The elements of medical chemistry : embracing only those branches of chemical science which are calculated to illustrate or explain the different objects of medicine, and to furnish a chemical grammar to the author's Pharmacologia . er to drive theatmospheric air from the bottle, the pre-sence of which might otherwise occasionexplosion. 459. By the combustion of these two gases, in the pro-portions necessary for the production of water, the heatproduced is very intense, and far exceeds the highest heatof our furnaces, and may be used to fuse bodies, intractableby any other fire raised by combustion. The easiest andmost efficient mode of exciting and applying this heat is bythe Oxy-hijdrogen blow-pipe, in which these gases, afterundergoing compression in a mixed state, are propelledthrough a capillary tube, and exposed to combustion. 460, Hydrogen enters largely into the composition of ani-mal and vegetable bodies. In the human body it is found toexist in a gaseous state in the alimentary canal; to a smallextent only in the stomach, but in larger proportions in thegreat, and in very considerable quantities in the small intes-tines, while oxygen has never been found in any part of theprimae viae except the 234 parish medical chemistry. Carbon. 461. If vegetable matter, especially the wood of plants,be exposed to heat in close vessels, the more volatile partsare expelled or decomposed, and there remains a black shi-ning porous body, termed Charcoal. This body, however,always contains several foreign ingredients, as water, air, andsaline and earthy matter. It is to the perculiar inflammablematter, divested of these impurities, that the term Carbonis applied. It is an abundant principle both in vegetableand animal substances, and may be procured from them byheat. The purest known form in which it can be obtainedis that deposited by oils or spirits of wine, on passing throughignited tubes. 462. Extraordinary as the fact may appear, the experi-ments are two numer
