Here are some one liners...
Damn the Yankees! The Farren Riots of New York -- An angry remark by a British subject sparks a race riot but it probably would have occurred anyway.
Welcome to the German Union! -- A few German city-states establish a free trade zone to challenge the economic power of England. This Union will grow and become the model for trade unions to come.
Faraday Discovers the Law of Electrolysis -- I give a couple of examples and talk about what the average homeowner and boat-owner should know about it.
In Other News -- Parliament is burning, the American electric motor, and Whistler's mother.
Damn the Yankees! The Farren Riots of New YorkGeorge Farren is the stage manager for a Bowery theater and a British subject. Exactly how he caused a race riot in New York seems improbable, but a series of vaguely related events has led to a firestorm. A local newspaper owned by the Tappan brothers has been agitating for the abolition of slavery. More than that, Arthur Tappan recently sat with a negro friend during church services. Rumors spread that Tappan had divorced his wife to marry a black woman and that black men are prancing around town, all gussied up and looking for white wives. There are more serious rumors that gangs of black men are preparing to set fire to the city. This is coupled with a recent wave of Irish immigrants with their own fears and prejudices. The July 4th celebration of the New York emancipation of the slaves is rescheduled to July 7th after a misunderstanding leads to a fight between whites and blacks. Then George Farren fires an actor favored by the pro-slavery movement. After getting grief, he remarks, "Damn the Yankees; they are a damn set of jackasses and fit to be gulled." It all comes apart after that. George manages to save his own skin by bringing out an actor who entertains the crowd with a demeaning song about black people sung to the tune of "The turkey in the straw". (Don't make me repeat the title.) The riots go on for 4 days. The police are overwhelmed. The church of an abolitionist preacher is burned to the ground. It is an ugly business and we have not seen the last of it.       
Welcome to the German Union!The German Customs Union is a free trade zone between several German city-states. It is like the European Union without that self-absorbed, officious, piece of ... uh... I mean it has the EU benefits without the EU central government. The negotiations began after the fall of Napoleon who had created the German Confederation. They had returned to the protective trade barriers which increased the costs of goods. With the rise of England as an economic power, the European states had to band together to compete. The German Customs Union is one solution. Austria is not part of the Customs Union since the Prince of Austria prefers more strict control. (Actually, he hates the whole Free Trade idea.) Over the next few decades the Union will expand to include more German provinces and several non-German states such as Sweden-Norway. Then many of the German states will consolidate politically into the Northern German Confederation and after that, the German Empire. The economic relationships will take twists and turns, break apart for a year and reform again stronger than ever. The Union will eventually be replaced by the Wiemar Republic in 1919 and we all know how well that is going to go.   
Faraday Discovers the Law of ElectrolysisWhat is electrolysis? Certain chemical reactions will occur with a slight electrical charge flowing through a solution. The electrical charge allows certain materials to move from one place to another at the molecular level. Thus one can use electrolysis to place a fine coating of metal onto another. This is called electroplating. I am oversimplifying. Just know that your average lead-acid battery works using electrolysis as it discharges and recharges. Lead-acid batteries can produce a little hydrogen if not properly charged, but not a lot. I can imagine OTHER electrolysis applications that could produce large amounts of hydrogen. A word to the wise is sufficient. I hope everyone out there is wise enough to use caution.
