promotion of research. In the third section, mathematical, 
physical and chemical sciences, Mr, Macfarlane’s address 
was specially spoken of as indicating the industrial results 
of chemistry; Mr. Hoffman’s analyses of native Canadian 
platinum ; the contributions of Mr. McGill and Dr. Ellis to 
analytical processes ; Dr. Ruttan’s paper on digestibility of 
bread as affected by baking powders and alum; Dr. Har- 
rington’s observations on the flow of sap in the western 
maple; Mr. Coleman on microscopic petrography, and Mr. 
Bovey’s investigation in regard to girders. In the fourth 
section, geology and biology, the Abbé Laflamme gives a 
valuable contribution to the history of science and medicine 
in Canada, in a biographical study of Dr. Michael Sarrazin, 
whose name was linked by the renowned early French 
botanist, Tournefort, to our pitcher plant, Sarracenia, Prof. 
Penhallow’s review of Canadian botany from the first settle- 
ment of New France to the eighteenth century was fully 
referred to in special relation to the early connection of the 
history of botany in Canada and in Kurope; Dierville having 
carried Acadian plants to Tournefort, and Peter Kalm, of 
Abo, in Sweden, having, through encouragement of Linné,

he cultivated afterwards in his garden, whilst Menzies, the 
Scotch botanist who accompanied Vancouver, collected on 
our Northwest coasts and around the Halifax harbour before

in the affirmative, for the hoary bat, the question, Do any

H. Mackay, of Pictou, give a list of the marine alge of the

students, to whom these plants present an inviting aspect 
as an illimitable field for study of life histories. 
Dr. T. Wesley Mills, in his able paper on the mental 
endowments of squirrels, brings these creatures forward in 
a new light. Prof. Fowler tabulates the Arctic plants of 
New Brunswick, and Mr. Payne gives his observations 
made on the periodical phenomena of vegetation through-
