Summary. Turnover rates of muscle protein in eardiac and skeletal muscle have been measiu'ed in doj^s using a continuous iiifiwion of '-"C-tyrosine, and in fowls, rats and mice after a pulse label of either ''H-leneine or ''tl-aspartate. In all spei'ies the total inixetl protein from \'entricie turned over the most rapidly. Tonic muscles predominantly comprised of red fil)res were intermediate in rate and twitch muscles comprised of predominantly white fibres had the slowest rates of turnover. This same progression of turnover rates was also .seen in myofibrillar and sareoplasnnc protein fractions and with myosin. The RNA eoneentrations of the muscle tissue were hij^hly correlated with the turnover rates. It is suggested that the turno\er rate of musele protein is related to the function of the muscle.

“…K. Hill, 1964;Franzini-Armstrong & Porter, 1964), although their openings have seldom been clearly seen in electron micrographs of mammalian or adult amphibian muscle. In amphibians there is one transverse network per sarcomere, at the level of the Z line, while in mammals there are two per sarcomere, one near each boundary between A and I bands; in a bird, both of these patterns have been seen in different muscles (Page, 1969).…”

SUMMARY1. The sarcomere length (s) of chick slow and fast muscles (anterior and posterior latissimus dorsi (ant. lat. dorsi and post. lat. dorsi)) was measured by the method of light diffraction. In resting ant. lat. dorsi, s changed from 1-76 to 2-30 ,um during stretch from minimum to maximum muscle lengths in situ, and in resting post. lat. dorsi from 2-18 to 2-63 Itm.2. Resting tension started to rise in ant. lat. dorsi when s exceeded 1-7-1-8 gim, but in post. lat. dorsi not until s exceeded 2-6-2-7 4am.3. X-ray diffraction patterns showed that ant. lat. dorsi contains collagen filaments; collagen reflexions were not seen in patterns obtained from post. lat. dorsi with the same exposure time.4. The relation between active tension and sarcomere length was similar for ant. and post. lat. dorsi. The maximum active tension was observed when s = 2-05-2-15 #m in ant. lat. dorsi, and when s = 2-10-2-25 ,m in post. lat. dorsi.5. X-ray diffraction patterns from both muscles showed that the periodic structures of the thick and thin filaments are similar to those in frog and rabbit skeletal muscles.6. The volume of the myofilament lattice in resting ant. lat. dorsi was 3-06 (± 0*14) x 109 A , in resting post. lat. dorsi 2-98 (± 0.09) x 109 A .These values are close to that of frog skeletal muscle. The lattice volume remained constant in ant. lat. dorsi and post. lat. dorsi over the range of sarcomere lengths found in situ. 7. The equatorial diffraction patterns from the ant. lat. dorsi in rigor (glycerol extracted) were different from that of the resting muscle, and suggested that a large number of cross-bridges were attached to the thin
