*KOLLIKER, ALBERT, a distinguished living physiologist, more especially known for his researches with the microscope. He was born in Germany, and is at present professor of anatomy and physiology in the university of 1Vurzberg. Kolliker is one of the younger phy siologists who has commenced his career since the more extended use of the microscope, and he has distinguished himself by the masterly manner in which he has applied this instrument to the unravelling the intricate textures of the human and animal body. One of his earliest papers appeared in Valentine's 'Repertorium' for 1841, on the repro ductivo organs and fluid of invertebrate animals. In 1842 he pub lished a thesis on the origin of the ovum in insects, and a comparison between the development of this organ in the articulate animals and the Vertebrata. In 1844 he published at Zurich a paper on the development of the Cephalopoda, and in 1846 a paper on the contractile cells of the embryo of Planaria. These and other labours on the minute structure of animals prepared him for a greater work ou the Microscopic Anatomy, or Histology of the Human Body. The first volume of
this work was published in two parte in 1850 and 1S52, and consisted of a detailed account of his own and others' iovestigatiou of the tissues of the human body. This work was however too extensive for the use of the medical student, and in 1852 he published a complete work entitled 'Handbuch der Gewebelehre des .Menschen,' in one volume with 343 woodcuts. This work was translated into the English lan guage by Messrs. Busk and Huxley, and published in two volumes by I the Sydenham Society. It contained a large amount of original investigation, and has deservedly placed Professor Kolliker at the head of the modern school of histologi-Its. Since the publication of this work he has published many papers on the minute structure of the lower animals. He has been several times in England, and was present at the meetiug of the British Association held in Glasgow in the year 1855.
