what is known as the Listerian or antiseptic treatment 

 of wounds. Lister was the father of antise'ptic surgery, 

 the adoption of which has reduced the mortality result- 

 ing from wounds to very small proportions. Wounds 

 heal in various ways, depending on the severity of the 

 wound and the manner in which it was inflicted; exam- 

 ples of varieties of wounds are (a) clean cuts as made by 

 a sharp knife, these as a rule heal readily; (b) punctures 

 caused by running of a blunt body into a part, such as 

 the point of a shaft, repair of this variety is slower 

 and the injury is more serious than the first kind; (c) 

 lacerations, tears such as wounds made with a saw or 

 jagged edged instrument; repair is slow in these wounds 

 and pus is usually abundant; (d) bruises in which case 

 the skin is rarely broken. 



Manner of healing of wounds: 



1. By immediate union, the parts are brought together 

 in exact contact and unite at once; there is very little 

 material needed in this case, therefore any inflammation 

 present must have been slight. 



2. Union by first-intention, in this form the divided 

 edges are glazed over by a fluid (lymph) thrown out 

 from them, or the clotting of a thin film of blood; this 

 material holds the parts together until permanent union 

 by cells takes place; the fluid has to be got rid of before 

 permanent healing takes place, a scar results from this 

 and the following method. The lymph thrown out 

 becomes vascular, i. e., little (capillary) blood vessels 

 form in it. 



3. Granulation is the commonest form of healing in 

 the lower animals, it is a tedious process accompanied as
