After the back was affe&ed, the difeafe extended 
itfelf very faft ; fo that by the end of September, al«

From the end of September to the middle of 
November, the difeafe, as though it had exerted all 
its power, was at a ftand. The feveriffi heat had 
left her, and her pulfe beat generally between eighty
