Wallich, George Charles

WALLICH, GEORGE CHARLES

(b. Calcutta, India, November 1815; d. Marylebone, London, England, 31 March 1899), medicine, zoology.

Wallich was the eldest son of Nathaniel Wallich, superintendent of the botanical gardens at Calcutta from 1815 to 1850. He was sent to Beverley (Yorkshire) and, later, to Reading Grammar School. After attending the arts classes at King’s College, Aberdeen, he received an M. D. at Edinburgh University in 1836. Ironically, a classmate was Edward Forbes, proponent of the azoic theory, which held that the absolute depth to which life extended in the seas was 300 fathoms.

Wallich entered the Indian army in 1838, served in the Sutlej (1842) and Punjab (1847) campaigns with distinction, and was field surgeon during the Sonthal rebellion (1855 – 1856). He was invalided to England in 1857 and spent two years recuperating on Guernsey before settling in Kensington.

In 1860 Wallich shipped as naturalist on H.M.S. Bulldog, under the command of Sir Francis Leopold McClintock, to survey the proposed north Atlantic telegraph route between Great Britain and America (2 July – 11 November). A single sounding during October in 1,260 fathoms (lat. 59° 27’N., long. 26°41’W.) brought up thirteen living starfishes (Ophiocomae) from the bottom—incontrovertible, although at the time generally disregarded, evidence that “The conditions prevailing at great depths …are not incompatible with the maintenance of animal life” as well as “…the inference that the deep sea has its own special fauna.” Although he wrote extensively on this discovery, the majority of Wallich’s scientific publications dealt with the Protozoa. He entered the Bathybius controversy with trenchancy, correctly opposing Huxley, who in the course of examining a ten-year-old collection of sea-bottom samples, found a gelatinous substance that he took to be a primitive form of life and named after Ernst Haeckel. The substance was later determined by J. Y. Buchanan to be a precipitate of calcium sulfate caused by the alcohol in which the samples were preserved.

The year before his death, Wallich was awarded the gold medal of the Linnean Society of London “in recognition of his researches into the problems connected with bathybial and pelagic life.”

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
