334 PRINCIPLES OF VETERINARY SURGERY 



called "granulations," whose development is either normal 

 or abnormal. In normal granulations the wound is of a 

 good character and of good aspect, and the granulations of 

 which it is composed are regular, rosy, and firm. In the 

 abnormal granulations the cicatrization is slower, more ir- 

 regular and the breach assumes variable characters. The 

 granulations may be exuberant when they pass considerably 

 beyond the level of the sttrface to be repaired, fungous when 

 they lie outside of the limits of the wound and erethic when 

 the sensibility is excessive. And finally, they may become 

 the seat of infectious complications called diphtheritic gran- 

 ulations which are coated with a pultaceous, yellowish sub- 

 stance that hinders disinfection. The surface is smooth and 

 is only disinfected with the greatest difficulty. These mouldy 

 sores, well known and described by military veterinarians, 

 are especially frequent at the close of summer, in animals 

 exposed to water or treated continually by showering. 

 Under the outer pultaceous coating the granulations are 

 reddish and flabby, bleed fronii the slightest contact, and 

 show no tendency to complete their organization. The pro- 

 duct that covers the granulations is composed of cellular 

 waste, colonies of streptococci and most frecjuently mucus. 

 They are frequently complicated with lymphangitis. 



Lastly there are cases where the scar develops in the 

 regular manner but sustains injury during the process of 

 healing. This injury is frequent in animals that again fall 

 upon their incompletely healed knees and tear open the scar 

 that was closing around the breach. The new lesion is often 

 deep and extensive, but heals by a perfectly normal process.

DEFINITION. — In both immediate and secondary cica- 

 trization the growth of granulations first brings the scar to 

 the level of the wound and thus fills the traumatic cavity;
