Dean Dorothy Stimson, in a recently published paper, has independently arrived at this same conclusion.  She points out that of the ten men who constituted the "invisible college," in 1645, only one, Scarbrough, was clearly non-Puritan.  About two of the others there is some uncertainty, though Merret had a Puritan training.  The other were all definitely Puritan.  Moreover, among the original list of members of the Society of 1663, forty-two of the sixty-eight concerning whom information about their religious orientation is available were clearly Puritan,  Considering that the Puritans constituted a relatively small minority in the English population, the fact that they constituted sixty-two per cent of the initial membership of the Society becomes even more striking.  Dean Stimson concludes: "that experimental science spread as rapidly as it did in seventeenth-century England seems to me to be in part at least because the moderate Puritans encouraged it" (1968, pp. 638-639).
