I carne upon this collection oGBP lec- tures in chemistry by Henric Theophil Scheffer delivered in about 1750, edited by Torbern Bergman and published in Swed- ish in 1775, when I was spending a sab- batical leave in Uppsala. Sweden. in 1977, gathering material for my biography oGBP Bergman (Coronado Press, 1985). I have written a chapter about ScheGBPGBPer’s Lec- tures in my Bergman biography. I refer the reader to this biography for further discussion. Bergman says in his Foreword to ScheGBPGBPer s Lectures that he designed this collection GBPo~ use by those like me who teach chemistry . So this is one oGBP the first, iGBP not the first, textbooks de- signed to be used in classes in chemistry. That phrase. one oGBP the first. iGBP not the GBPirst . is so typical oGBP Bergman’s work in many fields. Bergman is considered to be the father oGBP quantitative chemical analysis, physical chemistry, modern chem- ical nomenclature, the concept oGBP equival- ent weights. and the electromotive series.
