This formula holds for the general case in which the base is a trapezium; the wedge being thus formed by cutting a triangular prism by any two planes.
His suggestion to print from type made wedge-shaped (that is, smaller at the foot and wider at the top) to allow of its being so fixed on a cylinder that it would radiate from the centre and thus present an even printing surface, was adopted later by Applegath and others, and really was the first conception of printing on the rotary principle which has now been brought to such perfection.

These are preferably made slightly wedge-shape, to avoid the inconvenience resulting from multiple internal reflections, and they must necessarily be rather thin, so that double refractions due to internal strain may not exert a disturbing influence.
In Prussia, with its traditional loyalty and its old-world caste divisions, he believed that such a conception could be realized, and he took up an attitude half-way between those who would have rejected the proposal for a central diet altogether as a dangerous "thin end of the wedge," and those who would have approximated it more to the modern conception of a parliament.
On the other hand, if he struck straight at Charleroi - the allied junction point - he would drive the "Armee du Nord" like an armoured wedge between the allies, if only he caught them unsuspicious and unready.
Such gums are formed abundantly in pycnidia, and, absorbing water, swell and carry out the spores in long tendrils, which emerge for days and dry as they reach the air, the glued spores gradually being set free by rain, wind, &c. In oidial chains (Sclerotinia) a minute double wedge of wall-substance arises in the middle lamella between each pair of contiguous oidia, and by its enlargement splits the separating lamella.
The first caused him to reject the idea of a conference of which the activities would have been primarily directed against Russia; the second led him to drive a wedge into the AngloFrench entente by making direct overtures to Great Britain.
In some Pteridophyte stems the apical eel is wedge-shaped, in others prismatic; in the latter case segment~
Of the wedge of immersion and emersion, will be the C.P. with respect to FF' of the two parts of the water-line area, so that b 1 b 2 will be conjugate to FF' with respect to the momental ellipse at F.
Mouthpiece, or of the flow of water through the arches of a bridge, with wedge-shaped piers to divide the stream.
', In Bobyleff's problem of the wedge of finite breadth, ch nS2 = ?a b' s h n S 2 = V b a a 1 u u b, (6)?
There was, for instance, Mendovg (1240-1263), who submitted to baptism for purely political reasons, checkmated the Teutonic Knights by adroitly seeking the protection of the Holy See, and annexed the principality of Plock to his ever-widening grand duchy, which already included Black Russia, and formed a huge wedge extending southwards from Courland, thus separating Poland from Russia.
Ross's or the roseate gull, Rhodostethia rosea, forms a well-marked genus, distinguished not so much by the pink tint of its plumage (for that is found in other species) but by its small dove-like bill and wedge-shaped tail.
An inclined piece of wedge-shaped steel, called the chill, to become perpendicular; in so doing the platen is forced down, and the impression takes place at the moment the chill is brought into a vertical position.
The outline of the state is that of a roughly-shaped wedge with the thin edge extending northward between and up to the junction of the rivers Araguaya and Upper Tocantins, and its length is nearly 15° of latitude.
Its name ("wedge") is due to its position on a hill between two streams, the Stura and the Gesso, with fine views of the mountains.
South-eastern Mongolia is the part of Mongolia which lies on the eastern slope of the Great Khingan Mountains, entering like a wedge between the lower course of the Nonni river and the middle Sungari.
Thus with a' =o, a stream is split symmetrically by a wedge of angle ' zr/n as in Bobyleff's problem; and, by making a = oo, the wedge extends to infinity; then chnS2= u, sh nS2= b n u.
Fortunately it chanced that another people, the Persians, had adopted the Assyrian wedge-shaped stroke as the foundation of a written character, but making that analysis of which the Assyrians had fallen short, had borrowed only so many characters as were necessary to represent the alphabetical sounds.
A peculiarly wedge-shaped snout, and toes provided with strong fringes, enable this animal to burrow rapidly in and under the sand of the desert.
The cathammal areas may remain very small, mere wedge-shaped partitions dividing up the coelenteron into a four-lobed stomach, the lobes of which communicate at the periphery of the body by a spacious ring-canal.
In studying the dispersion of the aniline dyes, a prism with a very small refracting angle is made of two glass plates slightly inclined to each other and enclosing a very thin wedge of the dye, which is either melted between the plates, or is in the form of a solution retained in position by surface-tension.
For four days the Austrians attacked, making a last effort on June 18, when 20 battalions were sent in against the Lemerle - Magnaboschi line in an attempt to drive a wedge between the Italian 30th and 33rd Divisions.
Wide, which appear to be a submerged part of the great central valley of Chile, and farther south by the narrower Moraleda channel, which terminates southward in a confusing network of passages between the mainland and the islands of the Chonos group. One of the narrow parts of the Chilean mainland is to be found opposite the upper islands of this group, where the accidental juxtaposition of Magdalena island, which indents the continent over half a degree at this point, and the basin of Lake Fontana, which gives the Argentine boundary a sharp wedge-shaped projection westward, narrows the distance between the two to about 26 m.
Secondly, to the west of this mountain wilderness, stretching upwards from the sea in a wedge form between the Brahui highlands and the group of towering peaks which enclose the Hingol river and abut on the sea at Malan, are the alluvial flats and delta of the Purali, forming the little province of Las Bela, the home of the Las Rajput.
The leaves are composed of seven radiating leaflets (long-wedge-shaped); when young they are downy and drooping.
Borelli was of opinion that flight resulted from the application of an inclined plane, which beats the air, and which has a wedge b action.
He, in fact, endeavours to prove that a bird wedges itself forward upon the air by the perpendicular vibration of its wings, the wings during their action forming a wedge, the base of which (c b e) is directed towards the head of the bird, the apex (a f) being directed towards the tail (d).
The same argument is re stated in different words as under: - " If the air under the wings be struck by the flexible portions of the wings (flabella, literally fly flaps or small fans) with a motion perpendicular to the horizon, the sails (vela) and flexible portions of the wings (flabella) will yield in an upward direction and form a wedge, the point of which is directed towards the tail.
