316 IODINE SOLUTIONS 



resolvent for chronic synovitis, bursal swellings, muscular 

 pains, slight strains of tendons, thickening of periosteum, 

 and indurations of the udder and other glands. It is also 

 used as a counter-irritant in sore throat in horses, in 

 limited lung consolidation, especially in dogs, and in sub- 

 acute attacks of pleurisy. It is a serviceable antiseptic and 

 deodoriser for unhealthy and malignant wounds. Indolent 

 ulcers are sometimes healed by application of a piece of lint, 

 spread with simple cerate, sprinkled with one to five grains 

 of iodine, and covered with a piece of oiled silk or tinfoil. 

 But excess of iodine must be avoided, otherwise corrosive 

 effects are produced. Dilute iodine solutions are injected, 

 as stimulating antiseptics and promoters of adhesion, into 

 cysts and abscesses from which the contents have been with- 

 drawn. Conjoined with potassium iodide, and oil of 

 turpentine, it is injected into the trachea in hoose in 

 calves. A solution of one drachm in sixteen drachms of 

 rectified spirit is employed after withdrawing the dropsical 

 fluid, as an injection for hydrocele, thoropins, and bursal 

 distensions. On account of its penetrating the hair follicles 

 and ducts, it is serviceable in persistent cases of mange, 

 eczema, and psoriasis, in all forms of ringworm, and in such 

 cases is sometimes mixed or alternated with wood-tar oils, 

 sulphur, or mercurials. Like most effectual antiseptics, it 

 destroys skin parasites, oestrus larvae, and entozoa. It is an 

 effective but expensive deodoriser and disinfectant. 



DOSES, etc. For horses, grs. xx. to 3*- 5 cattle, 3 SS - * 

 3iss. ; sheep, grs. xv. to grs. xl. ; pigs, grs. x. to grs. xx. ; 

 dogs, grs. iij. to grs. viij. Such doses are repeated once or 

 twice daily, given a couple of hours after feeding, in order to 

 diminish the proportion otherwise converted into the mild, 

 insoluble starch iodide, continued for a week or ten days, 

 withheld for a day or two, and, if necessary, again resumed. 

 Larger doses, although they may be given with impunity, do 

 not ensure better curative results. 



Iodine is administered in bolus ; but, handy though this 

 form is for horses and dogs, it is less certain than a good 

 aqueous solution, such as is obtained by mixing two parts of 

 iodine and one of potassium iodide with six or eight of water. 

 The potassium iodide ensures perfect solution and full action
