Histologist

One learned in histology. Histology, n. [Gr. histos, a web, logos, a discourse.] A term identical, or almost so, with general minute anatomy, or microscopic anatomy. H. cla ifies and describes the structural or morphological elements which exist in the solid and fluid parts of organic bodies. This science did not make any great progre until the commencement of the nineteenth century, when the invention of the compound microscope caused its advancement. Its origin, however, may be traced back to Malpighi, who lived in the seventeenth century, and discovered the blood-corpuscles. In more recent times, very valuable discoveries have been made by uniting the use of the microscope to experimental chemistry. The structure of different horny ti ues was thus first shown; and it was proved that whalebone, nails, and cow-horn are similarly composed of aggregations of diminutive cells. H. has also been useful in the investigation of the nervous ti ues, and of many other structures, and has been a very important element in the recent development of medical science. Much useful information has also been obtained through the study of vegetable H. Kölliker, Leydig, Frey, and Schwann, may be mentioned among those who have practiced it succe fully in Germany: Robin and Lebert in France; and in England, Todd, Bowman, Clarke, Beale, Queckett, Bennett, and Lockhart, while the histologists of the U. S. are now among the foremost in the world.
