    The viscosities of five fractionated polymethylmethacrylate samples in benzene have beendetermined in an Ubbelohde dilution viscometer under various external hydrostatic pressures.With the weight average molecular weights obtained from light scattering,the following[η]-Mrelationships are obtained for molecular weights ranging from 0.2 to 4.5×10~6(25℃):under no external pressure [η]=3.80×10~(-3) M~(0.79) ml/gwhen S_R=55 dyne/cm~2 [η]=12.6×10~(-3) M~(0.70)when D_R=5000 sec~(-1) [η]=8.37×10~(-3) M~(0.73)It is pointed out that the shear rate dependence of α has its significance when the theory of intrin-sic viscosity is being applied to the experimental data.The slope constants k' and β of the viscositydata show only slight dependence on S_R or D_R,in disagreement with the results of otherinvestigators.The apparatus used for light scattering measurements is described and the valuesof A_2 and <~2>_z obtained for the polymethylmethacrylate fractions in acetone are given.

    In this work the results of measurement are given for the velocity of ultrasonic waves in suspended monodispersed particles-the spore of lycoperdon in some solvents. The measurement is carried out at different temperatures (from 10 to 60℃) and concentrations (from 12 to 70%) by an ultrasonic interferometer of constant frequency at 1 Mhz. On the basis of the data, the behaviour of variation of ultrasound velocity in suspended matters under different conditions is investigated in detail. It is shown that, for the given suspended matter, the sound velocity square obeys the formula of additivity. The compressibility of the particles under consideration for different temperatures is calculated according to the Herzfeld's simplified formula.

    The present paper reports the using of the tight cell which is made of thin, colorless plastics and in which a piece of hygrometric paper is enclosed to measure the transpiration intensity of leaves. Judging from the authors' data, this method of measurement is superior to the ordinary hygrometric paper method of the qualitative measurement of transpiration intensity in being fairly convenient and accurate. By reforming its fashion, the tight cell may also be adopted for measuring the transpiration intensity of young stems or. branches of woody plants.
