 window, but kept in a dry close cupboard. — Syniprisometer, Adie's pa- 

 tent Mountain, in same situation as Barometer. — Maximum Thermometer, 

 is a horizontal one by Newman ; hangs in an unoccupied room on the first 

 story ; aspect North, and window and door always open. — Minimum, hori-

 house twenty-five feet above the ground, and ninety-nine above the sea.
