Science, magnifying glass, microscope: These are Sherlock Holmes' tools

Read the section "Knowledge Alone Is Not Enough." Select the paragraph that suggests Holmes' use of technology put him ahead of his time.

• Dr. Robert Ing, a scientist and a Sherlock Holmes scholar, has closely read Doyle’s stories. Ing has his

  own list of skills that Holmes demonstrates a working knowledge of: chemistry, bloodstains, plants, the

  rocks and earth, the human body, law, secret codes, fingerprinting, document examination and

  medicine, among others.

• But knowledge by itself is not enough. Holmes had to put these skills to use to find and

  understand clues. He relied on the visual technologies of the time: a magnifying glass and a

  microscope. By today’s standards, these tools, of course, are not advanced. But in Holmes'

  original time, they were on the cutting edge, and the ones he used were incredibly exact and well

  made.

• In his paper “The Art of Forensic Detection and Sherlock Holmes,” Ing deduced Holmes would have

  most likely used a 10 power silver and chrome magnifying glass and a brass three-legged monocular

  optical microscope manufactured by Powell & Lealand. The brands for these tools are never mentioned

  in any story. Ing, though, notes they were the most popular at the time.
