Europe except Great Britain. And * Mr. Chefelden, in his Obfezva- 
tions on Le Dran’s Operations, recommends the trephine in pri- 
vate operations, but the trepan when expedition is neceflary, as 
ma battle or fea engagement, The handle of the trephine he 
defires to be made fo heavy that the hand may have little more 
to. do than to dire@ it; but } Mr. Pott, differing in this particu-— 
lar from him, advifes the handle to be made of light wood. 
Tue inftrument delineated by Mr. Sharp, and approved of by 
. him, is an exact copy of that recommended by John Woodall, 
Surgeon to St. Bartholomew’s Hofpital in London, and Surgeon 
General of the Eaft India Company in the reign of King Charles. 
the Firft, in a fecond part of a work of his, entitled “'The Sur- 
“ geon’s: Mate, or Military or Domeftique Surgery';” he gives a. 
plate and a long defcription of an inftrument of his own inven- 
tion, which he calls a Yrafne (a-tribus finibus), it being made 
with a handle, that each extremity might ferve the purpofe of an 
elevator of a different form; thus combining three inftruments 
in one. The edition of the work now before me was printed in 
the year 1639, but I find, from the preface, he had written it in the: 
year 1626, when in Italy; and as his defcription nearly corref- 
ponds with thofe recommended by Mr. Chefelden and Mr. Sharp, 
it is probable on his recommendation it had before their time 
been admitted into practice. My late friend, the celebrated { Dr.
