    more abundant as the temperature of the atmosphere in which it is formed is higher. It is a slow combustion caused by the oxygen of the atmosphere. It is used on this account in endiometry. Phosphorus melts in warm water at the temperature of 32° R. When phosphorus is melted and exposed to the ac- tion of oxygen gas, it immediately undergoes combus- tion, and spreads a very brilliant light. It is capable of being inflamed in common air at the temperature of 40° R. A sudden blow, friction, and even compression will induce the active combustion of phosphorus. It is ne- cessary therefore to be very cautious in using phospho- rus, and for the same reason it should be always kept under water. When burned, phosphorus throws off a large quantity of white and suffocating vapour, which consists of phos- phorus acid, if the combustion takes place in atmosphe- ric air, and of phosphoric acid, if in pure oxygen. Phosphorus combines with hydrogen and forms a gas,' called phosphoretted hydrogen, which becomes lumi- nous by simple contact with the atmospheric air: it unites with sulphur in different proportions, with carbon, the metals, &c.
