OBSERVATIONS ON ANTIMONY, Read before the MEDICAL SOCIETY of LONDON, And published at their Request, BY JOHN MILLAR, M. D. LONDON: Printed for J. JOHNSON, No. 72, St. Paul’s Church-yard, and D. WILSON and G. NICOL in the Strand, MDCCLXXIV. TO THE MEMBERS OF THE MEDICAL SOCIETY OF _LONDON_. GENTLEMEN, The following observations having been honoured with your approbation, are now published at your request, and presented to you as a testimony of the author’s respectful regard. Candour requires him to acknowledge that some gentlemen of the Society were averse to the publication, judging that the free censure of popular opinions would rather provoke resentment than produce reformation. Not deterred from his purpose, he has availed himself of their friendly cautions to obviate some objections which may be made to the design. The account of the earlier chymists may, on a superficial view, appear superfluous; but it was thought necessary to illustrate the Medical History of Antimony, and to shew how little credit is due to those writers whose exaggerated praises of that medicine have contributed so much to mislead and abuse mankind. It may be objected that the author has not himself assayed the antimonial ores, nor repeated the chymical processes. But by drawing the chymical and mineralogical materials from other sources, all imputation of prejudice or partiality, on his part, is prevented, since he appeals to the testimony of the patrons of antimony themselves, for the authenticity of the facts by which some of their opinions are subverted. I am, GENTLEMEN, Your most obedient, and most humble servant, JOHN MILLAR. Pall Mall, April 2, 1774. THE CONTENTS.
