Dick was enraged to see how contentedly the men bore the irksome confinement, the meager food, and harsh peremptoriness of the beardless boys set over them as guards. Most of the prisoners passed the time in cards, playing for buttons, trinkets, or what not that formed their scanty possessions. Dick learned that all the commissioned officers of the company with Wesley Boone had been wounded or killed in the charge near the stone bridge. Wesley had been with the prisoners at first. He had been struck on the head, and was in a raging fever when his father and sister came to the prison to take him away. No one could tell where he was now, but Dick knew that he must be in the city, since there were no exchanges, the Confederates allowing no one to leave the lines except women with the dead, or those who came from the North on special permits. Then he visited the provost headquarters, and was shown the complete list of names recorded in the books there; but Barney's was not among them. At the Spottswood Hotel, the day after his coming, he met Elisha Boone, haggard, depressed, almost despairing. Dick had no love for the hard-headed plutocrat, but he couldn't resist making himself known.

Where did Dick visit after his stop at the provost headquarters?

Washington (CNN) -- The U.S. Food and Drug Administration announced Wednesday that laboratory tests on popular smoking devices known as electronic cigarettes have found they contain carcinogens and other toxic chemicals dangerous to humans. E-cigarettes are battery-operated and contain cartridges filled with nicotine and other chemicals. Known as "e-cigarettes," the devices are battery-operated and contain cartridges filled with nicotine and other chemicals, spiced with flavors such as chocolate, cola or bubble gum. While manufacturers tout e-cigarettes as a "healthy way" to smoke, federal health officials say the devices turn nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user. "The FDA is concerned about the safety of these products and how they are marketed to the public," said Dr. Margaret A. Hamburg, commissioner of the FDA. CNN contacted Florida-based Smoking Everywhere, one of the largest manufacturers of e-cigarettes, after the FDA announcement, and a spokeswoman said the company had no comment. Because e-cigarettes have not been submitted to the FDA for evaluation or approval, the agency had no way of knowing the levels of nicotine or the amounts or kinds of other chemicals that the various brands of these products deliver to the user. That is why the FDA began to test them. The FDA's Division of Pharmaceutical Analysis analyzed the ingredients in a small sample of cartridges from two leading brands of e-cigarettes. In releasing its information, the FDA did not identify the two companies, but said in one sample, diethylene glycol -- a chemical used in antifreeze that is toxic to humans -- was detected. Other samples detected carcinogens that are dangerous to those who smoke them, the FDA said. The FDA has been examining and seizing shipments of non-U.S.-made e-cigarettes at the U.S. border since summer 2008. To date, 50 shipments have been stopped. The products examined thus far meet the definition of a combination drug-device product under the Federal Food, Drug, and Cosmetic Act. "We know very little about these devices, said Dr. Jonathan Samet, director of the Institute for Global Health at the University of Southern California, "but to say they are healthy -- that's highly doubtful."

What are two chemicals that have been detected by the FDA that are of a concern?

If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force. Mass and weight are closely related. However, the weight of an object can change if the force of gravity changes. On Earth, the force of gravity is the same everywhere. So how does the force of gravity change? It doesnt if you stay on Earth. What if we travel to another planet or moon in our solar system? Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure. They were the first humans to walk on the moon. An astronaut weighs less on the moon than he would on Earth. This is because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon. If his mass on Earth was 80 kg, what would his mass have been on the moon? [Figure 3]
How are mass and weight related?
