[From entry CCXVIII for ι Ori] There is a glow about this object, when viewed under favouring circumstances; yet I cannot assert that the nebulosity in which it is enveloped, is clearly seen. But under proper means it is well worth scrutiny; for nebulous stars are certainly among the most remarkable objects in the heavens, and perhaps should be distinguished from stellar nebulæ in being of a less doubtful character, as to the state of condensation, the central matter in such being suddenly vivid, and sharply defined.
