VACCINE-THERAPY 141 



rusty rails, wire fencings, agricultural tools and implements, 

 etc., a dose of antitetanic serum injected will produce 

 complete protection for three or four weeks. 



In addition, such wounds should be cauterized and even 

 scarified, and, above all, severely dressed with very strong 

 solutions of tincture of iodine. If the infective wound is 

 low down the leg (below the knee), in such cases we believe 

 we have had benefit by performing neurectomy. The 

 application of Bier's treatment, recommended by some to 

 check absorption, we consider detrimental to the patient. 

 This procedure causes an increase of pain to the patient 

 and aggravates the tetanic symptoms. 



Where lockjaw is the result of an amputated tail, 

 we reamputate, taking off several inches, if possible, and 

 inject tincture of iodine at the root of the tail. 



The intratrachial injections of lugol solution we have 

 found not only to mitigate the severity of the attack in 

 some cases, but in those cases which do recover, the duration 

 of convalescence is considerably shortened. 



The subcutaneous injections of mag. sulph. in solution 

 in our hands have proved of no curative value, and the 

 same may be said of the rectal injections of liquor ferri 

 perchlor.
