EYE. 400 EYLAU. stone, etc., are driven into the interior of the eye, there is great danger of destructive inflam- mation and sympathetic ophthalmia. (See Oph- thalmia.) Most commonly foreign bodies, as particles of dust, sand, seeds, flies, etc., merely get into the space between the eyeball and the lids, almost always concealed under the upper, as it is the larger, and sweeps the eye. They ca pain, from the firmness and sensitiveness of the papillary surface of the lid, soon excite inflam- mation, and their presence as the cause is apt to be overlooked. The lid must be turned over to find them. To do this, pull the front or edge of the lid forward by the eyelashes, held with the finger and thumb, and at the same time ] ress down the back part of the lid with the tip of the left forefinger, or with a small pencil or kei . The lid will readily turn over, when the body may be seen and removed with the corner of a handker- chief. In other cases, a solution of cocaine must be instilled and a needle used to dislodge the particle. After the bodies are removed, a feeling as if they were still there may remain for some time.

The extreme forward part of a ship is called the eyes of the ship. Chinese junks and other native craft have blocks of wood shaped and painted to resemble human eyes placed on each side of the bow, and the hawse-holes of ships of Europe and America are sometimes compared to eyes, and may at one time have been so called. The eyes of the rigging are loops formed in the shrouds or stays for fitting around the mastheads. A deadeye is a block of hard wood (usually lignum vita?) pierced with several holes. Two deadeyes are made to form a sort of tackle by reeving a rope through them; in rigged ships of old type the lower ends of shrouds and stays were secured to such tackles, which were kept in place permanently. An eye-holt is a bolt that has a projecting end formed in the shape of a ring for the purpose of hooking a tackle or at- taching a rope. Eyelets, or eylet-holes, are small circular holes in sails, awnings, etc., through which |i:is small ropes. An eye-splice is an eye formed at the end of a rope by separating the strands at the end and sticking (hem between the strands in a special manner at the proper place. EYE, IV Ai i i ST "- (1825-96).

EYE OF GKEECE. An ancient epithet of Athens. EYEPIECE, or OoULAB. The name given to the lens or tenses by means of which the in of tin- object formed ai th of a tel pe or microscope is observed. See Telescope, and Microscope. '1 here are two forms of eyepieces in general use, each of which possesses advantages for certain classes of work. In the Ramsden eyepiece there are two plano-convex lenses of equal focus placed with their curved sides toward each other. As the image is formed beyond the lenses this eye- piece can be used in micrometer miseroscopes. ( See Micrometers.) In the Huyghenian ej epiece there are two plano-convex lenses, the lower of which has a focal length several times grei than that of the upper. The curved face of the upper lens faces toward the plane face of the lower, and the image is formed between the two. ii-eountof the eyepieces used in microscopes will be found in Carpenter, The Microscope (8th ed., Philadelphia, 1001). EYERMAN, i'er-man, John (1867—). An American geologist and genealogical writer. He was born at Easton. Pa., of Pennsylvanian Dutch -i iv. was educated at Lafayette College, and continued his studies at Harvard, Columbia, and Princeton universities.
