Although William T.G. Morton is well-known for performing his historic anesthesia on October 18, 1846, C.W. Long is now known to be the first doing an ether-based anesthesia.
After observing the same effects with ether that were already described by Humphrey Davy 1800 with nitrous oxide, C.W. Long used ether the first time on March 30, 1842 to remove two tumors from the neck of his patient, Mr. James M. Venable. The results of this trials were published several years (1854?) later only being second after Morton's publication. An original copy of his publication is held in the U.S. National Library of Medicine.
Young Williamson's maternal grandfather was a lapidary, and from him he learnt the art of cutting stones, an accomplishment which he found of great use in later years, when he undertook his work on the structure of fossil plants.
His long course of researches on the structure of Carboniferous plants belongs mainly to the latter part of his life, and his results are chiefly, though not wholly, embodied in a series of nineteen memoirs, ranging in date from 1871 to 1893, in the Philosophical Transactions.
After a long controversy the truth of Williamson's views has been fully established, and it is now known that the mode of growth, characteristic in present times, of dicotyledons and gymnosperms prevailed in Palaeozoic ages in every family of vascular cryptogams.
