REVIEW— NELSON’S PARTURITION FORCEPS.

vention. They are intended for introduction into the windpipe 
through the aperture made by bronchotomy, and to remain therein 
so long as circumstances may require. Any description we could 
give of them would hardly, without a drawing, convey a notion of 
their construction. They are, we should say, both of them large, 
cumbersome, weighty affairs, and yet they evince ingenuity. Mr. 
Dawes, however, we understand, is about getting one of the same 
kind made in German silver — the present ones being made of pew- 
ter and brass — which, we should say, would get rid of much of 
what we now complain, and be a great improvement. Perhaps, 
we may hope, when he has done so, he will kindly favour us with 
a view of it ; and, should it be found to answer, will permit us to 
have it represented upon paper for the benefit of the profession at 
large. 
Nelson’s Parturition Forceps. 
Dear Sir, — As I said before, I really have not had that practice 
with Nelson’s Forceps that I could wish ; but I am inclined to think 
the principle is good, and that they will be found extremely useful 
in many instances. In some cases I have found them useful ; in 
others, they have slipped off. When the skin is pretty thick, the 
parts will bite ; but if it is thin, they will slip off. 
In mine, the nick of No. 1 is too weak, and on screwing up tight, 
the mouth of the Forceps gaped open and did not hold. The nicks 
on No. 3 ought to be deeper. I prefer No. 2 for general purposes, 
especially for putting in the nostrils, instead of putting hooks into 
the orbits. The great beauty of them is, that they will not tear the 
uterus, should they break out. There would be great danger in 
using them, when at their full length, if the cow should be stand- 
ing, should she fall down, as the other end might hit against the wall 
or ground, and force the forceps off, and through the uterus. Plugs 
should be used at the joints instead of screws, as it is difficult to 
unscrew them. I could not unscrew them, and even broke the 
screw-driver. The screws are made of bad materials. Mr. Nelson 
acknowledges plugs would be best. 
He has sent me three small sizes of forceps — about five inches
