But whatever caufed the pain in the right fide, upon 
the removal of the pins from the {efcphagus^ that 
caufe continued to ad; until all the three pins were 
diicharged at the left flaoulder, for fo long did the 
pain in the right fide continue. 
The thicknefs of the two fejTaiiy the rhofnboides, 
trnpefi us mufcles may be thought too great for 
pins five quarters of an inch long to penetrate all of 
them at the fame time. But if it be obferved, that 
one of the pins was difcharged at a time when neither 
of the two others could be felt with the probe, it may 
be fuppofed, that one of the three pafied into the 
rboniboides, and trapeJiiiSy whilft the two others re- 
mained in the ferrati, and there continued until the 
firfi: was difcharged at the ti'apefms j after which they 
took the fame courfe, and were difcharged at the 
fame outlet. 
Thus might we give a very probable account of 
this extraordinary cafe, had the pins been difcharged 
at the right fhoulder, but they were difcharged at the 
left. By thofe who think that, the nerves commu- 
nicating with one another, the caufe and effed pro- 
duced may be on oppofite fides of the body, it may 
be faid, that the pins might be forced from the osfo- 
phagus into the mufcles of the left fide, notwith- 
ftanding the pain was felt in the right. This will not 
be generally allowed. Neither can I perceive any 
reafon why a tumor exadly refembling that from 
whence the pins were afterwards difcharged at the 
left fiioulder, fiiould arife upon the right, and difperfe 
without coming to fuppuration. 
Since I drew out the above account, I have fecn a 
cafe nearly fimilar to it, recorded in the Philofophical 
Tranfac-
