ing in water, to remove the salt, and then immersing in 

 the iodate water. Putrid rain-water became agreeable in 

 taste after twenty-four hours when mixed with one quarter 

 its volume of the iodate water. Rain-water, in which a hun- 

 dred thousandth of the iodate was dissolved, continued un- 

 changed for a year. Fresh butter covered with the solution 

 kept three weeks, and rancid butter was improved by this 

 treatment. 



None of the above articles of food, after being treated as 

 described, gave any indications to the taste of the presence 

 of iodate, which, taken in large doses, even to the amount of 

 one gramme, act like a dose of quinine, and increased the ap- 

 petite, without, as was believed, producing any injurious ef- 

 fect. 



Sonstadt also holds that the iodate will be useful in cases 

 of infectious disease, as, after exposure to foul odors, he de- 

 tected in himself the premonitory symptoms of a typhoid 

 attack, which entirely disappeared on taking 0.1 gramme of 

 the iodate. It has also been successfully applied for curing 

 toothache caused by the decay of the bone. 21 A, April,

ACTION OF COMPRESSED AIR ON MEAT. 



According to Bert, meat does not putrefy in compressed 

 air, but merely undergoes a slight change in external appear- 

 ance. Even when putrefaction has been begun, it is said to 

 be entirely arrested when the substance is introduced into a 

 condensed atmosphere. 18 A, August 21, 1874, 589.
