broad and roughened shoulders, are admirably adapted for 
fine or delicate work, while their bite is quite as firm and 
secure as though they were of the ordinary bulky construc- 
tion. From the extent of their gripe at the points, they hold 
even far and firm enough to be used effectually (should they 
be required for such a purpose) even as torsion forceps, while 
they shut up in such narrow dimensions in the case as to 
take up the smallest possible proportion of space. 
The third instrument (fig. c,) which we may call the 
tenaculum, is difficult of representation, inasmuch as, 
though quite simple in its make, it is one wdiich answers 
three or four very important purposes in the operation of 
neurotomy. Providing the nerve be laid bare by the first 
incision through the skin (w T hich, by an expert operator, it 
will be), nothing will remain to be done save to introduce, 
between it and the artery, the round blunt point of the 
tenaculum, which, being ascertained to have been properly 
and rightly directed, will have to be carried onward to a 
certain distance (marked in the fig. by a dotted line), until, 
the perforation through, the point of the instrument has 
become visible on the opposite side of the nerve ; but, not be- 
yond this point, lest the nerve be brought in contact with the 
cutting or broad portion of the blade of the tenaculum. This, 
the concluding step of the operation, is now effected by a 
sudden advance of the tenaculum underneath the nerve, this 
being all that is required for its section: thus, not only super- 
seding the need of either scissors or bistoury, but saving the 
time generally of necessity consumed in the operation, in 
making use of additional instruments. Also offering, 
should there be occasion for it, a hole, through which the 
operator may insinuate a ligature of thread or silk of any 
sort under the nerve, wherewith to draw it out of its place 
or to tie it ; which he may find it convenient to do, when at 
the time he comes to excise the requisite portion of the 
inferior or senseless portion of it. 
Any information that may be desired on the subject of 
“ neurotomy,” maybe found in the fourth volume ofPercivall’s 
‘ Hippopathology. 5 Meanwhile, our readers will perceive, by
