between the branches of the forceps, then these are tightened by 

 the screw management of the handles, and next the instrument 

 is committed to the care of an assistant. The crossed suture is 

 then made by the simultaneous passage of the needles through 

 the holes in the branches of the instrument. The directions to 

 insert the needles simultaneously must not be overlooked. If 

 disregarded, the penalty liable to follow will be the tearing of the 

 waxed thread with the points of the instrument, and also a tang- 

 ling of the thread. This method gives a stronger ligature than 

 Mangot's, but it lacks the support furnished by the metallic plate. 

 Method of Marlot. — The methods of Benard and Mangot are 

 here combined. A pecuHar thin forceps is used having dotted 

 grooves on its outer surface to indicate where the stitches are to

be placed. When the suture is finished and the forceps removed 

 a plate of zinc like that of Mangot is appUed, as a means of reten- 

 tion, the zinc plate being thought to be an improvement upon that 

 of lead, on account of its ad^-pting itself better to the parts. 



Method of Chedhomme. — The animal in this method is kept on 

 his feet, properly secured, and a plate of lead applied, as in the 

 process of Mangot. The hernial sac, folded in two on its longitu- 

 dinal axis is then passed through the opening of the plate, the 

 operator making the least possible traction until the remaining por- 

 tion of the umbihcal cord, which is still quite large, is firmly held 

 between the thumb and the index finger of the right hand. Then 

 a stronger traction is made upon the sac, at the same time moving 

 it in various directions, while with the left hand the plate is 

 strongly pressed towards the abdominal walls. Then with the 

 intestines entirely replaced, the operator grasps the sac with the
