Abstract
In a previous paper (Powell 1937) an account has been given of the results obtained in Montserrat, from 24 March to 24 July 1936, with the physical apparatus installed in the island by members of the Royal Society Expedition. The present paper gives a more detailed account of the methods employed and the results obtained up to 8 July 1937 with the instruments maintained in the island, together with the conclusions which have followed from a more complete examination of the records. In addition, based on the experience gained during the course of the expedition, recommendations are made as to the most suitable type of instruments for the investigation of the particular kind of seismic phenomena which have occurred in Montserrat during the past 3 years.
