Garrison-Morton 1102; Norman 1069 (vols I and II only); Wellcome III, p.259. - RARE FIRST EDITION in book form of Vol. III; Hewson advanced knowledge of blood during the 1770s, when the microscope was little used because of distortions caused by compound lenses. Hewson used a single lens, and discovered a satisfactory way to mount "wet" specimens on slides, and so was able to ascertain the role of fibrogen, and give the first valid account of coagulation; to give the first account of the anatomy and production of lymphatics, and to describe clearly the three parts of the blood. - The third volume was published posthumously by Magnus Falconer. Hewson's experimental findings were first published in 3 contiguously papers in the Philosophical Transactions of the Royal Society London in 1771 (see Garrison-Morton 863).
