a flame is a burning gas and that a solid, as carbon, burns with- 

 out a flame and will be able to form an intelligent conception 

 ol many processes in nature and the arts which would otherwise 

 be quite inexplicable. , 



The main topic in these lessons for this work covers several 

 lessons is chemical union ; but the ether topics discussed are 

 important and all of them help in making clearer the idea of 

 chemical union. And this illustrates another method of making- 

 our teaching more effective and saving time in the process. I 

 mean that while we keep in view one principal topic we should 

 always associate it with ethers which are significant and worth 

 teaching in themselves and at the same time are so related to the 

 central topic that they can be used effectively in enforcing it.

 session Summer School was held at the Normal School, Ottawa,
