Themetacarpo-phalangeal joint of the right ringfinger is normal except for slight narrowingof the joint space. The interphalangeal jointspresent various degrees of the same pro-cesses. Some of the interphalangeal jointsdescribed in the metacarpo-phalangeal jointsare normal in appearance. Others, espec-ially the proximal interphalangeal jointsof the fourth and fifth phalanges of the lefthand, are more or less obliterate
