PROBLEM 230 257 



Problem 229 : To consider some harmful habits. 



a. Tobacco 



Method. Allow the smoke from half a dozen cigarettes to 

 pass through the water of a small jar containing a goldfish, or 

 add a small piece of tobacco to the water. 



Observations. What is the result? 



Conclusion. Might tobacco have any similar effect on other 

 living things, as man? 



b. Alcohol 



Method and Observations. Using the figures given in your 

 Civic Biology, on pages 363, 369, 370, 371, explain why life insur- 

 ance companies consider moderate drinkers an extra risk. 



Conclusion. What effect does the drink habit have upon 

 man?

 scientific liter alness, wiped out. Of course this has its good side 

 as well as its bad one. As we become permanent drunkards by 

 so many separate drinks, so we become saints in the moral, and 

 authorities in the practical and scientific spheres, by so many 

 separate acts and hours of work. Let no youth have any anxiety 

 about the upshot of his education whatever the line of it may be. If
