Subject: Re: [A-L] an morbo nigro   It appears to be the Latin form of black disease ... which may be related to a liver disease mostly seen in sheep, but I think it may be safe to assume at that point that it was likely the Black death that was being written about. My latin is even more limited than my French and German. See the following book "De Morbo Nigro" by S.A.D. Tissot, MD 1760. http://books.google.com/books?id=g9A_AAAAcAAJ&printsec=frontcover&dq=Morbo+nigro&hl=en&ei=rHIOTvjPGcKltwfJn-SADg&sa=X&oi=book_result&ct=result&resnum=3&ved=0CDQQ6AEwAg#v=onepage&q=morbo%20nigro&f=false Hope this helps.
