✦ Synopsis

The polarization of light observed near the Sun's limb steeply goes down from the blue to the red part of the spectrum. New measurements performed through near--infrared filters (the characteristics of which are displayed in Table I) have shown that this behaviour holds up to 8000/~ (Table II). On the other hand, we have found that the proportion of polarized light remains nearly constant between 8000 and 10000 .&; it is about 15 millionths at 25" from the limb, at least if our measurements have not been biased by any unknown polarizing process in the terrestrial atmosphere.
