certain days set apart for prayer and fasting, one special theme of supplication being that the blessing of God may descend on the crops, and consequently that there may be plenty in the land. Stated days of this character began to be observed in the 3d century, but at first there was no unity over the Christian world as to the precise days. In A. D. 1095 the Council of Placentia diffused them over the year.

that department of biology which traces the development of the individual organism before birth. It gives the history of the organism from its earliest individual appearance till it is born or hatched, properly including all the anatomical and physiological changes that take place in the embryo, whether in the uterus or the egg. The investigation necessarily takes two forms; a description of the successive structural stages, and an analysis of the vital processes associated with each step. The development of the chick was watched in Greece 2,000 years ago by Aristotle and Galen; and in 1651 Harvey sought to establish two main propositions: (1) that every animal was produced from an ovum, and (2) that the organs arose by new formation (epigenesis), not from the expansion of some invisible preformation. But as a systematic science embryology dates from the 19th century. Wolff in 1759 reasserted Harvey's epigenesis, and showed that the germ consisted of almost structureless material, and that the process of development was a gradual organization. In 1817 Pander took up Wolff's work virtually where he left it. He was immediately re-enforced and soon left behind by Von Baer, whose investigations laid a firm foundation for modern embryology. Since the establishment of the cell-theory in 1838-1839, and the now well-known facts that the organism starts from a fusion of two sex-cells, and that development consists in the division of the fertilized ovum and differentiation of the results, progress has been rapid.

an epithet applied to Ireland, from the freshness and bright of the verdure, color produced by the abundant heat and moisture continually reaching it from the Atlantic. This epithet was first used by Dr. W. Drennan (1754-1820), in his poem entitled "Erin."

See Countersinks. Emery Files, Pencils and Sticks. Emery files are to be had ready made from all material dealers and consist of wooden handles to which emery cloth is glued. Emery pencils are kept by some dealers and will be found very useful for grinding the inside of metal objects, and also on small work of various kinds, being easy to handle, clean and light. Emery sticks are of two kinds, solid square sticks and round and square sticks of wood to which emery paper or cloth is glued. Emery paper and cloth may be had from most material dealers, varying from 0000 to No. 4.

Wheels of solid emery or wooden wheels, to the surface of which emery paste has been applied. The best wheels for watchmakers' use are the solid wheels in which vulcanite is the cementing medium. They may be had from material dealers generally or from dental supply houses, in sizes varying from 1/2x1/8 in. to 3 1/2x3/4 in. A set of three or more of these wheels will prove very valuable adjuncts to the watchmaker's bench for grinding dials to allow freedom of motion for wheels in fitting new dials; for grinding milling cutters, drills, gravers, etc. As purchased from dealers these wheels have a central hole, by means of which they can be mounted for use by the watchmaker as follows: Turn down a piece of No. 30, Stubbs' steel wire, to the size of the opening in your wheel and rivet your wheel firmly upon it, as shown in Fig. 126. It can then be used in your lathe very handily, either with or without water. The best sizes for watchmakers use are 1/2 in., 1 in. and 1 1/2 in. diameter.
