Beating the bounds (called in Scotland riding the marches) was a popular English ceremony of perambulation round the boundaries of a township or parish on Ascension Day with the view of keeping alive the memory of the places where the boundaries ran. It used to be sometimes customary to whip the boys of the parish school at important spots during the walk, and this practice continued at some places up to the start of the 20th century.

Holy Thursday, or Ascension-day, in the Anglican Church, is a movable feast, always falling on the Thursday but one before Whitsuntide. In the East Catholic Church, Holy Thurdsay is the Thursday in Holy Week. Research Holy Thursday
In astronomy, the right ascension is the distance of a star or other heavenly body from the first point of Aries, or the point of intersection of the sun's path with the celestial equator. The right ascension, together with the declination of a star, fixes its position. Right ascension is stated in hours and minutes, fifteen degrees being equal to one hour. Research Right Ascension
Correggio was the name taken by Antonio Allegri from his birthplace near Modena. He was an Italian painter and was born in 1494 at Corregio and died in 1534. Little is known of his life, which was very retired. Almost the only anecdote told of him is that on seeing the St Cecilia of Raphael he exclaimed 'Anch 'io son pittore' (I also am a painter), but thia is doubtful. Correggio is unrivalled in chiaroscuro and in the grace and rounding of his figures. Among his best pictures are Night, in which the chief light is the glory beaming from the infant Saviour; the St Jerome; the Marriage of St Catherine; several Madonnas, one of them (called La Zingarella, or the Gipsy Girl) said to represent his wife; the Penitent Magdalene; the altar-pieces of St Francis, St George, and St Sebastian; Christ in the Garden of Olives; the fresco of the Ascension in the Church of St John, Parma; the Assumption of the Virgin in the cathedral of the same city; the Ecce Homo, and Cupid, Mercury, and Venus, both in the National Gallery, London.

Henry V was Emperor of Germany. He was born in 1081 and died in 1125. The the son and successor of Henry IV of Germany, on his ascension the question of investiture distracted the empire anew. PopePascal would only confer the imperial crown upon condition that the rights claimed by Gregory should be formally conceded. Henry therefore seized the pope at the altar, and imprisoned him until he yielded two months later, and crowned Henry in April 1121.
Disturbances, however, arose in Germany, especially with Lothaire of Saxony, and the pope, declaring that his peace with the emperor had been compulsory, formented the strife. The war continued two years, and devastated Germany, and after a second expedition to Italy and excommunication by successive popes, Henry was compelled to yield in the matter of investiture, and in 1122 subscribed the Concordat of Worms. Henry was the last of the Salic or Frankish family of emperors, which was succeeded by the Suabian house. He married Matilda, a daughter of Henry I of England. Research Henry V of Germany
Capillarity is the general name for certain phenomena exhibited by fluid surfaces when the vessels containing the liquid are very narrow, and also exhibited by that portion of the fluid surface which is in close proximity to the sides of a larger vessel, or to any inserted object.
Thus if an open tube of small bore be inserted in water, it will be noted that the liquid rises within it above its former level to a height varying inversely as the diameter of the bore, and that the surface of this column is more or less concave in form. The same phenomenon occurs in any fluid which will wet the tube; but in the case of a fluid like mercury, which does not wet the glass, the converse phenomenon appears, the liquid being depressed in the tube below its former level, and the portion within the tube exhibiting a convex surface.
Similarly round the sides of the respective vessels, and round the outsides of the inserted tubes, we find in the first case an ascension, and in the second a depression of the liquid, with a corresponding concavity or convexity at its extreme edge. Two parallel plates immersed in the liquids give kindred results. As these phenomena occur equally in air and in vacua they cannot be attributed to the action of the atmosphere, but depend upon molecular actions taking place between the particles of the liquid itself, and between the liquid and the solid, these actions being confined to a very thin layer forming the superficial boundary of the fluid.
Every liquid, in fact, behaves as if a thin film in a state of tension formed its external layer; and although the theory that such tension really exists in the superficial layer must be regarded as a scientific fiction, yet it adequately represents the effects of the real cause, whatever that may be. Scientific calculations with respect to capillary depressions and elevations proceed, therefore, on the working theory that the superficial film at the free surface is to be regarded as pressing the liquid inwards, or pulling it outwards according as the surface is convex or concave - the convex or concave film being known as the meniscus (crescent). The part which capillarity plays among natural phenomena is a very varied one. By it the fluids circulate in the porous tissues of animal bodies; the sap rises in plants, and moisture is absorbed from air and soil by the foliage and roots. For the same reason a sponge or lump of sugar, or a piece of blotting-paper soaks in moisture, the oil rises in the wick of a lamp, etc. Research Capillarity
