    Crystalline needles and spindles of tropomyosins from the smooth muscles of pig stomach, pig urinary bladder, duck and goose gizzard, the striated muscle of crab (Eriocheir sinensis M. Edw.) and the adductor and foot muscles of bivalves (Anodonta pacifica Heude) and of paramyosins from the two last-mentioned muscles were examined under a HU-11 electron microscope. The samples were either stained with phosphotungstic acid or shadow-casted with Pt or Pt-Ir. All of these showed distinct cross striations. The banded structure and the appearance of the tapering ends suggested that they were ordered, one-dimensional paracrystalline arrays, not true crystals with threedimensional regularity.The paracrystals of the tropomyosins investigated were all endowed with cross striations with a fundamental repeat period of n×200A, where n=1,2. The 400A period may or may not be accompanied by an intermediate line. These spacings were identical with those of the open-network lattice observed in true crystals of rabbit tropomyosin.The patterns of paracrystals of duck or goose gizzard deserved special attention. In addition to the 400 A and 200 A periods or intraperiod spacings, a prominent 800A (n=4) period was often observed. It seemed not unlikely that 800A corresponded to the particle length of this tropomyosin. Shadow-casted specimens of paracrystals of Anodanta adductor tropomyosin also revealed axial periods of about 800 A.The patterns of the paracrystals of paramyosins obtained from the foot and adductor muscles of Anodonta resembled closely those obtained from the adductor muscles of its marine relatives reported in literature. There were 4 equally-spaced intraperiod lines in a period of about 700 A, the spacing of these lines being 140 A.Obtained in the presence of high salt concentrations, the paracrystalline arrays of the tropomyosins from the adductor and foot muscles of Anodonta differed significantly and interestingly from those obtained conventionally in the presence of low salt concentrations. Although the fundamental repeat of about 400 A remained the same, the intraperiod fine spacings changed now from the 200 A characteristic of tropomyosin to the 140 A characteristic of paramyosin.On the basis of electron microscopic periodicities, it was tentatively suggested that tropomyosin and paramyosin were two different kinds. of proteins. Nevertheless, when they co-existed in one and the same muscle, such as the adductor or foot muscle of Anodonta, the existence of some genetic relationship between the two may have to be reckoned with.

    The subject is treated on the basis of field experiences and large amount of geochemical data. It is proposed that (1) the content and distribution of organic matter in continental source rocks are something related to the types of lake sediments deposited, generally expressed by the presence of organic carbon, chloroform extract asphalt "A" and hydrocarbons content (2) From the study of the types of organic matter by means of chromatogram, infrared spectrum, chromatogrammass spectrogram, it has been found that in addition to the above, sedimentary facies zone also plays a part and that the source rocks contain kerogen of many types. ( 3 ) According to the genetic relationship between soluble and insoluble organic matter in the source rocks, coupled with data of kerogen, organic matter in continental source rocks is classified into 5 types: the sapropel type, the humus-sapropel type, the sapropel-humus type, the humus type and kerogen coal.
