How to Draw Eyes - The Cyclopedia Book of Plates

These images of the anatomy of the eye are from a book titled The Cyclopedia Book of Plates dated 1809.  I am not sure which Cyclopedia they are from. The Encyclopedia Britannica was in print at that time as was Ephraim Chamber's Cyclopedia.

Both prints are for sale on Ebay.
