Summary:

Activities at H.E.I.C. magnetic and meteorological observatories in Simla, Madras, and Singapore. Results from Simla, elevation 8000 feet, will complement high altitude observations in Europe. Vertical force instrument at Singapore is better than at all other stations, but high humidity there makes actinometer unreliable.
