Princess Caraboo of Javasu and the Price of CharityA pretty young woman in black, shows up at a cottage in Gloucestershire. She needs lodging, but she speaks no language that can be understood. Eventually she is brought before the county magistrate who discovers that her name is Caraboo, and after seeing a map of the world, she points to China. (She is obviously Asian!) Later, a Portuguese sailor attests that he knows the language she speaks, that she is a princess from the island of "Javasu", kidnapped by pirates and then escaped the ship and swam ashore. (Who can argue with that?) She writes using strange symbols which have been verified by an expert... that is, a doctor found similar symbols in a book. She prays to a strange god, and she swims naked. (She must be a foreigner because she does strange things that make no sense.) If this all sounds like a load of hooey, you are correct. Her real name is Mary Baker. She is an out-of-work servant girl and for several months she convinces the locals that she is a princess until her picture appears in the newspaper, and someone recognizes her. Is that the end? NO! Her hosts pay for her passage to Philadelphia, but the ship is driven off course and comes to the island where Napoleon is held in exile. Now Napoleon wants to marry her! (Oh, please!) In 1994, the film entitled "Princess Caraboo" will be made of her life. The story contains some fictional elements.  
The First Cholera PandemicCholera is an intestinal disease caused by bacteria in contaminated food or water. It produces severe water loss and electrolyte loss due to diarrhea. The disease has been local, limited to the area around the Ganges River which is very big area in modern day India. With increased trade, the disease has spread outside of India. In the next few years it will be in Southeast Asia, Japan, Africa and Baghdad. It will come to the attention of Europeans when the pandemic kills 10,000 British troops. The total number of deaths during this pandemic are unknown. 100,000 deaths are reported in Java. 30,000 in Bangkok. The pandemic itself will die out by 1824 possibly due to colder than normal weather. In the year 1817 scientists are beginning to suspect that germs cause disease, but the germ theory of disease won't kick in until the late 1850s.
