Anatomy of the foot. The foot is one of the most complex parts of the body. It is made up of 26 bones connected by many joints, muscles, tendons, and ligaments. The foot is susceptible to many stresses. Foot problems can cause pain, inflammation, or injury. These problems can result in limited movement and mobility.
Bricks and tiles. Bricks and tiles are made from clay minerals. When wet, the clay can be shaped, and then fired to make floor, wall, and roof tiles, as well as house bricks. Think about the properties of clay: Easy to shape when wet. Strong and rigid when fired. Impermeable when fired. A thermal insulator.
Portions of the castle are made from the same type of schist as the Vista Rock, creating the illusion of a castle rising out of the park itself. Its light colored stone trim is made of granite quarried from Quincy, Massachusetts. Its roofs are made of colored slate from Vermont, Virginia, and New York. Belvedere Castle was once an open-air structure, with no doors or windows. This changed in 1919 when the United States Weather Bureau moved the Central Park Observatory to the castle. Until that time, weather measurements were taken from the Arsenal at Fifth Avenue and 64th Street where Dr. Daniel Draper founded a meteorological observatory in 1869.
