- Nitrogen (Wikipedia)
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth’s atmosphere, making it the most abundant uncombined element in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.
- I became well satisfied with my new station; there was plenty to eat and little to do, and pleasant surroundings. I was appointed adjutant and had to look after the guard and the bakehouse and the drilling of the company. Capt. Jones continued in command;6 Lieut. Slaughter was quartermaster and commissary, and Mrs. Slaughter, who was the only lady at the post, managed the mess, where we all took our meals. Dr. Haden was the Post Surgeon; he had ridden to meet us before our arrival. He was a courteous and refined Southerner, of blonde complexion and affable manners, and not obtrusive in his southern sentiments. There was also a Dr. Wallace, brother of Capt. Wallace, of the Fourth Infantry, who desired to become post sutler.
