1670. unbound. 1 page, 6 x 7.5 inches, no place, August 11, 1670. This exceedingly rare document -- a prescription written in Latin -- is boldly signed "Thomas Guidott, M.D." Some soiling and foxing, otherwise very good.
Guidott, Doctor of Physics, became the 17th century's most prolific scientist using the latest techniques of the time for analysis. In 1699 he published his first book documenting the curative properties of the warm springs native to Bath, England. He was the first medical doctor and scientist to recognize the health-giving properties of the hot mineral waters.
