44 2 Mr. Cooper’s Observations on the 
which she could not distinguish, unless it was pressed against 
her head. After the operation, I instantly repeated that expe- 
riment, and found that, with the ear I had punctured, she could 
distinctly hear the watch, though it was held at the distance of 
several feet ; whereas, with the opposite ear, she was still un- 
able to hear it beat, unless, as before, it was pressed against her 
head. Mr. Stocker, apothecary to the hospital, witnessed the 
effects of this operation. 
On the 28th of the same month, I performed the same ope- 
ration on her right ear, in the presence of several medical gen- 
tlemen, who satisfied themselves as to the cause and degree of 
her deafness ; the ear upon which I first operated having been 
purposely closed. As soon as the puncture was made, the trial 
with the watch was again resorted to ; and she could hear it beat 
at the same distance as with the other ear; and could hear us 
speak, in the common tone of voice, as distinctly as we could 
hear one another. 
To ascertain with certainty whether she really heard the 
beating of the watch, I placed it at a considerable distance from 
her, and asked her if she still heard it. To which she answered, 
“ Yes, perfectly.” I then stopped the watch, without her know- 
ing it ; and, the question being repeated, she listened for a while, 
then said, “ I must have been deceived, I do not hear it but, 
the moment I set it again in motion, she called out, “ I hear it 
“ now, and as well as I ever did in my life.” In this state her 
hearing continues; the deafness having never, at any time, 
returned. 
The cause of this deafness was obviously in the throat. The 
disease had not existed sufficiently long to produce any other 
derangement in the ear ; and the good effect of the operation
