YOUR readers may be interested to learn that the light of the comet is by no means strongly polarised. On the 2nd and 4th instant I examined it with a double-image prism, but could not with certainty detect any difference between the brightness of the two images. I also examined it with a plate of right- and left-handed quartz in the principal focus of the 4-inch telescope and a Nicol's prism packed among the lenses of the eyepiece, but could not detect any traces of colour. With a Savant placed between the eyepiece and the eye no bands were delectable. But on the 6th, about midnight, when the comet was shining very brightly, I could perceive a difference in the brightness of the twj images with the double-image prism, indicating polarisition in the plane passing through the sun's estimated place. But I was still unable to detect any traces of polarisation either with a Savant or Biquariz, or with a plate cut from a natural crystal of right- and left-handed quartz giving a band across the field in which the two crystals overlap ; a form of polariscope whieh has been found on other occasions very delicate for faint lights.
