Meriwether Lewis . . . depressed to the end

According to Scott Bonar, Meriwether Lewis was terribly depressed. He attempted suicide twice, once by trying to jump overboard from a steamboat. He then tried to shoot himself. Both of these attempts were made while on a trip east (from Louisiana, where he was governor) to explain why he wasn't a very good governor. In Tennessee Lewis rented a room in a cabin and then shot himself twice and then cut himself from head to toe with a razor (Bonar 2007). There aren't any pages that confirm what Bonar says here's a good background on Lewis. I like Bonar's book so far (The Conservation Professional's Guide to Working with People), though the uncertainty I have about Lewis actually cutting himself from head to toe is high.
