 not impaired. On the other hand the additional 

 literary matter added has not only increased the 

 number of pages, but will, it is hoped, enhance the 

 value of the work to a very great extent. In its 

 present form Potter's Cyclopaedia should prove useful 

 to every person who handles drugs or herbs in either 

 a small or large degree.
