Ketonuria: A condition in which abnormally high amounts of ketones and keytone bodies (a byproduct of the breakdown of cells) are present in the urine. Ketonuria is a sign seen in diabetes mellitus that is out of control. Diabetics prone to ketonuria need to monitor their urine for signs of ketone buildup that could lead to life-threatening symptoms unless promptly treated. Ketonuria can also develop as a result of fasting, dieting, starvation and eating disorders.
Income Tax was announced in 1798, and introduced in 1799, as a means of paying for the war against the French forces under Napoleon. France was threatening to invade, and had already landed briefly in Wales and Ireland. For much of his campaigns from 1795, Napoleon was better organised than the British forces.
In 1913, the Sixteenth Amendment to the U.S. Constitution was ratified authorizing Congress to impose a tax on income, and the Bureau of Internal Revenue was established. In the 1950s, the agency was renamed the Internal Revenue Service and significantly reorganized.
