      Others have conſidered infinite Space as the Receptacle, or rather the Habitation of the Almighty : But the nobleſt and moſt exalted Way of conſidering this infinite Space is that of Sir Iſaac Newton, who calls it the Senſorium of the Godhead. Brutes and Men have their Senſoriola, or little Senſoriums by which they apprehend the Preſence and percieve the Actions of a few Objects, that lie contiguous to them.
