Rufus Wheeler Peckham, Mitchell v. Potomac Insurance Company…
“ Upon that the court charged:'Now, gentlemen of the jury, when the word 'explosion' was used in the policy, the company as ordinary men,-at least its officers were ordinary men, and not, as I assume, scientific men, and the party insured an ordinary man, are presumed to have understood the word 'explosion' in its ordinary and popular sense. Not what some scientific man would define to be an explosion, but what the ordinary man would understand to be meant by that word. ”
