Although true aneurifms of the arm 

 are fo much talked of, and moft authors 

 till ct late mention thofe which have fol- 

 lowed bleeding or wounds of the arm as 

 trueones : Yet I have not in them met with

 which was of the mixed kind, in which 

 Mr Morand * fays he not only found 

 the artery perforated, but likewife dilated 

 to double its natural fize.
