Title of Nobility Clause -- In 1810, Democratic--Republican Senator Philip Reed of Maryland introduced a Constitutional amendment modifying the Title of Nobility Clause. Under the terms of this amendment any United States citizen who accepted, claimed, received or retained any title of nobility from a foreign government would be stripped of their U.S. citizenship. After being approved by the Senate on April 27, 1810, by a vote of 19--5 and the House of Representatives on May 1, 1810, by a vote of 87--3, the amendment, titled ``Article Thirteen'', was sent to the state legislatures for ratification. On two occasions between 1812 and 1816 it was within two states of the number needed to become a valid part of the Constitution. As Congress did not set a time limit for its ratification, the amendment is still technically pending before the states. Currently, ratification by an additional 26 states would be necessary for this amendment to be adopted.

African dwarf frog -- These frogs are suggested to be kept in a group of two or more due to their social nature. Despite being fully aquatic, the African dwarf frog still needs to be able to reach the surface to breathe. These amphibians are not great swimmers, so water currents should be kept low and deep tanks may pose a challenge to their ability to breathe. In the wild, the Congo forest floods yearly to a depth of 24 inches or more, so any depth less than that will be suitable. They also should be kept in an enclosure with a secure cover to prevent escape and plenty of hiding spaces as in the wild they tend to be prey to a variety of animals and open spaces cause skittish behavior. The frogs eat any smaller fish. The optimum water temperature is 75--82 °F. The pH of the water should be maintained between 6.5 and 7.5. These frogs cannot survive out of water for longer than 20 minutes in low humidity, as they dry out.
