The Second Intermediate Period dates from 1700 to 1550 BC. It marks a period when ancient Egypt was divided into smaller dynasties for a second time, between the end of the Middle Kingdom and the start of the New Kingdom. The concept of a Second Intermediate Period generally includes the 13th through to the 17th dynasties, however there is no universal agreement in Egyptology about how to define the period.
Surgeon-Major James Africanus Beale Horton was a British Army officer, surgeon, writer and banker. Born in Gloucester, Sierra Leone into a Creole family who were liberated from enslavement by the Royal Navy, he began attending the SLGS in 1845. After graduating from Fourah Bay College, Horton received a War Office scholarship study medicine in Britain to prepare him for a career in the British Armed Forces, and he attended King's College London and the University of Edinburgh. Serving in the West India Regiments, Horton was posted to various locations within the British Empire, including Lagos, the Gambia, Sierra Leone and the Gold Coast and participated in the Anglo-Ashanti wars.

Tooting is an impact crater with volcanic features at 23.1°N, 207.1°E, in Amazonis Planitia, due west of the volcano Olympus Mons, on Mars. It was identified by planetary geologist Peter Mouginis-Mark in September 2004. Scientists estimate that its age is on the order of hundreds of thousands of years, which is relatively young for a Martian crater. A later study confirms this order of magnitude estimate. A preliminary paper describing the geology and geometry of Tooting was published in 2007 by the journal Meteoritics and Planetary Science, vol. 42, pages 1615–1625. Further papers have been published, including a 2010 analysis of flows on the walls of Tooting crater by A. R. Morris et al., and a 2012 review paper by P.J. Mouginis-Mark and J.M. Boyce in Chemie der Erde Geochemistry, vol. 72, p. 1–23. A geologic map has also been submitted in 2012 to the U.S. Geological Survey for consideration and future publication.
