HARTSHORN. The name given in pharmacy to the antlers of the Cervus elaphus. Its com- position is very difi'erent from that of persistent horns, as those of the ox. for example, and is identical, or nearly so, with that of bone. The products of its distillation were formerly much used in medicine, under the titles of oil of harts- horn, volatile salt of hartshorn, spirits of harts- horn, etc. ; but they are now replaced by simpler preparations of the active ingredients of these substances, namely, ammonia and carbonate of ammonia.

HARTSOEKER, hiirt'soo-ker. Niklaas ( 1656- 1725). A Dutch physicist and histologist, born at Gouda. He early showed a taste for mathe- matics and physics; studied these subjects with- out the permission or knowledge of his father, a Reformed clergj'man. who wished his son to become a clergyman : and at the age of eighteen made a powerful microscope, with which he made striking discoveries regarding spermatozoa. His father finally consented to his going to Leyden. and later to Amsterdam, where he met Huy- gens, and confided to him his discoveries. In 1678 he went to Paris and studied under Cas- sini ; from 1684 to 1696 he lived in Paris, and then returned to Holland to become the in- structor of Peter the Great. He went to Diis- seldorf, in 1704. on the urgent invitation of the Elector of the Palatinate, and was appointed honorary professor at Heidelberg. In 1717. after the Elector's death, he moved to Utrecht, where his continued application to work broke his health. His works include: Essai de diop- triqne (1694). in which his independent discov- ery of many of Newton's observations on light appeared, as well as a well-defined theory of general physics; Principes de physique (1696), developing this theory: Conjeetiires physiques (1707-OSJ ; and Coursde physique (1730).
