Chemical Lectures of H.T. Scheffer

I carne upon this collection o£ 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 o£ Bergman (Coronado Press, 1985). I have written a chapter about "Sche££er's Lec­ tures" in my Bergman biography. I refer the reader to this biography for further discussion. Bergman says in his "Foreword" to "Sche££er"s Lectures" that he designed this collection £o~ use by "those like me who teach chemistry". So this is one o£ the first, i£ not the first, textbooks de­ signed to be used in classes in chemistry. That phrase. "one o£ the first. i£ not the £irst". is so typical o£ Bergman's work in many fields. Bergman is considered to be the father o£ quantitative chemical analysis, physical chemistry, modern chem­ ical nomenclature, the concept o£ equival­ ent weights. and the electromotive series.
