and the whole operation, even to the coat of collodion, is completed before the meningophylax is relaxed. I will further mention, as an advantage for this operation, that the assistance necessary can be rendered by any one having a moderate degree of self possession and fortitude, and that the after treatment can bo intrusted to most nurses.The operation once finished, no essential part of it need to be repeated, nor does the uncertainty in the maintenance of uniform pressure, so much depended upon in puncture followed by a heniial support, leave the success of the operation in hands little qualified to guard it effectually.-Cincinnati Lancet and Observer. nged 25, March, 18(11, was shot from behind, through flic right knee-joint, with a small pistol-ball, at the moment of passing out and over tho threshold of the door of a saloon, the limb being flexed just us the foot was raised to make the stride. The ball, on entering the popliteal space, evidently did not touch either of the three synovial burses beneath the adductor magnos, nor the popliteal artery, nor either of its branches--the anterior and posterior tibial-as not a drop of synovia or arterial blood issued from the wound either at entrance or exit of the ball ; the latter wound being a little to the left of tho centre of the lower edge of the patella. 1 at first surmised that the ball might have made the half circuit of the joint, but critical examination failed to find any evidence of it. The ball had passed directly through the joint, and without producing any fraCture, as the sequel proved. It must have passed between the two lateral eminences, the tubeiosit.ies or spine of the tibia ; nor was it deflected from its course by the double head of the gaslrocncmius, as they are separated when the limb is flexed. The patella was uninjured. Treatment and Result.-No mechanical pneumatic occlusion of the wounds was applied, as they soon became dry, and apparently healed by first intention-nature obviating the necessity of art appliances. Enormous enlargement of the joint and limb took place, which was combated successfully with free and repeated application of leeches, cold-water dressing, perfect rest and spare diet.
