70 Oxygenated Water. 



plications may be made of this process. Navigation, medicine, 

 inuvholesome' manufactories, will derive incalculable advantages 

 from it. This explains why meat merely dried in a stove does 

 not keep, while that which is smoked becomes unalterable. We 

 have here an explanation of the theory of hams, of the beef of 

 Hamburgh, of smoked tongues, sausages, red herrings, of wood 

 smoked to preserve it from worms, &c. &c." 



Dr. Jorg, Professor at Leipsic, has since made many successful 

 experiments of the same nature. He has entirely recovered se- 

 veral anatomical preparations from incipient corruption, by pour- 

 ing this acid over them. With the oil which is produced from 

 Avood bv distillation in the dry manner, he has moistened pieces 

 of flesh already advanced in decay; and, notwithstanding the heat 

 of the weather, soon made them as dry and firm as flesh can be 

 rendered bv being smoked in the smoking-room. All traces of 

 corruption vanish at once when the vinegar of wood, or the oil 

 oficood, is applied to the meat with a brush. The Professor has 

 also begun to prepare mummies of animals, and has no doubt of 

 success. He promises great advantages to anatomy, domestic 

 oeconomy, and even to medicine, from this discovery (for the re- 

 medy seems very fit to be applied internally and externally in 

 many disorders), and intends to publish the result of his further 

 experiments. 



OXYGENATED WATER. 



We noticed in our last this new liquid, obtained by M. The- 

 nard in prosecuting his experiments on the oxygenized acids. It 

 is a combination of oxygen with water. Thfe quantity of oxygen 

 contained by water when thus saturated is 850 times its volume, 

 or twice its proper quantity. Its specific gravity is 1'453, and 

 on being poured into water it sinks through it at first like a sy- 

 rup, though it is very soluble. Applied to the skin, it has an in- 

 stant action, and renders it white, causing a smarting, which con- 

 tinues longer or shorter as the quantity is more or less: if con- 

 siderable, it destroys the skin. Applied to the tongue, it has the 

 same cflTect, and thickens the saliva. Its taste cannot well be de- 

 scribed, but it resembles that of an emetic. It acts powerfully on 

 oxide of silver : each drop let fall on it dry, causes an explosion, 

 with an evolution of light if in a dark place. The peroxides of 

 manganese and of cobalt, and the oxides of lead, platinum, pal- 

 ladium, gold, iridium, and some other metals, act powerfully on 

 oxygenated water. Many metals when minutely divided produce 

 the same phasnomena, as silver, platinum, gold, osmium, iridium, 

 rhodium, and palladium. In all these cases the extra oxygen is 

 disengaged, and sometimes that of the oxide ; but in others a 

 part of the oxygen combines with the metal, as with arsenic, 

 molybdenum, tungsten, and selenium. These metals are acidified, 



frequently
