of priority of discovery of chloroform has become a matter of National interest, and has been variously awarded to Guthrie, in America, Soubeiran, in France, and Liebig, the celebrated German chemist. According to some evidence, the discovery of chloroform can be traced back to the year 1831. In a letter to Professor Silliman dated February 15, 1832. Mr. Guthrie claims that the substance obtained by washing it with a strong solution of potassium carbonate was considered as "distilled off sulphuric acid." Guthrie's process was repeated and verified by Silliman at Yale before the end of 1831, whereas Soubeiran's publication in the Journal de Pharmacie appeared in January 1832, and his claim to priority over Liebig in the Annales de Chimie et de Physique did not reach the public until February. His letters detailing these chemical substances were published in the American Journal of Science in 1832, with editorial commentary, and reproduced in The Complete Writings of Samuel Guthrie the following year. Guthrie's "chloric ether," created by distilling lime chloride with alcohol in a copper still in 1831, turned out to be chloroform, and the discovery was later applied in the medical field as a mild anaesthetic in amputation surgery. Legacy Clinic in his honour Guthrie Ambulatory Health Care Clinic, opened in January 1991, and in May was dedicated to the memory of Samuel Guthrie. His up-to-date library In 1827, Guthrie helped to establish the Hounsfield Library, which contained roughly 500 volumes, and he served as one of its trustees. The doctor's library received much attention. In it were to be found the standard medical and chemical works, the scientific journals, the Edinburgh Encyclopædia, Shakespeare, and novels including; Rasselas, Gil Blas, Don Quixote, and the Bible, in which he was well read. These he contemplated with the most profound admiration and reverence.
