We published in the previous issue of our Bulletin the results of our general investigation of the polarization of the solar Corona observed at the total eclipse on the 21-th of September, 1941. The present note contains the results of additional measurements of the degree and direction of the plane of polarization in the streamers of the solar Corona as well as in the regions free of them. The study of the degree and direction of the plane of polarization of the Corona in both its above mentioned regions represents special interest in connection with the study of the shape and physical nature of the coronal rays. The measuring of the rays of Corona and its other details requires special treatment. I was forced to perform my measurements using the objective photoelectric microphotometer, although it would have been much better to measure the negatives on selfrecording microphotometer that would have given us the possibility of introducing into the formulae (7a) and (7b) of our previous paper the values a, b and c exactly corresponding to the same coronal points. We have used all the negatives present for the photographic rays as well as for the visual ones. On each negative we measured 15 radii, 8 of them along the coronal rays and 7 between the rays. On the first case we measured along the whole length of the ray taking in view its maximum intensity and for the rays inclined to the equator the measurements were made along the preliminary drawn lines. Each plate was measured twice and the arithmetical mean was taken as a result of measurements. The corresponding mean.quadratic error is ±8%. The results of measuring and computations a«e represented in Table I. Finally we tried to examine the law of the intensity decrease with distance from the solar limb although it is true our negatives were not quite suitable for this purposes due to their comparative small scale. Table III is based on the data received from the plate. We found it quite sufficient to the purpose as the two others gave us similar results. Generally it may be concluded that n is greater for the polarized than for the nonpolarized rays of the Corona. January, 1944
