Some people have a thing with weather. My Uncle J., as he was called in the family, liked to hold forth on his hobby. Uncle J. was highly educated, having Doctorates in Latin and Synoptic Meterology. He always said his memory and mind were on overload and he needed to be reminded of things. This was before Post-It notes... He carried an aneroid barometer in his left pocket and a small alarmclock in his right. Uncle J. was certain the best instruments were designed for ships and seafaring. That's perhaps why a brass tide clock and a weather glass where centrally positioned in his study. He delighted in having people try to name the kind of liquid in his weather glass.
