BTW, the case you refer to is Anthony Johnson vs Parker, concerning the servant John Casor. Here is a link to the document you referenced:

Sorry, but that does not look like the posting I remember. It was considerably longer, and the details of the case were different. If I have time and can find it, I will post a link.
