Your knowledge is outstanding. As for Robert's question, he has a valid point...being trained to go into the woods and look only for evidence of death. I know my "training" in the woods is to look for old bottles and other artifacts after a flood, and I once found an old, small, greenish bottle dated 1852, some sort of "jaundice bitters" that probably contained opiates and/or alcohol. It wouldn't cured the jaundice but would sure have made the patient forget about it! :D
