Hi Mr Data, Many thanks for that swift and superb response, it's much appreciated. I'm researching a person who had a riding accident during a hunt on that day. An eyewitness report says that the horse 'floundered' just before a jump, causing the accident. The wet weather conditions tie in with a horse floundering in mud or a morass, rather than slipping in the ice or frost more usually associated with January in the first half of the 20th century. Thanks again.
