First edition, title-issue. "Mohr’s most lasting contribution was in titration. His Lehrbuch... Titriermethode was the first successful compendium in this new field of analytical chemistry; It went through eight new editions between 1856 and 1913 and was translated into several languages. Mohr invented many new titration procedures and examined and often improved most of the older ones. Many methods and designs of apparatus bear his name: the Mohr test for iron and chloride determination, the Mohr pinchcock burette, the Mohr balance for the determination of specific gravity, and Mohr’s salt (ferrous ammonium sulfate) are evidence of his skill in the laboratory. The cooling device generally called the Liebig reflux and the useful cork borer were also invented by Mohr." (DSB).
