The above table is given to indicate the relations of the various 

 members of the Ordovician (Cambro-Silurian) System in Canada 

 showing the position of the " Quebec Terrane " in the lower half of the 

 system instead of being classed or grouped along with the Hudson 

 River (= Lorraine) terrane at the very top of the system as formerly. 

 The exac: relations, stratigraphical and palseontological, which exist 

 between the Quebec, Levis and Sillery terranes have yet to be defined. 

 Their sequence aid order in the scale of time require further investi- 

 gations before this interesting fact can be ascertained on which Sir 

 Wm. Logan .ind Mr. Billings were still actively engaged when called 

 away.

NATURAL HISTORY OBSERVATIONS. 



A form for registering observations of the first and last records in 

 Natural History has just been issued by the Royal Society of Canada. 

 This form has been drawn up by a committee of the Royal Society and 

 distributed to the different Natural History and Scientific Societies 

 throughout thj country. Observations are asked for upon certain well- 

 known wild jilants in all the Provinces of the Dominion, the time of 

 sowing and harvesting grain and the ripening of wild and cultivated 

 fruits. Then follow the arrivals and departures of birds and the most 

 noticeable meteorological occurrences. 



There is no^doubt that the Royal Society will gather together by 

 this means most valuable information. It is proposed to have the 

 schedules collected once a year and the results laid before the Royal 

 Society for publication in their annual Volume of Transactions,
