This is a rare and desirable 1876 Challenger Expedition Sea Sounding Microscope Slide from 21st March, 1876 (station 338, near Saint Helena in Atlantic Ocean)------ Challenger Expedition globigerina ooze microscope slide at 1990 fathoms. The Challenger expedition of 1872-76 was a scientific exercise that made many discoveries to lay the foundation of oceanography. The expedition was named after the mother vessel, HMS Challenger. Prompted by Charles Wyville Thomson of the University of Edinburgh and Merchiston Castle School the Royal Society of London obtained the use of Challenger from the Royal Navy and in 1872 modified the ship for scientific work, equipping her with separate laboratories for natural history and chemistry. The expedition, led by Captain George Nares, sailed from Portsmouth, England, on 21 December 1872. She traveled nearly 70,000 nautical miles (130,000 km) surveying and exploring. The result was the Report Of The Scientific Results of the Exploring Voyage of H.M.S. Challenger during the years 1873-76 which, among many other discoveries, cataloged over 4,000 previously unknown species. John Murray, who supervised the publication, described the report as "the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries" Findings from the Challenger expedition continued to be published until 1895, 19 years after the completion of its journey. The report contained 50 volumes and was over 29,500 pages in length. Specimens brought back by the Challenger were distributed to the world's foremost experts for examination, which greatly increased the expenses and time required to finalize the report. The report and specimens are currently held at the British Natural History Museum and the report has been made available online. Some specimens, many of which were the first discovered of their kind, are still examined by scientists today.
