which it communicates ; and a few burfge of contiguous tendons communicate 
with each other (n). 
^ \ 
Some burfae, even in young and healthy children, communicate with the 
cavities of the joints (o); and in many old perfons I have obferved fuch 
communications formed by ufe or worn by fridlion, although there had been 
no lamenefs nor complaint of pain made by the perfon on that account during 
life (/)). 
There is fome little difference, in different perfons, as to the manner in 
which contiguous facs communicate with each other, or with the cavities of 
the joints: And, particularly, I have obferved, that a burfa as large as a hens 
egg, which is placed behind the tendon of the extenfors of the leg, in fome 
perfons has no communication with the cavity of the joint of the knee ; but 
in the greater number of children, as well as adults, although I obferved the 
appearance of a feptum, or the root of one, yet I found an opening large enough 
to allow one or two fingers to pafs from the burfa into the joint [q).

J^FTER confidering thefe few general obfervations on the burfae, the
