Perhaps sir, if you could find a place in your Journal for the 

 above article on iodine, it might be the saving of some lives, 

 or at any rate, it would give a new peg to hang a hope upon, 

 and thus tend to relieve the patient from that constant dread 

 of impending death, which places him in a situation like that 

 of the person at the feast of the tyrant of Syracuse, who 

 found himself sitting under a sword suspended by a hair. 



8. Notice of the manufacture of the chloride of lime, and 

 of some of its leading uses, in a letter from Mr. G. W. Car- 

 penter to the Editor, dated Philadelphia, Jan. 1 829. — The 

 chloride of lime is manufactured on a very large scale, at the 

 Maryland chemical works at Baltimore. A large chamber 

 lined with lead is made use of, and about 5000 lb. of hydrate 

 of lime is placed thinly on moveable shelves, the chlorine 

 gas is then introduced into the chamber and is absorbed by 

 the lime, the top shelves are saturated first, the lime is then 

 stirred and the shelves reversed, the top placed at the bot- 

 tom and the bottom at the top, and so on through the whole, 

 introducing additional quantities of chlorine as the shelves 

 are transposed and the gas absorbed or united. The chlo- 

 ride thus made is considered fully equal to the best bleaching 

 salt which can be imported. 



It is, you know, an article extensively employed in the arts; 

 especially in bleaching ; one grain of it will destroy the col- 

 oring matter of two grains of the best Spanish indigo. Al- 

 though the chloride of lime is applicable to so many impor- 

 tant purposes, still its usefulness is as yet so little known, that 

 I will select a few% from its various important applications. 



It is generally employed in solution, which is made in the 

 proportion of four ounces to one pint of water, and as only 

 about one half of the lime is dissolved, it will be necessary to fil- 

 ter, in order to obtain the clear solution. Dilute one part of 

 the liquid with 40 parts of water, a pint with five gallons, or a 

 a wine glass full to three quarts of water, stir the mixture 

 and it is then fit for use. It is the most powerful, disinfecting 

 agent hitherto discovered, and an instantaneous destroyer of 

 every bad smell. It is an infallible destroyer of all effluvia, 

 arising from animal, and vegetable decomposition, and eflfect- 

 ually prevents their deleterious influence, hence, it is particu- 

 larly recommended to the attention of those, residing in ep- 

 idemic districts, as there is reason to expect, that the mix- 

 ture sprinkled about apartments would prevent the access
