This apparatus is the same in principle as Defays’ wire 
extractor, but there is only one wire. The principal part 
of the invention is a noose-tube, consisting of a tubular 
piece of round wood, from four to six inches long, and half 
an inch thick. The wire may either be of copper, brass, or 
iron, about sixteen inches long (we have generally used a

or noose at the end (Fig. 17). 
“When it is to be used, the first finger of the left hand 
carries the loop into the vagina of the bitch, and slips it 
behind the occiput of the puppy ; then the two ends of the 
wire are passed through the tube, and this is pushed into 
the vagina under the chin of the foetus ; the operator now 
tightens and secures the wire by giving it a turn round the 
first finger of the right hand, placing his thumb at the end 
of the tube (Fig. 18). A little traction then extracts the

We now employ no other instrument in canine obstetricy, 
and our success has always been complete, even with the 
tiniest toy terriers.
