Although covering a large number of compounds and more importantly indicating reference sources for the mixture of names for the same compounds, missing is any reference to pharmacological uses. Based on his previous books, I was expecting some indication of known psychopharmacological effects for at least some of these compounds. Certainly the authors would have come across some in putting this book together. Also, I disagree that the Chem Abstracts number (CAS #) is useless, especially with compounds that have multiple common names. Simply including the CAS where known would not have taken up much space and then could be used to search for more applicable literature.
