Mr. Henry M. Ami, student-in-arts at McGill then read a 

 very interesting paper on the " Utica Slate Formation in Canada," 

 with special reference to the deposits occurring in the vicinity of 

 Ottawa city, where the writer of the paper has been making 

 investigations and collecting specimens for the past three years. 



In the course of the paper, the origin, the mode of deposition, 

 the mineral and the lithologioul characters, ns well as the fossils 

 of that formation, were considered. Some new and interesting 

 notes on Triarfhus spinosus (Billings) were given. Several 

 species were added to the Canadian list of fossils from the Utica 

 slate. In the list of fossils appended to the paper, sixty-six (QQ) 

 species were given as occurring in different localities throughout 

 Canada of which only thirty-two have been previously recorded. 

 It was also mentioned that in the United States the total number 

 of species belonging to that formation, as recorded by Mr. C. 

 D. Walcott was exactly one hundred, and that consequently the 

 diligent searcher of Canada should be amply rewarded, as there 

 remain still some thirty-four (34) species to fill up our list and 

 make it as complete as that of the United States. 



Dr. Dawson then made some remarks concerning the whale 

 at that time on exhibition in the city, showing the dilB&culty of 

 classifying the whales on account of our meagre knowledge of 

 specific characteristics. Total length of specimen is 48 feet. 

 circumference 20 feet. Its head is 11 feet in length, with lower 

 jaw wider and deeper than upper. 



[The balance of Proceedings to date is left over to next number 

 through want of space.]
