AUTHORS PREFACE. Is 



name and address of a lady in Wisconsin, whose letter I received 

 while preparing this last work, presuming she will take no offense, 

 as I give her name and letter only to prove to the public in what 

 esteem my former books are held by those who have them. The 

 following is from Mrs. 0. N. Alden, and dated at Neenah, 

 Wisconsin : 



Dr. a. W. chase, 



Dear Sir: 



It is not the author or compiler of every book who 

 himself so permeates the contents that the reader feels in the author a per- 

 sonal acquaintance, but when I am consulting Dr. Chase's Books, it seems 

 as though I was personally consulting him, and that he is a friend, he makes 

 what is therein so individual. But, by so doing, he exposes himself to, per 

 haps, annoyance, as in this instance, by being personally addressed. * * ♦ 



The writer closes by relating her own condition of health, 

 and making inquiry as to the character of goods made by another 

 gentleman. I mention these circumstances among hundreds of 

 others only to illustrate to those having neither of my former 

 books what those who do have them think of them, hoping thus 

 to convince the million that my third and last book shall, at least, 

 be equally valuable. I have, however, done my best to produce a 

 work in every respect superior to my former ones, and with the 

 aid of thirty years' experience since my first book was published, 

 during which time many new theories have come into vogue and 

 many valuable discoveries have been made, I am confident that 

 I have succeeded, and can only hope that mj'- former works have 

 opened the door to this, my Crowning Life Work, and that it 

 will be a welcome visitor at every home, where either or both the 

 first and second books have found their way and prove to be 

 worth many times more than the sum paid for it 



THE AUTHOR 



Just two months after completing this work, and writing the foregoing 

 preface, the "Old Doctor" passed away and his spirit took its flight to Go4 

 who gave it.
