ASSAULT, in English law, "an attempt or offer with force or violence to do corporal hurt to another, as by striking at another with a stick or other weapon, or without a weapon, though the party misses his aim." Mere words, be they ever so provoking, will not constitute an assault. Coupled with the attempt or threat to inflict corporal injury, there must in all cases be the possibility of carrying the threat into effect, and so if the person threatened is out of range there can be no assault. A battery is more than a threat or attempt to injure the person of another; the injury must have been inflicted, but it makes no difference however small it may be, as the law does not "draw the line between degrees of violence," but "totally prohibits the first and lowest stage of it." Every battery includes an assault. A common assault is a misdemeanour, and is punishable by imprisonment with or with out hard labour to the extent of one year, or by fine, and if it occasions bodily harm, with penal servitude for five years, or imprisonment to the extent of two years, with or without hard labour. There are various different kinds of assaults of a more serious description which are provided against by particular enact ments of parliament, such as the Offences against the Person Act 1861 ; and there are also certain aggravated assaults for which the punishment is more severe than for common assault, as an assault with intent to murder, with intent to commit a rape, etc. An assault may be both a tort and a crime, giving a civil action for damages to the person injured, as well as being the subject of a criminal prosecution.
In military language, the word is used of the culminating phase of an attack, when the advancing troops come to close quarters with the enemy, surging into and overrunning his positions. ASSAYE, a village of Hyderabad or the Nizam's Dominions, in southern India, just beyond the Berar frontier. The place is celebrated as the site of a battle fought on Sept. 23, 1803, between the combined Mahratta forces under Sindhia and the rajah of Berar and the British under Maj.-Gen. Wellesley, afterwards the duke of Wellington. The Mahratta force consisted of so,000 men, supported by loo pieces of cannon served by French artillery men, and entrenched in a strong position. Against this the Eng lish had but a force of 4,500 men, which, however, after a severe struggle, gained the most complete victory that ever crowned British valour in India. Of the enemy 12,000 were killed and wounded; and Gen. Wellesley lost 1,657—one-third of his little force—killed and wounded. Assaye is 261m. N. W. of Hyderabad. ASSAYING, a term originally applied to the trying or test ing of ores and alloys for their contents of gold or silver. Later it has received a wider significance; from meaning to test any ore or metallurgical product, in order to find its proportion of valuable constituents, it has even been extended to cover the determination of alkaloids (q.v.) in plants. It will, however, be used in this article in a metallurgical sense only. It is essentially a commercial process, hence the difference between assaying and chemical analysis. Analysis is an end in itself : the greater the accuracy, the more satisfactory is the result. In assaying it is desired to determine the value of a material, and a degree of accuracy which exceeds that required to obtain this value is uneconomical for it requires excessive time and care which might be more valuably employed. This does not mean that great accuracy is never required, as the value of the substance to be determined must be taken into account. For example, in the assay of ores, iron is usually reported to o.1%, whereas platinum may be carried beyond an accuracy of o.000i%.
The origin of the art is lost in antiquity. The trial by "Touch stone" and by "Fire" are mentioned by Theophrastus (371 288 B.c. ), and the early alchemists were well acquainted with such processes as precipitation, cupellation, etc., which are still in everyday use. The earliest known books on assaying were published in Germany at the beginning of the 16th century. The most interesting of these is Agricola's De Re Metallica, which devotes considerable space to the subject.
Assaying is closely allied to the metallurgical industry. In early times it was merely a small-scale smelting operation, and followed the large-scale processes in detail. Hence the "Dry" or "Fire" assays originated, in which the assay sample was smelted in a small crucible with suitable reagents, using a wood or charcoal furnace. The simultaneous development of chemistry led to the introduction of analytical or "Wet" methods, which are now used for the majority of metals. The old smelting, or "Fire" assay, has survived for some materials, and is still the only method available for the determination of gold and silver in ores.
The trial by "Touchstone," or "Lydian stone," to estimate the gold proportion of alloys, probably dates from the time of the Lydians (500 B.e.) . The colour of the streak made on a black stone by the metal under examination, was compared with similar streaks made by "needles" of metal of known composition, called "Touchneedles." These needles were used in sets, one of golden-silver alloys, another of gold-copper alloys, and a third of "Triple" alloys, containing gold, silver, and copper. Touch needles were introduced later for testing silver-copper alloys.
