unite as readily as the serous, and if the sutures are made of 
catgut, which usually slacken in a short time, and leave a 
wound in the mucous surface exposed to infection from the con¬ 
tents of the alimentary canal. 
A third method has been described by him which is known 
as the Jobert’s invagination suture (Fig. 2). In this procedure 
both ends are folded inward, and the stitches are made by pass¬ 
ing the needle through all the coats into the lumen of one end 
from without inward, then through the other end in the same 
manner, then through the first end about four millimeters far¬ 
ther from the end than the point of entrance ; and when the re¬ 
quired number of stitches have been applied they are ligated, 
which brings the one end into the lumen of the other end of the 
intestine to be approximated. This invagination method is not 
a very reliable way of reestablishing continuity in intestines 
of domestic animals, although it is a very ingenious pro¬ 
cedure.
