediate 

 •regions are herein discassL-d Thus far. the views promulgated by 

 Billings and by Sir Williani Logan regarding the existence of a series 

 of geological formations deposited under peculiar conditions, and all 

 capable of being brought under the one continuous group or series 

 (designated by them the " Quebec Group '') are found to be correct. 



From the above it can readily be seen that in section IV. 

 of the Royal Society which deals with g-eological and biological 

 science gencrall}^, there was considerable activity. Besides the 

 presidential address, which, owing to its special nature, did not 

 come in for a share of discussion, there were general geological 

 papers, and some of these led to most important as well as 

 interesting and lengthy discussions. On Prof Penhallow's 

 paper relating to the Pleistocene Flora of Canada, a most inter- 

 esting discussion followed, in which were involved numerous 

 problems touching upon the climatic conditions at the time in 

 question. Subsequent to the reading of Sir William Dawson's 

 paper on the Metis Sponges and the Quebec Group of the 

 Lower St. Lawrence — as also after Dr. Ami's paper 

 to the same section on a similar subject to Sir William's 

 — there were important discussions in which Dr Ells, Dr. 

 Selwyn, Mr. Whiteaves, besides the authors of the papers tooi<
