Physiology of Synovial Fluid.
—Pemberton37 and his group conclude from their experiments that diffusible substances pass easily from the blood to the synovial fluid, and that the gastro-intestinal tract must be regarded as being in surprisingly close communion with the joint fluids.
Interstitial Growth in Growing Long Bones.
—Haas38 has performed experiments in growth, using rabbits in which the measurements were controlled by being taken on roentgenograms at the time of operation and at the end of the period of observation. With a constant film target distance there is practically no chance for error, as is the case in making measurements at the time of operation. He concludes that interstitial proliferation of osseous tissue plays no part in the elongation of bone, either in the mature bone or in the young osteoid tissue bordering on the epiphyseal cartilage. Length of bone is entirely dependent on the purposeful
