And like Rabbis find out Cabalism, and ænigmas in the Figure, and placing of Letters, where no such thing lies hid: whereas in natural forms . . . the more we magnify the object, the more excellencies and mysteries do appear; and the more we discover the imperfections of our senses, and the Omnipotency and Infinite perceptions of the great Creator.''
