passed between the muscular and the serous coats to the sur-' 

 face. They are placed from 7 mm. to 10 mm. apart and tied 

 after all of them have been placed. When this has been com- 

 pleted the work is fortified by the addition of a second series 

 of Lembert sutures as follows: (Fig. 61) The needle is passed 

 through the serous and muscular coats about 2 cm. from the 

 edge of the groove now made by the Czerny, and then out 

 again about 1 cm. from the groove. It is then brought over 

 to the other side of the groove and entered through the 

 serous and muscular coats 1 cm. from the groove and out 

 again 1 cm. farther (2 cm. from groove). These individual

stitches are placed around or along the whole wound io cm. 

 apart, and then tied. These latter sutures infold the former 

 deeply into the lumen, and the totality of the process brings 

 a large area of peritoneum into juxtaposition, to the end of 

 assuring a union in the greater number of cases. 



Hints on Suturing Wounds. — i. Suture materials and 

 needles must be aseptic because they sojourn so long in the 

 trauma to the advantage of microbian growth. They favor 

 necrosis of the tissues about them by obstructing circulation 

 in the vessels pressed upon by them. They prevent the out- 

 ward discharge of secretion by closing the wound, and thus 

 harbor food for microbes. If, in addition to these presents,
