PREFACE. 
7 
In my anxiety to be understood by all classes of 
readers, I am aware that I have made the elegant con- 
struction and arrangement of sentences of secondary 
importance; therefore justly liable to criticism. But 
to the reader, whose object is information on this sub- 
ject, it can be of but little consequence.
