Dr. Snow found the cesspoolintended for a trap, but misconstructed, and upon and over a part ofthe cesspool a commonprivy, without water supply,for the use of the house hadbeen erected.

A washed appearanceof the ground and gravelflow corroborated this as-sumption. The ground be-tween the cesspool and thewell was black, saturated, and in a swampy condition, clearly demonstrating the fact. This evi-dence, while only circumstantial, is sufficient to connect the cesspool withthe well, and can leave no doubt in the minds of those who study thisinteresting and instructive instance that the water became infected withcholera germs through this channel.
