ity with which the trees can be grown, renders this a 

 somewhat important source of sugar. The paper also con- 

 tained determinations of sugar in the sap of the true sugar 

 maple {Acer saccharinum), the red maple {Acer rubrum) and 

 the butternut (Juglans cinerea). 



The most important paper of the section related to " The 

 Digestibility of Certain Varieties of Bread," by Dr. E. F. 

 Buttan, of Montreal. The results stated were derived from 

 a series of experiments on bread made with yeast, baking 

 powder, &c, and included statements relative to the retard- 

 ing influence of several mineral salts upon digestion. 



Other papers of this section were as follows : — 



" On a Specimen of Canadian Native Platinum from Bri-

 Crystals, in Eelation to Stellate Crystallizations Generally," 

 by Prof. E. J. Chapman ; " The Indirect Analysis of Phos- 

 phate Samples, as a Check on Commercial Analyses," by 

 Prof. B. J. Chapman; "Extension of the Use of Oblique 

 Co-ordinates in Geometry of Three Dimensions," by Dr. 

 Johnson, and " Investigation as to Maximum Bending 

 Movements at Points of Support of Continuous Girders of

In Section IV. papers of very great interest and value, 

 and embracing more than the usual range of subjects, were 

 presented. Those by Sir Wm. Dawson " On the Correlation

 Canada with that of Western Europe," and "Notes on 

 Fossil Woods from the Western Territories of Canada," are 

 printed elsewhere in abstract. 



The address by the President of the Section, the Abbe" 

 La flam me, specially related to Dr. Sarrasin as one of the 

 most eminent of the earlier scientists of Canada. Dr. Sar- 

 rasin was Eoyal Physician at Quebec in the early part of 

 the 18th century. He was deeply interested in the study
