SECOND MAGNETIC POLE DISCOVERED .
MAGNETIC SYSTEM OP THE NORTHERN HEMISPHERE ; AS OBTAINED FROM A MAGNETIC ROCK , IMPRESSED WITH A CIRCULAR SEGMENT = ARC OP GO " , PROCURED AT GWAMOR ; AND DEMONSTRATED TO THE RIGHT HONOURABLE LORD AUCKLAND , GOVERNOR-GENERAL OP INDIA , AT VUTTEHGUR , ON Hill JANUARY , 1838 , BY ROBERT TYTLER , M . D .
Boothia Pole discovered 1 st June , 1831 , —Gwalior Pole demonstrated , on January 11 th , 1831 . Boothia extreme mundane cold ; Gwalior extreme mundane heat ; the Poles are , therefore , opposite , being the extremes of Terrestrial Cold and Heat .
