CHAPTER I. 

 SUPPURATION. 



Suppuration was at one time supposed to be an 

 inevitable outcome of the majority of wounds, and, 

 although bacteria were observed in the discharges, the 

 old habit of thought and insufficiency of information 

 caused most surgeons to believe that they were sponta- 

 neously developed there. 



The development of antiseptic surgery, and the ex- 

 tremes to which it was carried by specialists, almost 

 attain to the ridiculous, for not only were the hands of 

 the operator, his instruments, sponges, sutures, ligatures, 

 and dressings kept constantly saturated with irritating 

 germicidal solutions, but at one time the air over the 

 wound was carefully saturated with pulverized antiseptic 

 lotions during the whole operation by means of a steam 

 atomizer. This rather monstrous outcome of the appli- 

 cation of Lister's system to surgery was the very natural 

 result of the erroneous idea that the germs which cause 

 the suppurative changes in wounds entered the exposed 

 tissues principally from the atmosphere, and that the 

 hands and instruments of the operator, while certainly 

 means of infection, were secondary in importance to it. 



The researches of more recent date, however, have 

 shown not only that the atmosphere cannot be disin- 

 fected, but also that the air of ordinarily quiet rooms,
