As the island of Grenada is highly volcanic in parts, it is not 

 improbable that the observations may be affected to some extent by 

 local disturbance.

The observations at Carriacou were much interfered with by rain, 

 and no determinations of dip were possible. The moment of the 

 magnet has been assumed to be that determined at Hog Island on the 

 p re \ious day.
