lique muscle and its aponeurotic portion internally, and the 
panniculus carnosus and the skin externally. A well developed 
layer of connective tissue is located between it and its sur¬ 
rounding structures at its thickest portion ; the thinner portion 
is closely united to the fascia of the external oblique muscle. 
These layers of connective tissue are favorable places for pus to 
burrow, which makes the treatment of wounds localized in this 
region difficult to treat and the result of the treatment unsatis¬ 
factory. 
Most of the wounds in this region are caused by animals 
jumping fences, gates or stable doors ; forcible blows, such as 
horse kicks, horn thrusts and falls upon sharp or pointed ob¬ 
jects ; together with punctures inflicted by attendants with 
pitchforks or other sharp and pointed implements ; and are all 
wounds that have been inflicted by or with objects that are 
likely to carry infection, and as a natural consequence require 
antiseptic treatment. 
In carnivorous animals the abdominal tunic is not well de¬ 
veloped ; it consists of a thin layer of fibrous tissue ; the walls 
are not tense; wounds are not common ; and the treatment is 
generally satisfactory. Abdominal wounds in the dog are not 
serious if given prompt attention.
