He was educated partly in Holland and then under Franciscus Zypæus (the younger) at Louvain, and in Paris. On 13 September 1667 he was entered as a medical student at Leyden, but graduated M.D. at Utrecht on 18 March 1670. His thesis, ''De Calculo Vesicæ'' (Utrecht, 1670), was translated into English and published in London in 1677, and with large additions in 1710. About 1673 he was appointed physician in chief to the garrison at Grave. Ten years afterwards he came to England, settled in Throgmorton Street, London, and was admitted a licentiate of the Royal College of Physicians on 2 April 1683. Charges of malpractice Supported by powerful patronage he passed as a specialist on gout and stone, but was regarded by most of his brethren as a quack. In 1693 he was summoned before the college for mala praxis in the internal ...

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Cantharidin
Cantharidin is an odorless, colorless fatty substance of the terpenoid class, which is secreted by many species of blister beetles. It is a burn agent or a poison in large doses, but preparations containing it were historically used as aphrodisiacs (Spanish fly). In its natural form, cantharidin is secreted by the male blister beetle and given to the female as a copulatory gift during mating. Afterwards, the female beetle covers her eggs with it as a defense against predators. Poisoning from cantharidin is a significant veterinary concern, especially in horses, but it can also be poisonous to humans if taken internally (where the source is usually experimental self-exposure). Externally, cantharidin is a potent vesicant (blistering agent), exposure to which can cause severe chemical burns. Properly dosed and applied, the same properties have also been used therapeutically, for instance for treatment of skin conditions such as molluscum contagiosum infection of the skin. Cantharidi ...

17th-century English Medical Doctors
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily k ...

Narcissus Luttrell
Narcissus Luttrell (1657–1732) was an English historian, diarist, and bibliographer, and briefly Member of Parliament for two different Cornish boroughs. His ''Brief Historical Relation of State Affairs from September 1678 to April 1714'', a chronicle of the Parliaments of England and Great Britain, was distilled from his diary and published in 1857, after Macaulay had drawn attention to the manuscript in All Souls College, Oxford. Although Luttrell was for most of his life a private citizen and relied primarily on secondary sources for the workings of Parliament, he is often the best source available for legal and political matters of the time. The legislation itself is covered by the official parliamentary journals, but Luttrell's diary is often the only record of debates within the Palace of Westminster. As a result, Luttrell provides crucial political information which cannot be found elsewhere; as one example out of many, he notes that the debate on taxation of 1691 was d ...

Newgate Prison
Newgate Prison was a prison at the corner of Newgate Street and Old Bailey Street just inside the City of London, England, originally at the site of Newgate, a gate in the Roman London Wall. Built in the 12th century and demolished in 1904, the prison was extended and rebuilt many times, and remained in use for over 700 years, from 1188 to 1902. For much of its history, a succession of criminal courtrooms were attached to the prison, commonly referred to as the "Old Bailey". The present Old Bailey (officially, Central Criminal Court) now occupies much of the site of the prison. In the late 1700s, executions by hanging were moved here from the Tyburn gallows. These took place on the public street in front of the prison, drawing crowds until 1868, when they were moved into the prison. History In the early 12th century, Henry II instituted legal reforms that gave the Crown more control over the administration of justice. As part of his Assize of Clarendon of 1166, he requi ...
