Th e cure of ail thofe kinds of aneu- 

 rifms is nearly the fame. 



When they are fituated in any of the 

 large cavities of the thorax or abdomen, 

 they are feldom known till fach time as 

 they have become fo large as to be abfo- 

 lutely incurable, when the only thing left 

 to be done is to endeavour to prevent 

 their burfting, which is followed with 

 immediate death, and to palliate thofe 

 painful and uneafy fymptoms which al* 

 moft always attend them. This is to be 

 attempted by moderating the force of the 

 blood, when too great, by blood-letting, 

 and a mild low diet ; by avoiding every 



thing 



An aneurifm of the aorta began at the heart, and was 

 bcfet with a number of bony incriiftations ; at the back 

 part of the beginning of the defcending aorta, there 

 was a hole the Cze of one's thumb, which opened into a 

 large cyft which lay between the aorta and fpine ; thi? 

 cyft was four inches long and two wide, and had railed 

 the aorta from the fpine, and feparated the fourth an^ 

 fifth ribs from one another, and protruded outwardly on 

 the back into a cyft as large as one's fift; it was full of 

 lamellated polypous concretions, and had had no pulfa- 

 tion for a confiderable time. Rat. Medend,par, 4. cap.
