skull and integument will not be opposite to one ano- 

 ther. This plan is much superior to that of thrusting 

 a needle up the nostril, in the manner devised by Mr 

 Hogg, as in his way we are always poking in the dark, 

 in ignorance of the situation of the instrument, and are 

 in all probability doing so much injury to the delicato 

 parts within the nose as to preclude the possibility of 

 recovery. Indeed, I some time ago examined a head 

 on which Mr Hogg's operation had been twice unsuc- 

 cessfully performed, and found traces of inflammation 

 at the upper part of the nostril severe enough of itself 

 to have occasioned death. The needle had not en- 

 tered the brain, but the ethmoid was very much injured. 

 I believe the instrument is very seldom pushed more 

 than halfway through the bone, at least it never reaches 

 the hydatid, which would appear to be destroyed rather 

 by the inflammatory process which follows the attempt, 

 unfitting the brain for supplying it with the secretions 

 on which it lives, than by any direct injury done to it 

 by the needle.
