is lined with a Slip of Buff-Skin, or clofe Shamoys 
(KK, Fig. 2. Tab. III.) to prevent the Tumours 
flipping when once it has been laid hold of. 
BE) is the Extremity of the Forceps , to be held 
in the Hand of the Operator. 
E F, GH 7 are the Pieces which conned the two 
Parts of the Inftrument, inflead of the common Joints 
or Rivets of the other Forceps , in a very advantageous 
manner. Thefe Pieces make the principal Utility of 
this Invention. 
Fig. 2. Tab. III. reprefents the Pincers taken to pieces 
in two Parts. 
One eafily fees that the Piece E is to go into the 
Notch gg, fo that the Screw f may pafs through its 
Slit, and that the Nut F, put on upon that Screw 
f is to keep the Whole together : But one thing 
which the Figure cannot fhew, is, that this Piece E is 
moveable in the Diredion lengthways of the Forceps, 
to anfwer the different Openings of the Cheeks. You 
may obferve in b the Pin upon which this Piece 
turns. 
The Piece G likewife receives the Screw h into 
its Slit 5 and the one and the other is flopped by the 
Nut H. But an eflential Remark with regard to the 
Piece G, is, that it rnufl have the Figure of an Arch 
of a Circle, the Radius whereof is the Inftrument 
itfelf j that is to fay, it ought to be the Portion 
of an Arch of a Circle, the Center of which is at the 
Extremity of the Inftrument } and this to the end 
that in the fmall Extremity of the Pincers, the Ends 
of the Cheeks find themfelves over-againft each other, 
whatever Opening one may give to the larger Extre- 
mity, or to the Handle G H ,
