The recent exchange of anecdotes etc about various environmental toxins brings up something I have mentioned before: a nationwide, or even worldwide, registry of PD cases. There are scientists trying right now with limited data to correlate environment with incidence. Such a registry is not a task for amateurs. It would be a BIG project facing lots of difficult problems, such as what questions to ask, how to preserve privacy, how to account for incipient or undiagnosed cases, how to exclude cases that are not really PD, and so forth. But if environmental causes are important, as many people suspect, such a registry might reveal the answers we are all looking for. I think if not by some government organiz- ation (save us!) perhaps it could be undertaken by one of the civilian support institutions, if enough people start asking for it. Comment? J. R.
