36 PLAIN FACTS FOE OLD AND TOUNG 



We have had the satisfaction of knowing, in numer- 

 ous instances, that the virtue and happiness of whole 

 families have been secured by the timely warnings of 

 danger which parents have obtained from this work- 

 We are glad to be able to feel that it is now thoroughly 

 demonstrated that intelligent persons who have given 

 this subject thought, universally approve of the objects 

 of the work, and the manner of presenting the subject 

 adopted in it. Those who at first question the propriety 

 of discussing the subject so freely and thoroughly as is 

 here done, lose their prejudice entirely upon giving the 

 work a careful perusal. In numerous instances it has 

 occurred that those who were most decided in their 

 denunciations, have become the most zealous and effi- 

 •jient agents in its circulation, after becoming more 

 rully acquainted with it.
