The tissue immediately beneaththe synovial membrane is abundantly infiltrated with round cells, and this in-filtration extends back a considerable distance into the subserous tissue, crowd-ing out the normal fat and stimulating a proliferation of the connective tissues,as a result of which there are a great many epithelioid cells and new-formed NON-TUBERCULOUS INFLAMMATIONS OF JOINTS. 499 blood-vessels. The synovial covering becomes eroded in spots of greater orless extent, permitting these proliferating surfaces to come in contact with oneanother and thus favoring the formation of those firm adhesions which char-.

As has been said, this process may extend beyond the synovial tissuesand destroy the surface of the cartilage in places; it may even, in rate instances,extend deeper still, viz., into the hone. These are, as a rule, suppurativecases, and in my experience they have been due to the pneumococcus or thestreptococcus. The finding of b
