The Opticke Glass of Humors was written by Thomas Walkington, an educated reverend. This is the first in the collection (chronologically) to be on a relatively unscientific topic. At least the subject of bodily fluids and the balance of humors has since been deemed unscientific. Walkington studied and worked as a fellow at Cambridge.
In 1664, this edition was printed in London for G. Dawson.
