N. Fenton, and William C. Sturtevant. All have made important 

 suggestions as to what the content, specific and general, of this study 

 should be, have corrected errors in the drafts, and have indicated their 

 interest in the project at those times I most needed such reassurance. 

 For all this, I am grateful. In spite of their best efforts, errors and 

 inadequacies remain and for these, the responsibility is mine.
