The high point of her work in Washington was the Bill for the Benefit of the Indigent Insane, legislation to set aside of Federal land to be used for the benefit of the mentally ill and the remainder for the "blind, deaf, and dumb". Proceeds from its sale would be distributed to the states to build and maintain asylums. Dix's land bill passed both houses of the United States Congress; but in 1854, President Franklin Pierce vetoed it, arguing that social welfare was the responsibility of the states. Stung by the defeat of her land bill, in 1854 and 1855 Dix traveled to England and Europe. She reconnected with the Rathbone family and, encouraged by British politicians who wished to increase Whitehall's reach into Scotland, conducted investigations of Scotland's madhouses. This work resulted in the formation of the Scottish Lunacy Commission to oversee reforms.
