There are nine recent subspecies of tiger, three of which are extinct, one of which is nearly certain to become extinct in the near future, and five of which still occur. Their chronological range ran through Russia, Siberia, Iran, Afghanistan, India, China and south-east Asia, including the Indonesian islands. These are the ongoing subspecies, in descending order of wild population: Bengal tiger
The Bengal tiger or the Royal Bengal tiger (Panthera tigris tigris) is originate in parts of India, Bangladesh, Nepal, Bhutan and Myanmar. It lives in different habitats: grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangroves. The Indian government's estimated populace figure for these tigers is between 3,100 and 4,500, some 3,000 of which are found in India alone. However, many Indian tiger conservationists uncertainty this number, seeing it as overly optimistic. The number of Bengal tigers in India may be less than 2,000, as most of the collected statistics are based on pugmark identification, which often gives a biased result.
Tiger's eye (also Tigers eye, Tiger eye) is a chatoyant gemstone that is generally yellow- to red-brown, with a silky luster. It is a rubbery silicified crocidolite (blue asbestos), a classic model of pseudomorphous replacement. An incompletely silicified blue option is called Hawk's eye. A member of the quartz group, its physical and optical properties are the same or very near to those of single-crystal quartz.
The gems are generally cut en cabochon in order to best display their chatoyancy. Red stones are brought about through calm heat treatment. Honey-coloured stones have been used to try to be like the much higher valued cat's eye chrysoberyl (cymophane), but the overall effect is unconvincing. Artificial fibreoptic glass is a general imitation of tiger's eye, and is produced in a wide range of colours.
The word "tiger" is taken from the Greek word "tigris", which itself is consequential "possibly from an Iranian source." In American English, "Tigress" was first record in 1611. "Tiger's-eye" is a name for a golden-brown with stripes, chatoyant, fibrous assortment of quartz used as a semi-precious gemstone. It was one of the lots of species formerly described, as Felis tigris, by Linnaeus in his 18th century work, Systema Naturae. The generic factor of its scientific designation, Panthera tigris, is often presumed to derive from Greek pan- ("all") and ther ("beast"), but this may be a folk etymology. Although it came into English from side to side the classical languages, panthera is probably of East Asian origin, meaning "the yellowish animal," or "whitish-yellow".
The tiger (Panthera tigris) is a animal of the Felidae family, the largest of four "huge cats" in the Panthera genus. Native to the mainland of Asia, the tiger is an top predator and the largest graceful species in the world, comparable in size to the biggest fossil felids. The Bengal Tiger is the most common subspecies of tiger, constituting something like 80% of the entire tiger population, and is found in India, Bangladesh, Bhutan, Myanmar and Nepal. It has disappeared from much of its previous circulation including the Caucasus, Java and Bali.
The tiger is an endangered variety, with the majority of the world's tigers now living in captivity.Several subspecies are extinct and others critically in danger of extinction. Tigers have featured in ancient mythologies and tradition, and continue to be depicted in modern films and literature, as well as appearing on flags, coats of arms and as mascots for sporting teams. It is the national animal of India, among other countries.
A postal marking is any kind of marginal note applied to a letter by a postal service. The most frequent types are postmarks and cancellations; almost every letter will have those, less common types include forward addresses, routing annotations, warnings, postage due notices and explanations, such as for smashed or delayed mail. A key part of postal history is the credit of postal markings, their purpose, and period of use.
Service marks give in sequence to the sender, recipient, or another post office. Advice marks notify about forwarding, miss ending, letters received in bad condition, letters received too late for delivery by a certain time, or the reason for a delay in mail delivery. Dead letter offices would use a variety of markings to keep track of their progress in finding the addressee, such as a notation that the letter had been advertise in the local newspaper. The tracking process for register mail may entail many marks and notations.
Shortly after the eruption of the American Civil War, the Northern authorities affirmed the existing postage stamps invalid and issued new types. Letters using the demonetized stamps received a marking "OLD STAMPS NOT RECOGNIZED", an accidentally humorous comment much prized by collectors today.
