A Millbank bag is a portable water filtration device made of tightly woven canvas for outdoor use. [1] They are light, compact, and easy but slow to use. [2] The bag is filled with water, which filters through the canvas by gravity. It is useful for removing sediment and organic matter but the water may require further sterilisation before being drunk. [3]

Nain Singh, also known as Nain Singh Rawat, was one of the first Indian explorers employed by the British to explore the Himalayas and Central Asia. He came from the Johar Valley in Kumaon. He surveyed the trade route through Ladakh to Tibet, determined the location and altitude of Lhasa in Tibet, and surveyed a large section of Brahmaputra. He walked "1,580 miles, or 3,160,000 paces, each counted."
Sir James Hector was a Scottish-New Zealand geologist, naturalist, and surgeon who accompanied the Palliser Expedition as a surgeon and geologist. He went on to have a lengthy career as a government employed man of science in New Zealand, and during this period he dominated the colony's scientific institutions in a way that no single man has since.
Edward Adrian Wilson was an English polar explorer, ornithologist, natural historian, physician and artist.
Sir Halford John Mackinder was an English geographer, academic and politician, who is regarded as one of the founding fathers of both geopolitics and geostrategy. He was the first Principal of University Extension College, Reading from 1892 to 1903, and Director of the London School of Economics from 1903 to 1908. While continuing his academic career part-time, he was also the Member of Parliament for Glasgow Camlachie from 1910 to 1922. From 1923, he was Professor of Geography at the London School of Economics.
Carsten Egeberg Borchgrevink was a Norwegian polar explorer and a pioneer of Antarctic travel. He inspired Sir Robert Falcon Scott, Sir Ernest Shackleton, Roald Amundsen, and others associated with the Heroic Age of Antarctic Exploration.
William Speirs Bruce was a British naturalist, polar scientist and oceanographer who organized and led the Scottish National Antarctic Expedition to the South Orkney Islands and the Weddell Sea. Among other achievements, the expedition established the first permanent weather station in Antarctica. Bruce later founded the Scottish Oceanographical Laboratory in Edinburgh, but his plans for a transcontinental Antarctic march via the South Pole were abandoned because of lack of public and financial support.
Sir John Murray was a pioneering Canadian-born Scottish oceanographer, marine biologist and limnologist. He is considered to be the father of modern oceanography.

Sir John Kirk was a physician, naturalist, companion to explorer David Livingstone, and British administrator in Zanzibar, where he was instrumental in ending the slave trade in that country, with the aid of his political assistant, Ali bin Saleh bin Nasser Al-Shaibani.
Carex is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
The Scottish National Antarctic Expedition (SNAE), 1902–1904, was organised and led by William Speirs Bruce, a natural scientist and former medical student from the University of Edinburgh. Although overshadowed in terms of prestige by Robert Falcon Scott's concurrent Discovery Expedition, the SNAE completed a full programme of exploration and scientific work. Its achievements included the establishment of a staffed meteorological station, the first in Antarctic territory, and the discovery of new land to the east of the Weddell Sea. Its large collection of biological and geological specimens, together with those from Bruce's earlier travels, led to the establishment of the Scottish Oceanographical Laboratory in 1906.
The Davis Submerged Escape Apparatus, was an early type of oxygen rebreather invented in 1910 by Sir Robert Davis, head of Siebe Gorman and Co. Ltd., inspired by the earlier Fleuss system, and adopted by the Royal Navy after further development by Davis in 1927. While intended primarily as an emergency escape apparatus for submarine crews, it was soon also used for diving, being a handy shallow water diving apparatus with a thirty-minute endurance, and as an industrial breathing set.
John Walter Gregory,, was a British geologist and explorer, known principally for his work on glacial geology and on the geography and geology of Australia and East Africa.
The Heroic Age of Antarctic Exploration was an era in the exploration of the continent of Antarctica which began at the end of the 19th century, and ended after the First World War; the Shackleton–Rowett Expedition of 1921–1922 is often cited by historians as the dividing line between the "Heroic" and "Mechanical" ages.
Franklin's lost expedition was a failed British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror, and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better understanding could aid navigation. The expedition met with disaster after both ships and their crews, a total of 129 officers and men, became icebound in Victoria Strait near King William Island in what is today the Canadian territory of Nunavut. After being icebound for more than a year Erebus and Terror were abandoned in April 1848, by which point Franklin and nearly two dozen others had died. The survivors, now led by Franklin's second-in-command, Francis Crozier, and Erebus's captain, James Fitzjames, set out for the Canadian mainland and disappeared, presumably having perished.
The history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral, By classical Greek and Roman times commercial applications such as sponge diving and marine salvage were established, Military diving also has a long history, going back at least as far as the Peloponnesian War, with recreational and sporting applications being a recent development. Technological development in ambient pressure diving started with stone weights (skandalopetra) for fast descent. In the 16th and 17th centuries diving bells became functionally useful when a renewable supply of air could be provided to the diver at depth, and progressed to surface supplied diving helmets—in effect miniature diving bells covering the diver's head and supplied with compressed air by manually operated pumps—which were improved by attaching a waterproof suit to the helmet and in the early 19th century became the standard diving dress.
