“In my opinion,” said Lydgate, “legal training only makes a man more incompetent in questions that require knowledge of another kind. People talk about evidence as if it could really be weighed in scales by a blind Justice. No man can judge what is good evidence on any particular subject, unless he knows that subject well. A lawyer is no better than an old woman at a postmortem examination. How is he to know the action of a poison? You might as well say that scanning verse will teach you to scan the potato crops.”

“You are aware, I suppose, that it is not the coroner’s business to conduct the postmortem, but only to take the evidence of the medical witness?” said Mr. Chichely, with some scorn.

“Who is often almost as ignorant as the coroner himself,” said Lydgate. “Questions of medical jurisprudence ought not to be left to the chance of decent knowledge in a medical witness, and the coroner ought not to be a man who will believe that strychnine will destroy the coats of the stomach if an ignorant practitioner happens to tell him so.”
