A couple of months ago, in a thread involving a method mentioned in Hoke's book that is not favored on the forum, one of our members (John (username JHS)) posted that: "everyone that comes here is told to read hoke.NO one is told that you do not boil.if there are processes that are in hokes book that are dangerous and newcomers read that in hoke and are not for warned,they are being put in harns way.".
My initial reaction was irritation as I knew I
had included several warnings in my printer friendly version. I quickly checked it and found... he was right. There was no warning not to "boil" a solution when the intention was to evaporate. While I believe Hoke only used the word "boil" in this context twice, it could cause problems for readers who do not recognize the error, as "boil" and "boiling" are appropriately used elsewhere in the book. Because of John's comments, I have reread the book looking for misinformation, hazards, outdated methods, and other information that could cause a new reader problems or put them in conflict with the members of the forum.
Since it does not make sense that whenever recommending the book we need to add a list of warnings, I have added them to this revised version. I have created an "Introduction" which is now included in my versions of the book to describe the issues I found. Thank you John for pointing out an area where I could improve. I have placed the Introduction on 4 new pages of the pdf file and inserted them between Hoke's Acknowledgement page and the Preface. If the reader does not want them in their book, they may exclude these pages, the fifth through eighth pages, of the pdf file.
In addition to adding the introduction, I've corrected some more typographical/OCR errors and tweaked some of the images. I also borrowed a few ideas from Rusty (rewalston) and griptheweasel to create a new cover that honors the author. The current file is a bit larger than the previous one because of the improved images.
I want to express my gratitude to 4metals, butcher, freechemist, goldsilverpro, Harold_V , lazersteve, and Lou for their help on this project. I also want to thank everyone who has provided links to this thread. Without them, we wouldn't have had over 1,100 downloads. Finally, I want to thank Pat (Pattt) who found many of the typographical/OCR errors I was able to correct in the current versions. I have replaced the version in the original post with the new version.
Merry Christmas everyone!
Dave
You may have noticed that I said version
s. I have created a screen readable version with all of the corrections and improvements of the printer friendly version. You can see it here:
