    This paper is a description based on the Sinanthropus materials including5 teeth and two fragments of humerus and tibia recovered since the restorationof the Choukoutien excavation in 1949.The teeth of Sinanthropus are much bigger than those of modern man.Theleft medial upper incisor bears well-developed basal tubercle on the lingualsurface.The upper first and second premolars are robust in size and theirchewing surfaces are covered with wrinkles of special patterns.The crowns ofthe first and second lower molars are characterized by their lowness in relationto their lengths and breadths.Pronounced cingulum is present on the buccalsurface of the crown.The humeral shaft is almost identical with that of modern man.Thetibial shaft is slender and its anterior border is blunt.The walls of the tibiaare extraordinarily thick and its medullary cavity is very narrow.The results of the study of Sinanthropus pekinensis by the present authorsand others clearly show that the upper extremity bones of Sinanthropus arealmost identical with those of modern man;the lower extremity bones are definitely human in form and appearance,but possess also some primitive cha-racters.The teeth and skulls possess many primitive features.The cranialcapacity is considerably smaller than that of recent man.It is due to labour,and the operations of the hands that the upper extremity is differentated fromthe lower one.The differentiation of the extremities is followed by the deve-lopment of the brain and the brain case.These results further enrich Engels'theory of the transition from ape to man and testify to the truth that“labour(?)eated man himself”.

    (1) Sodium salt of reduced codehydrogenase I has been obtained in good yield as a dry powder from codehydrogenase I by reduction with alcohol and alcohol dehydrogenase. This preparation was stable for at least 5 months when kept dry at -15℃. (2) The properties of the particle-bound codehydrogenase I cytochrome reductase system in heart muscle preparation were found to differ considerably from those of the soluble enzyme as obtained by Mahler et al. Among other things, the affinity for cytochrome c of the particle-bound enzyme is much greater than the soluble enzyme. The Michaelis constant for cytochrome c of the former is only one twelfth of that of the latter.(Fig. 2A). (3) With either oxygen or excess cytochrome c as electron acceptor, it was found that the overall activity, in terms of rate of oxygen consumption or cytochrome c reduction, when both succinate and reduced codehydrogenase I were oxidized simultanously, did not represent the sum of the rates of oxidation when these two substrates were separately oxidized but equalled only the faster of the two separate oxidation rates(Fig. 5, Tables 1, 2). If 2,6-dichlorophenol indophenol was used as the electron acceptor, the overall rate of simultaneous oxidation of these two substrates was found to equal exactly the sum of the rates of separate oxidation(Table 3). (4) When either oxygen or excess cytochrome c was used as the electron acceptor, reduced codehydrogenase I and succinate each inhibited the rate of oxidation of the other(Figs 4, 6 & 7). Evidence has been presented to show that the inhibition of succinate oxidation by reduced codehydrogenase I is not due to the accumulation of oxaloacetate. (5) When malonate was also added to the reaction mixture, succinate no longer produced any inhibition of the oxidation of reduced codehydrogenase I(Fig. 8). (6) It is therefore concluded that in heart muscle preparation both succinate and reduced codehydrogenase I are oxidized by cytochrome c through a common, velocity limiting factor. This is in accordance with the view previously reached by some workers from studies on the action of certain inhibitors. However, it should be noted that in our experiments no agents which might produce any conceivable change in the colloidal structure of the enzyme system has been employed. (7) It should be emphasized that our results clearly show that great caution must be exercised in drawing conslusion on the role an enzyme might play in a complex enzyme system from studies of the properties of a solubilized enzyme. (8) It is believed that the competition of two enzyme systems for a common linking factor as demonstrated in this report has provided a new method for studies on the mutual relations of two or more enzyme systems.

    The fore foot of the mole is three times larger than its hind foot. Serialsections of the spinal cords of two adult moles were prepared for a comparativestudy of the motor centers of the fore and hind legs in the cervical and lum-bar enlargements. The magnitude of the motor cells in the anterior horn of the cervicalenlargement (centers of leg muscles), wheh taken collectively, is 2.5--2.8 timesthat of the lumbar enlargement. The motor cells in the posterior part of theanterior horn (posterolateral and retroposterolateral columns,--centers of footmuscles) of the cervical enlargement, if compared separately, are 3.4--4.0 timesthose of the lumbar enlargement. The two columns innervating the foot muscles contain enormous cells,break into subcolumns and thrust posterolaterally to form a new "horn" whichis even larger than the original anterior horn on many levels. The upper part of the retroposterolateral column (centers of digital mus-cles) is better developed than the lower part. With cells exceedingly hypertro-phied and subcolumns well differentiated, the upper end seems in control ofthe huge big toe (and also partially of the large-sized second and third toes).while the motor center of the little toe is apparently located at the lowerend. The immense bulk of the fore leg of the mole is associated with a cor-responding differentiation of its spinal centers. The development of a peripheralpart is correlated with a commensurate structure on the central side.

    鼹鼠的前足约为後足的3倍。本研究用二个成长鼹鼠的脊髓,作连续染片,比较颈腰膨大部中前後肢的运动中枢的形态。若综合比较颈腰膨大部前角的运动细胞(肢肌的中枢)的数量,颈部约当腰部的2.5—2.8倍。若单独比较前角后部的运动细胞(後外侧柱和後後外侧柱——足肌的中枢)的数量,颈部竟大到腰部的3.4—4.0倍。支配足肌的二柱细胞巨大,分出亚柱,胞团外拓,形成一个新角;有些阶段,它更大过原来的前角。後後外柱的上端比下端发展得多。上端细胞巨大,亚群明显,似主管奇大的踇趾(和二、三趾);小趾的中枢似在下端。鼹鼠前肢的(厂龙)大联系脊髓中枢的分化。周缘部的发展程度与中枢部的形态是相系的。
