Authors mention true aneurifms iii 

 the brain ; but, I have met with no ac- 

 count of any within the £kull, in fuch 

 books as I have confulted. Indeed, in the 

 yfcJa Uaffn'ienfta *, there is mention made 

 of an aneurifm in the head ; but the head 

 was not opened after death, nor is there 

 any proof of the difeafe being an aneu- 

 rifm ; it feems rather to have been a fup- 

 puration within the fkull. 



Tl'.Tius, Fernelius, Pare, and a great 

 many other authors, mention aneurifms 

 being frequent in the neck ; but H eider f 

 very juftly remarks, that this has not beeii 

 found conformable to obfervation. i^e*
