Throughout the canon, Sherlock Holmes demonstrates an interest in chemistry. Watson refers to his knowledge of chemistry as "profound" (Study in Scarlet), and later as "eccentric" (Five Orange Pips). His Baker Street residence had a "chemical corner" in which he conducted many experiments. When Watson first met him in a chemical laboratory at Bart's, Holmes had just developed a reagent that co- precipitated with hemoglobin. At one point (Final Problem) he wistfully expressed a desire to concentrate his attention upon his chemical research. Indeed, during Holmes' forced travels, following the Reichenbach Falls incident, he spent some time on research into the "coal-tar derivatives" at Montpellier (Empty House). |
