The most interesting feature of all of Basil Valentine's writings that are extant is the distinctive tendency to make his observations of special practical utility. His studies in antimony were made mainly with the idea of showing how that substance might be used in medicine. He did not neglect to point out other possible uses, however, and knew the secret of the employment of antimony in order to give sharpness and definition to the impression produced by metal types. It would seem as though he was the first scientist who discussed this subject, and there is even some question whether printers and type founders did not derive their ideas in this matter from Basil Valentine, rather than he from them. Interested as he was in the transmutation of metals, he never failed to try to find and suggest some medicinal use for all of the substances that he investigated. His was no greedy search for gold and no accumulation of investigations with the idea of benefiting only himself. Mankind was always in his mind, and perhaps there is no better demonstration of his fulfilment of the character of the monk than this constant {75} solicitude to benefit others by every bit of investigation that he carried out. For him with medieval nobleness of spirit the first part of every work must be the invocation of God, and the last, though no less important than the first, must be the utility and fruit for mankind that can be derived from it. {76} {77} IV. LINACRE: SCHOLAR, PHYSICIAN, PRIEST. {78} Linacre, as Dr. Payne remarks, "was possessed from his youth till his death by the enthusiasm of learning. He was an idealist devoted to objects which the world thought of little use." Painstaking, accurate, critical, hypercritical perhaps, he remains to-day the chief literary representative of British Medicine. Neither in Britain nor in Greater Britain have we maintained the place in the world of letters created for us by Linacre's noble start. Quoted by Osler in _AEquanimitas_.
