Please note Bob's comment to the wonderful picture he posted of Isaac Newton Russell.  This prompted me to post the above pictures in a book written by Isaac Newton "The First Book of Opticks" which I found in the effects of my Grandfather (HHB).  I think this fourth edition was written (in old English) somewhere in the middle 1700's.  Maybe he took this to Stevens with him as a student?  Could there be any connection to Sir. Isaac Newton and Isaac Newton Russell?
