A formal tea party, hosted by Lady Edwina Wolford-Bingham and attended by many of the finest members of London's high society, was spoiled Sunday by the appearance of an ocelot. 'Oh, dear,' said Lady Wolford-Bingham, whose father, Lord William Alfred Shropshire-Wolford, was a third cousin of Winston Churchill's. 'There appears to be an ocelot at my tea party.' In addition to 'badly scratching' Lady Catherine Norwich Baker Putnam-Howe, the angry ocelot overturned a number of tables and broke an expensive vase.
