Genus and species names are always italicized when printed; the names of other taxa (families, etc.) are not. When a species (or several species of the same genus) is mentioned repeatedly, the genus may be abbreviated after its first mention, as in Q. alba.inomial Nomenclature. The present system of binomial nomenclature identifies each species by a scientific name of two words, Latin in form and usually derived from Greek or Latin roots.
ORDINANCE. A law, a statute, a decree. An ordinance is a law enacted by a municipal body, such as a city council or county commission (sometimes called county council or county board of supervisors). Ordinances govern matters not already covered by state or federal laws such as zoning, safety and building regulations. This word is more usually applied to the laws of a corporation than to the acts of the legislature; as the ordinances of the city of Philadelphia.
The Northwest Ordinance (formally An Ordinance for the Government of the Territory of the United States, North-West of the River Ohio, and also known as the Freedom Ordinance or The Ordinance of 1787) was an act of the Congress of the Confederation of the United States (the Confederation Congress), passed July 13, 1787.he 1787 law relied on a strong central government, which was assured under the new Constitution that took effect in 1789. In August, 1789, it was replaced by the Northwest Ordinance of 1789, in which the new Congress reaffirmed the Ordinance with slight modifications.
