Nearly three centuries later in 1872, another British observer quipped of this same ceremony: “The populace regard this ceremony with excessive superstition. Upon the retirement of the imperial cortege, they rush with eager haste to the opening, anxious to touch the consecrated stream, and fill pitchers from it to carry home. Even infants have been sent with their nurses to be plunged, under the idea that if the immersion is endured they will be fortified to bear all the perils of life.” See Thomas Milner, The Gallery of Geography: A Pictorial and Descriptive Tour of the World, Volume II (Glasgow: W.R. M’Phun & Son, 1872), 748.
