"In one of these courts there stands directly at the entrance, at the end of the covered passage, a privy without a door, so dirty that the inhabitants can pass into and out of the court only by passing through foul pools of stagnant urine and excrement. Below it on the river there are several tanneries which fill the whole neighbourhood with the stench of animal putrefaction.
