REFERENCES
Is it true? Did it really happen? The implications and correlations are my own, and some of the accounts on the previous pages are based on my experiences. But many of the facts come from the writings of others. Where the incidents are well known no documentation is given. But when the behavior described is little known or only recently discovered I've given a reference so that the source can be consulted. These are arranged under the appropriate chapter headings.
