nated lime in a gallon of water. This will sterilize 8000 gallons of any 

 ordinary clear river or well water in 15 minutes. Then, to combine with 

 any free chlorine left in the water, and so remove it and its taste, a gallon 

 of sodium thiosulphate solution (containing I/2 lb. of the salt) is added 

 to the 8000 gallons of drinking water. A 1 to 1,000 solution of bleach is 

 most effective in sterilizing all dairy utensils in place of steam (Winslow, 

 Amer. Vet. Review, Aug. 1915). Upon the body, a 2 or 3 per cent, 

 solution of chlorinated lime is employed as a stimulant, deodorant, and 

 antiseptic for decubitus, foul-smelling and gangrenous sores, severe burns 

 and indolent ulcers. It it used in 10 per cent, solution as a parasiticide 

 in ringworm and scabies. A 1 per cent, solution forms a valuable wash in 

 ulcerative stomatitis. Chlorinated lime may be prescribed, with an equal 

 amount of lard, upon ulcers when a stimulating action is desired. Chlo- 

 rinated lime (gr.xv. in §ii. of water) is one of the most effective antidotes 

 for snake bite, when injected in several places in the region of the lesion. 

 Its internal administration is undesirable. The solution of chlorinated 

 soda is a slight caustic, deodorizer and antiseptic preparation on indolent, 

 sloughing, foul-smelling surfaces. It may be prescribed in sore throat, 

 or ozena, as a spray, or injected into the uterus, vagina or rectum. It is 

 commonly diluted with 8 to 10 parts of water. Chlorinated lime has been 

 found the most powerful antiseptic in surgery of the Great War. It is 

 used in powder (known as eupad), made by grinding it up in a mortar 

 and mixing it with an equal weight of boric acid. Or, is used in solution, 

 made by shaking 25 Gm. of eupad with a liter of water, allowing it to 

 stand for a few hours and filtering. This is known as eusol, and is em- 

 ployed for wet dressings or for irrigation of wounds, while eupad is used 

 as a dusting powder. Also see Dakin's solution, chlorazene, and dichlora- 

 mine-T, p. 510.

Bbomtjm. Bromine. Br 



Derivation. — From seaweed and mineral springs.

 tion of an irritating vapor. Soluble in 30 parts of water, and readily soluble in 

 alcohol and ether. Of no value in veterinary medicine.

Synonym. — Kalium bromatum, P. G. ; bromure de potassium, Fr. ; brom- 

 kalium, G. 



Derivation. — Obtained from liquor potassse, bromine, and charcoal by the 

 same process described in malting potassium iodide (p. 190). 



Properties. — Colorless, or white, cubical crystals, or as a granular powder; 

 odorless, and having a strongly saline taste. Permanent in the air. Soluble in 

 about 1.5 parts of water and in 250 parts of alcohol.

 *SoDii BROinrouM. Sodium Bromide. Na Br. (U. S. & B. P.) 



Synonym. — Natrium bromatum, P. G. ; bromure de sodium, Fr. ; bromna- 

 trium, G. 



Derivation. — Similar to potassium bromide. Liquor sodae is used instead of 

 liquor potassae. 



Properties. — Colorless, or white, cubical crystals, or a white, granular powder; 



*Ammonii bromidum, lithii bromidum, calcii bromidum and strontii bromidum 

 are also official. These salts are given in the same doses as sodium bromide.
