The mother to be wrote to Washington for a pamphlet on the subject of "Prenatal Care". A few days later she received a reply regretfully informing her that the requested pamphlet was out of stock but as soon as it was available it would be sent to her.

Quite a few months passed and the lady received a package from the bureau. The Superintendent of Public Documents apologized for the delay and felt that under the circumstances they could take the liberty of substituting the pamphlet originally asked for with another, "Infant Care".
