Contracts against the public policy of the law, are equally void as if they were in violation of a public statute; a contract not to marry any one, is therefore illegal and void. See Void. 5.
Phosphorus is a fascinating element that occurs in at least three very different forms. If left exposed to the air, it catches fire on its own. It also glows in the dark. Today, its most important use is in the manufacture of phosphoric acid (H 3 PO 4 ).
How is it used? Phosphorus tests are most often ordered along with other tests, such as those for calcium, parathyroid hormone (PTH), and/or vitamin D, to help diagnose and/or monitor treatment of various conditions that cause calcium and phosphorus imbalances.
