Antoine François Alfred Lacroix
Antoine François Alfred Lacroix (4 February 186312 March 1948), known as Alfred Lacroix, was a French mineralogist and geologist. He was born in Mâcon, Saône-et-Loire. Education Alfred Lacroix completed a D. s Sc. in Paris in 1889, as student of Ferdinand André Fouqué. Fouqué only agreed to the graduation if Lacroix would marry his daughter. Career In 1893, Alfred Lacroix was appointed professor of mineralogy at the Jardin des Plantes, Paris, and in 1896 director of the mineralogical laboratory in the École des Hautes Études. He paid especial attention to minerals connected with volcanic phenomena and igneous rocks, to the effects of metamorphism, and to mineral veins, in various parts of the world, notably in the Pyrenees. In his numerous contributions to scientific journals he dealt with the mineralogy and petrology of Madagascar, and published an elaborate and exhaustive volume on the eruptions in Martinique, ''La Montagne Pelée et ses éruptions'' (Paris 1904). ...

Mâcon
Mâcon (), historically Anglicization, anglicised as Mascon, is a city in east-central France.

Mâcon is the southernmost city in the department of Saône-et-Loire and the region of Bourgogne-Franche-Comté. It is north of Lyon and from Paris. The climate is temperate with a slight continental tendency. Climate Mâcon features an oceanic climate (Köppen climate classification, Köppen: ''Cfb''), with warm summers, slightly too cool to be called humid subtropical climate, humid subtropical (''Cfa'').

Metamorphism
Metamorphism is the transformation of existing Rock (geology), rock (the protolith) to rock with a different mineral composition or Texture (geology), texture. Metamorphism takes place at temperatures in excess of , and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Metamorphism is distinct from weathering or diagenesis, which are changes that take place at or just beneath Earth's surface. Various forms of metamorphism exist, including Regional metamorphism, regional, Contact metamorphism, contact, Hydrothermal metamorphism, hydrothermal, Shock metamorphism, shock, and Dynamic metamorphism, dynamic metamorphism. These differ in the characteristic temperatures, pressures, and rate at which they take place and in the extent to which reactive fluids are involved. Metamorphism occurring at increasing pressure and temperature conditions is known as ''prograde metamorphism'', while decreasin ...

Oligodon
''Oligodon'' is Genus (biology), genus of Colubridae, colubrid snakes that was first described by Austrian people, Austrian zoologist Leopold Fitzinger in 1826. This genus is widespread throughout Central Asia, central and tropical Asia. The snakes of this genus are Common name, commonly known as kukri snakes. Description The species in the genus ''Oligodon'' are egg eaters and are usually under 90 cm (35 in) in total length (including tail). Different species display widely variable patterns and colorations. They subsist mostly by scavenger, scavenging the egg (biology), eggs of birds and reptiles. Besides eggs, species of this genus also feeds on lizards, frogs, and small rodents. ''Oligodon'' is a rear-fanged snake genus. All member species have a set of enlarged teeth placed in the back of the upper jaws, as well as functional Duvernoy's glands. They are not dangerous to humans, though. Bites by some species have been reported to bleed excessively, suggesting pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cimetière Du Montparnasse
Montparnasse Cemetery () is a cemetery in the Montparnasse quarter of Paris, in the city's 14th arrondissement. The cemetery is roughly 47 acres and is the second largest cemetery in Paris.

Académie Des Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationale, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the academy's existence were relatively informal, since no statutes had as yet been laid down for the ins ...
